If you wanted to create a Debian package to fulfill these wishes     and to share your work with the community, you are the target audience of this guide as a prospective Debian maintainer. ^[2] Welcome to the Debian community. Debian has many social and technical rules and conventions to follow since it is a large volunteer organization with history.     Debian also has developed a huge array of packaging tools and archive maintenance tools to build consistent sets of binary packages addressing many technical objectives: * packages build across many architectures (「「Variables for debian/rules」」) * reproducible build (「「Reproducible build」」) * clean build under clearly specified package dependencies and patches (「「debian/control file」」, 「「debian/patches/* files」」, 「「sbuild setup」」) * optimal splits into multiple binary packages (「「Split of a     Debian binary package」」) * smooth library transitions (「「Library transition」」) * interactive installation customization (「「debconf」」) * multiarch support (「「マルチアーチ」」) * security enhancement using specific compiler flags (「「 Compiler hardening」」) * continuous integration (「「Continuous integration」」) * boot strapping (「「Bootstrapping」」) * …​ These make it somewhat overwhelming for many new prospective     Debian maintainers to get involved with Debian. This guide tries to provide entry points for them to get started. It describes the following: * What you should know before getting involved with Debian as a prospective maintainer. * What it looks like to make a simple Debian package.     * What kind of rules exist for making the Debian package. * Tips for making the Debian package. * Examples of making Debian packages for several typical scenarios. The author felt limitations of updating the original 「New Maintainers' Guide」 with the dh-make package and decided to create an alternative tool and its matching document to address modern requirements such as multi-arch. The result was the     debmake package version: 4.0 in 2013. The current debmake is version: 4.5.0. It comes with this updated 「Guide for Debian Maintainers」 in the debmake-doc (version: 1.20-1) package. (In 2016, dh-make was ported from perl to python with updated features.) Many chores and tips have been integrated into the debmake     command allowing this guide to be terse. This guide also offers many packaging examples for you to get started. 注意     It takes many hours to properly create and maintain Debian packages. The Debian maintainer must be both technically competent and diligent to take up this challenge. Some important topics are explained in detail. Some of them may look irrelevant to you. Please be patient. Some corner cases are     skipped. Some topics are only covered by the external pointers. These are intentional choices to keep this guide simple and maintainable. --------------------------------------------------------------------- ^[1] You do need to know a little about Unix programming but you     certainly don’t need to be a wizard. You can learn about the basic handling of a Debian system from the 「Debian Reference」. It contains some pointers to learn about Unix programming, too. ^[2] If you are not interested in sharing the Debian package, you     can certainly work around your local situation by compiling and installing the fixed upstream source package into /usr/local/. 第2章 Overview The Debian packaging of the package-1.0.tar.gz, containing a     simple C source following the 「GNU Coding Standards」 and 「FHS 」, can be done with the debmake command as follows. $ tar -xvzf package-1.0.tar.gz $ cd package-1.0     $ debmake ... Make manual adjustments of generated configuration files $ debuild If manual adjustments of generated configuration files are     skipped, the generated binary package lacks meaningful package description but still functions well under the dpkg command to be used for your local deployment. 注意 The debmake command only provides decent template files. These     template files must be manually adjusted to their perfection to comply with the strict quality requirements of the Debian archive, if the generated package is intended for general consumption.     If you are new to Debian packaging, do not worry about the details and just get the big picture instead. If you have been exposed to Debian packaging, this looks vgry     much like the dh_make command. This is because the debmake command is intended to replace functions offered historically by the dh_make command. ^[3]     The debmake command is designed with the following features: * modern packaging style + debian/copyright: 「DEP-5」 compliant + debian/control: substvar support, multiarch support, multi binary packages, …​ + debian/rules: dh syntax, compiler hardening options, …​ * flexibility + many options (see 「「debmake -b」」, 「14章debmake(1) manpage」, and 「15章debmake options」)     * sane default actions + execute non-stop with clean results + generate the multiarch package, unless the -m option is explicitly specified. + generate the non-native Debian package with the Debian source format 「3.0 (quilt)」, unless the -n option is explicitly specified. * extra utility + verification of the debian/copyright file against the current source (see 「「debmake -k」」) The debmake command delegates most of the heavy lifting to its     back-end packages: debhelper, dpkg-dev, devscripts, sbuild, schroot, etc. ヒント     Make sure to protect the arguments of the -b, -f, -l, and -w options from shell interference by quoting them properly. ヒント     The non-native Debian package is the normal Debian package. ヒント     The detailed log of all the package build examples in this document can be obtained by following the instructions in 「「 Details」」. 注記     The generation of the debian/copyright file, and the outputs from the -c (see 「「debmake -cc」」) and -k (see 「「debmake -k」」) options involve heuristic operations on the copyright and license information. They may produce some erroneous results. --------------------------------------------------------------------- ^[3] The deb-make command was popular before the dh_make command.     The current debmake package starts its version from 4.0 to avoid version overlaps with the obsolete debmake package, which provided the deb-make command. 第3章 Prerequisites     Here are the prerequisites which you need to understand before you to get involved with Debian. 3.1. People around Debian     Debian 界隈では異なる役割で色々なタイプの人が交流しています: * upstream author (アップストリームの作者): 元のプログラムを作 った人です。 * upstream maintainer (アップストリームのメンテナー): 現在プロ グラムをメンテナンスしている人です。 * maintainer (メンテナー): プログラムの Debian パッケージを作成 している人です。 * sponsor (スポンサー): メンテナーのパッケージを、(内容をチェッ     クした後で)公式 Debian パッケージアーカイブにアップロードする のを手伝う人です。 * mentor (指導役): 新米メンテナーをパッケージを作成等で手助けす る人です。 * Debian Developer (Debian デベロッパー) (DD): 公式 Debian パッ ケージアーカイブへの全面的アップロード権限を持っているDebian プロジェクトのメンバーです。 * Debian Maintainer (Debian メンテナー) (DM): 公式 Debian パッ ケージアーカイブへの限定的アップロード権限持っている人です。 Please note that you can’t become an official Debian Developer (DD) overnight, because it takes more than technical skill.     Please do not be discouraged by this. If it is useful to others, you can still upload your package either as a maintainer through a sponsor or as a Debian Maintainer. Please note that you do not need to create any new packages to become an official Debian Developer. Contributing to the existing     packages can provide a path to becoming an official Debian Developer too. There are many packages waiting for good maintainers (see 「"`「Contribution approaches」」`"). 3.2. How to contribute     Please refer to the following to learn how to contribute to Debian: * 「How can you help Debian?」 (official) * 「The Debian GNU/Linux FAQ, Chapter 13 - Contributing to the     Debian Project」 (semi-official) * 「Debian Wiki, HelpDebian」 (supplemental) * 「Debian New Member site」 (official) * 「Debian Mentors FAQ」 (supplemental) 3.3. Debianにおける社会ダイナミクス     Please understand Debian’s social dynamics to prepare yourself for interactions with Debian: * 我々全員はボランティアです。 + You can’t impose on others what to do. + 自分自身で行う意欲を持つべきです。 * 友好的な協力が推進力です。 + Your contribution should not over-strain others. + あなたの寄与は他人に評価されて初めて価値があります。 * Debian は教師の注意が自動的にあなたに注がれるあなたの学校とは     違います。 + 多様な案件の独学能力を持つべきです。 + 他ボランティアに注意を払ってもらうことは貴重なリソースで す。 * Debian は常に改良されています。 + あなたには高品質パッケージを作成することが期待されていま す。 + You should adapt yourself to change. Since we focus only on the technical aspects of the packaging in     the rest of this guide, please refer to the following to understand the social dynamics of Debian:     * 「Debian: 17 years of Free Software, "do-ocracy", and democracy」 (Introductory slides by the ex-DPL) 3.4. Technical reminders Here are some technical reminders to accommodate other     maintainers to work on your package easily and effectively to maximize the output of Debian as a whole. * Make your package easy to debug. + Keep your package simple. + Don’t over-engineer your package.     * Keep your package well-documented. + Use readable code style. + Make comments in code. + Format code consistently. + Maintain the git repository ^[4] of the package. 注記     Debugging of software tends to consume more time than writing the initial working software.     It is unwise to run your base system under the unstable suite even for the development system. * Creation of binary deb packages and their verification should use minimal unstable chroot described in 「「sbuild setup」」     . * Basic interactive package development activities should use unstable chroot described in 「「Persistent chroot setup」」. 注記     Advanced package development activities such as testing of full Desktop systems, network daemons, and system installer packages, should use unstable suite running under the 「virtualization」. 3.5. Debian documentation     Please make yourself ready to read the pertinent part of the latest Debian documentation to generate perfect Debian packages: * 「Debian Policy Manual」 + The official 「must follow」 rules (https:// www.debian.org/doc/devel-manuals#policy) * 「Debian Developer’s Reference」     + The official 「best practice」 document (https:// www.debian.org/doc/devel-manuals#devref) * 「Guide for Debian Maintainers」 — this guide + A 「tutorial reference」 document (https://www.debian.org /doc/devel-manuals#debmake-doc) All these documents are published to https://www.debian.org using the unstable suite versions of corresponding Debian packages. If     you wish to have local accesses to all these documents from your base system, please consider to use techniques such as 「 apt-pinning」 and 「chroot」. If this guide contradicts the official Debian documentation, the     official Debian documentation is correct. Please file a bug report on the debmake-doc package using the reportbug command.     Here are alternative tutorial documents, which you may read along with this guide: * 「Debian Packaging Tutorial」 + https://www.debian.org/doc/devel-manuals# packaging-tutorial + https://packages.qa.debian.org/p/packaging-tutorial.html * 「Ubuntu Packaging Guide」 (Ubuntu is Debian based.)     + http://packaging.ubuntu.com/html/ * 「Debian New Maintainers' Guide」 (predecessor of this tutorial, deprecated) + https://www.debian.org/doc/devel-manuals#maint-guide + https://packages.qa.debian.org/m/maint-guide.html ヒント     When reading these, you may consider using the debmake command in place of the dh_make command. 3.6. Help resources Before you decide to ask your question in some public place,     please do your part of the effort, i.e., read the fine documentation: * package information available through the aptitude, apt-cache , and dpkg commands. * files in /usr/share/doc/package for all pertinent packages. * contents of man command for all pertinent commands.     * contents of info command for all pertinent commands. * contents of 「debian-mentors@lists.debian.org mailing list archive」. * contents of 「debian-devel@lists.debian.org mailing list archive」. Your desired information can be found effectively by using a     well-formed search string such as 「keyword site:lists.debian.org 」 to limit the search domain of the web search engine. Making a small test package is a good way to learn details of the     packaging. Inspecting existing well maintained packages is the best way to learn how other people make packages.     If you still have questions about the packaging, you can ask them interactively: * debian-mentors@lists.debian.org mailing list. (This mailing list is for the novice.) * debian-devel@lists.debian.org mailing list. (This mailing list is for the expert.) * IRC such as #debian-mentors. * Teams focusing on a specific set of packages. (Full list at     https://wiki.debian.org/Teams) * Language-specific mailing lists. + 「debian-devel-{french,italian,portuguese,spanish} @lists.debian.org」 + 「debian-chinese-gb@lists.debian.org」 (This mailing list is for general (Simplified) Chinese discussion.) + 「debian-devel@debian.or.jp」     あなたがするべき努力をした後に適切に質問すれば、より経験を持った Debian デベロッパーは喜んで助けてくれるでしょう。 注意     Debian development is a moving target. Some information found on the web may be outdated, incorrect, and non-applicable. Please use them carefully. 3.7. Archive situation     Please realize the situation of the Debian archive. * Debian already has packages for most kinds of programs. * The number of packages already in the Debian archive is     several tens of times greater than that of active maintainers. * Unfortunately, some packages lack an appropriate level of attention by the maintainer. Thus, contributions to packages already in the archive are far     more appreciated (and more likely to receive sponsorship for uploading) by other maintainers. ヒント     The wnpp-alert command from the devscripts package can check for installed packages up for adoption or orphaned. ヒント     The how-can-i-help package can show opportunities for contributing to Debian on packages installed locally. 3.8. Contribution approaches     Here is pseudo-Python code for your contribution approaches to Debian with a program: if exist_in_debian(program): if is_team_maintained(program): join_team(program) if is_orphaned(program): # maintainer: Debian QA Group adopt_it(program) elif is_RFA(program): # Request for Adoption adopt_it(program) else: if need_help(program): contact_maintainer(program) triaging_bugs(program) preparing_QA_or_NMU_uploads(program) else: leave_it(program) else: # new packages if not is_good_program(program): give_up_packaging(program)     elif not is_distributable(program): give_up_packaging(program) else: # worth packaging if is_ITPed_by_others(program): if need_help(program): contact_ITPer_for_collaboration(program) else: leave_it_to_ITPer(program) else: # really new if is_applicable_team(program): join_team(program) if is_DFSG(program) and is_DFSG(dependency(program)): file_ITP(program, area="main") # This is Debian elif is_DFSG(program): file_ITP(program, area="contrib") # This is not Debian else: # non-DFSG file_ITP(program, area="non-free") # This is not Debian package_it_and_close_ITP(program)     Here: * For exist_in_debian(), and is_team_maintained(); check: + the aptitude command + 「Debian packages」 web page + Debian wiki 「Teams」 page * For is_orphaned(), is_RFA(), and is_ITPed_by_others(); check: + The output of the wnpp-alert command. + 「Work-Needing and Prospective Packages」 + 「Debian Bug report logs: Bugs in pseudo-package wnpp in unstable」 + 「Debian Packages that Need Lovin'」 + 「Browse wnpp bugs based on debtags」 * For is_good_program(), check:     + The program should be useful. + The program should not introduce security and maintenance concerns to the Debian system. + The program should be well documented and its code needs to be understandable (i.e. not obfuscated). + The program’s authors agree with the packaging and are amicable to Debian. ^[5] * For is_it_DFSG(), and is_its_dependency_DFSG(); check: + 「Debian Free Software Guidelines」 (DFSG). * For is_it_distributable(), check: + The software must have a license and it should allow its distribution.     You either need to file an ITP or adopt a package to start working on it. See the 「Debian Developer’s Reference」: * 「5.1. New packages」.     * 「5.9. Moving, removing, renaming, orphaning, adopting, and reintroducing packages」. 3.9. Novice contributor and maintainer The novice contributor and maintainer may wonder what to learn to     start your contribution to Debian. Here are my suggestions depending on your focus: * Packaging + Basics of the POSIX shell and make. + Some rudimentary knowledge of Perl and Python.     * Translation + Basics of how the PO based translation system works. * Documentation + Basics of text markups (XML, ReST, Wiki, …​). The novice contributor and maintainer may wonder where to start     your contribution to Debian. Here are my suggestions depending on your skills: * POSIX shell, Perl, and Python skills: + Send patches to the Debian Installer. + Send patches to the Debian packaging helper scripts such as devscripts, sbuild, schroot, etc. mentioned in this document. * C and C++ skills: + Send patches to the packages with the required and     important priorities. * Non-English skills: + Send patches to the PO file of the Debian Installer. + Send patches to the PO file of the packages with the required and important priorities. * Documentation skills: + Update contents on 「Debian Wiki」. + Send patches to the existing 「Debian Documentation」.     These activities should give you good exposure to the other Debian people to establish your credibility.     The novice maintainer should avoid packaging programs with the high security exposure: * setuid or setgid program     * daemon program * program installed in the /sbin/ or /usr/sbin/ directories     When you gain more experience in packaging, you’ll be able to package such programs. ---------------------------------------------------------------------     ^[4] The overwhelming number of Debian maintainers use git over other VCS systems such as hg, bzr, etc. ^[5] This is not the absolute requirement. The hostile upstream     may become a major resource drain for us all. The friendly upstream can be consulted to solve any problems with the program. 第4章 Tool Setups     The build-essential package must be installed in the build environment.     The devscripts package should be installed in the development environment of the maintainer. It is a good idea to install and set up all of the popular set of     packages mentioned in this chapter. These enable us to share the common baseline working environment, although these are not necessarily absolute requirements. Please also consider to install the tools mentioned in the 「     Overview of Debian Maintainer Tools」 in the 「Debian Developer’s Reference」, as needed. 注意     Tool setups presented here are only meant as an example and may not be up-to-date with the latest packages on the system. Debian development is a moving target. Please make sure to read the pertinent documentation and update the configuration as needed. 4.1. Email setup Various Debian maintenance tools recognize your email address and     name to use by the shell environment variables $DEBEMAIL and $DEBFULLNAME.     Let’s set these environment variables by adding the following lines to ~/.bashrc ^[6]. Add to the ~/.bashrc file.      DEBEMAIL="osamu@debian.org" DEBFULLNAME="Osamu Aoki" export DEBEMAIL DEBFULLNAME 注記     The above is for the author of this manual. The configuration and operation examples presented in this manual use these email address and name settings. You must use your email address and name for your system. 4.2. mc setup The mc command offers very easy ways to manage files. It can open     the binary deb file to check its content by pressing the Enter key over the binary deb file. It uses the dpkg-deb command as its back-end. Let’s set it up to support easy chdir as follows. Add to the ~/.bashrc file.      # mc related if [ -f /usr/lib/mc/mc.sh ]; then . /usr/lib/mc/mc.sh fi 4.3. git setup     Nowadays, the git command is the essential tool to manage the source tree with history.     The global user configuration for the git command such as your name and email address can be set in ~/.gitconfig as follows.     $ git config --global user.name "Osamu Aoki" $ git config --global user.email osamu@debian.org     If you are too accustomed to the CVS or Subversion commands, you may wish to set several command aliases as follows.     $ git config --global alias.ci "commit -a" $ git config --global alias.co checkout     You can check your global configuration as follows.     $ git config --global --list ヒント     It is essential to use some GUI git tools like gitk or gitg to work effectively with the history of the git repository. 4.4. quilt setup The quilt command offers a basic method for recording     modifications. For the Debian packaging, it should be customized to record modifications in the debian/patches/ directory instead of its default patches/ directory. In order to avoid changing the behavior of the quilt command itself, let’s create an alias dquilt for the Debian packaging by     adding the following lines to the ~/.bashrc file. The second line provides the same shell completion feature of the quilt command to the dquilt command. Add to the ~/.bashrc file.      alias dquilt="quilt --quiltrc=${HOME}/.quiltrc-dpkg" . /usr/share/bash-completion/completions/quilt complete -F _quilt_completion $_quilt_complete_opt dquilt     Then let’s create ~/.quiltrc-dpkg as follows. d=. while [ ! -d $d/debian -a `readlink -e $d` != / ]; do d=$d/..; done if [ -d $d/debian ] && [ -z $QUILT_PATCHES ]; then # if in Debian packaging tree with unset $QUILT_PATCHES QUILT_PATCHES="debian/patches"     QUILT_PATCH_OPTS="--reject-format=unified" QUILT_DIFF_ARGS="-p ab --no-timestamps --no-index --color=auto" QUILT_REFRESH_ARGS="-p ab --no-timestamps --no-index" QUILT_COLORS="diff_hdr=1;32:diff_add=1;34:diff_rem=1;31:diff_hunk=1;33:" QUILT_COLORS="${QUILT_COLORS}diff_ctx=35:diff_cctx=33" if ! [ -d $d/debian/patches ]; then mkdir $d/debian/patches; fi fi See quilt(1) and 「How To Survive With Many Patches or     Introduction to Quilt (quilt.html)」 on how to use the quilt command.     See 「「Step 3 (alternatives): Modification to the upstream source」」 for example usages. 4.5. devscripts setup     The debsign command, included in the devscripts package, is used to sign the Debian package with your private GPG key. The debuild command, included in the devscripts package, builds     the binary package and checks it with the lintian command. It is useful to have verbose outputs from the lintian command.     You can set these up in ~/.devscripts as follows. DEBUILD_DPKG_BUILDPACKAGE_OPTS="-i -I -us -uc"     DEBUILD_LINTIAN_OPTS="-i -I --show-overrides" DEBSIGN_KEYID="Your_GPG_keyID" The -i and -I options in DEBUILD_DPKG_BUILDPACKAGE_OPTS for the     dpkg-source command help rebuilding of Debian packages without extraneous contents (see 「7章Sanitization of the source」).     Currently, an RSA key with 4096 bits is a good idea. See 「 Creating a new GPG key」. 4.6. sbuild setup The sbuild package provides a clean room (「chroot」) build     environment. It offers this efficiently with the help of schroot using the bind-mount feature of the modern Linux kernel. Since it is the same build environment as the Debian’s buildd     infrastructure, it is always up to date and comes full of useful features.     It can be customized to offer following features: * The schroot package to boost the chroot creation speed. * The lintian package to find bugs in the package. * The piuparts package to find bugs in the package.     * The autopkgtest package to find bugs in the package. * The ccache package to boost the gcc speed. (optional) * The libeatmydata1 package to boost the dpkg speed. (optional) * The parallel make to boost the build speed. (optional)     Let’s set up sbuild environment ^[7]: $ sudo apt install sbuild piuparts autopkgtest lintian     $ sudo apt install sbuild-debian-developer-setup $ sudo sbuild-debian-developer-setup -s unstable     Let’s update your group membership to include sbuild and verify it: $ newgrp -     $ id uid=1000() gid=1000() groups=...,132(sbuild)     Here, 「reboot of system」 or 「kill -TERM -1」 can be used instead to update your group membership ^[8] .     Let’s create the configuration file ~/.sbuildrc in line with recent Debian practice of 「source-only-upload」 as: cat >~/.sbuildrc << 'EOF' ############################################################################## # PACKAGE BUILD RELATED (source-only-upload as default) ############################################################################## # -d $distribution = 'unstable'; # -A $build_arch_all = 1; # -s $build_source = 1; # --source-only-changes $source_only_changes = 1; # -v $verbose = 1;     ############################################################################## # POST-BUILD RELATED (turn off functionality by setting variables to 0) ############################################################################## $run_lintian = 1; $lintian_opts = ['-i', '-I']; $run_piuparts = 1; $piuparts_opts = ['--schroot', 'unstable-amd64-sbuild']; $run_autopkgtest = 1; $autopkgtest_root_args = ''; $autopkgtest_opts = [ '--', 'schroot', '%r-%a-sbuild' ]; ############################################################################## # PERL MAGIC ############################################################################## 1; EOF 注記 There are some exceptional cases such as NEW uploads, uploads     with NEW binary packages, and security uploads where you can’t do source-only-upload but are required to upload with binary packages. The above configuration needs to be adjusted for those exceptional cases.     Following document assumes that sbuild is configured this way.     Edit this to your needs. Post-build tests can be turned on and off by assigning 1 or 0 to the corresponding variables, 警告     The optional customization may cause negative effects. In case of doubts, disable them. 注記     The parallel make may fail for some existing packages and may make the build log difficult to read. ヒント     Many sbuild related hints are available at 「「Note on sbuild」」 and 「https://wiki.debian.org/sbuild」 . 4.7. Persistent chroot setup 注記     Use of independent copied chroot filesystem prevents contaminating the source chroot used by sbuild. For building new experimental packages or for debugging buggy     packages, let’s setup dedicated persistent chroot 「 source:unstable-amd64-desktop」 by: $ sudo cp -a /srv/chroot/unstable-amd64-sbuild-$suffix /srv/chroot/unstable-amd64-desktop $ sudo tee /etc/schroot/chroot.d/unstable-amd64-desktop << EOF [unstable-desktop] description=Debian sid/amd64 persistent chroot groups=root,sbuild     root-groups=root,sbuild profile=desktop type=directory directory=/srv/chroot/unstable-amd64-desktop union-type=overlay EOF Here, desktop profile is used instead of sbuild profile. Please     make sure to adjust /etc/schroot/desktop/fstab to make package source accessible from inside of the chroot.     You can log into this chroot 「source:unstable-amd64-desktop」 by:     $ sudo schroot -c source:unstable-amd64-desktop 4.8. gbp setup     The git-buildpackage package offers the gbp(1) command. Its user configuration file is ~/.gbp.conf. # Configuration file for "gbp " [DEFAULT] # the default build command:     builder = sbuild # use pristine-tar: pristine-tar = True # Use color when on a terminal, alternatives: on/true, off/false or auto color = auto 4.9. HTTP proxy You should set up a local HTTP caching proxy to save the     bandwidth for the Debian package repository access. There are several choices: * Specialized HTTP caching proxy using the apt-cacher-ng     package. * Generic HTTP caching proxy (squid package) configured by squid-deb-proxy package In order to use this HTTP proxy without manual configuration     adjustment, it’s a good idea to install either auto-apt-proxy or squid-deb-proxy-client package to everywhere. 4.10. Private Debian repository     You can set up a private Debian package repository with the reprepro package. 4.11. Virtual machines     For testing GUI application, it is a good idea to have virtual machines. Install virt-manager and qemu-kvm packages.     Use of chroot and virtual machines allows us not to update the whole host PC to the latest unstable suite. 4.12. Local network with virtual machines In order to access virtual machines easily over the local     network, setting up multicast DNS service discovery infrastructure by installing avahi-utils is a good idea.     For all running virtual machines and the host PC, we can use each host name appended with .local for SSH to access each other. --------------------------------------------------------------------- ^[6] This assumes you are using Bash as your login shell. If you     use some other login shell such as Z shell, use their corresponding configuration files instead of ~/.bashrc.     ^[7] Be careful since some older HOWTOs may use different chroot setups.     ^[8] Simply 「logout and login under some modern GUI Desktop environment」 may not update your group membership. 第5章 Simple packaging There is an old Latin saying: 「Longum iter est per praecepta,     breve et efficax per exempla」 (「It’s a long way by the rules, but short and efficient with examples」). 5.1. Packaging tarball     Here is an example of creating a simple Debian package from a simple C source using the Makefile as its build system.     Let’s assume this upstream tarball to be debhello-0.0.tar.gz.     This type of source is meant to be installed as a non-system file as: Basics for the install from the upstream tarball.      $ tar -xzmf debhello-0.0.tar.gz $ cd debhello-0.0 $ make $ make install Debian packaging requires changing this 「make install」 process     to install files to the target system image location instead of the normal location under /usr/local. 注記     Examples of creating a Debian package from other complicated build systems are described in 「13章More Examples」. 5.2. Big picture The big picture for building a single non-native Debian package     from the upstream tarball debhello-0.0.tar.gz can be summarized as: * The maintainer obtains the upstream tarball debhello-0.0.tar.gz and untars its contents to the debhello-0.0 directory. * The debmake command debianizes the upstream source tree by adding template files only in the debian directory.     + The debhello_0.0.orig.tar.gz symlink is created pointing to the debhello-0.0.tar.gz file. + The maintainer customizes template files. * The debuild command builds the binary package from the debianized source tree. + debhello-0.0-1.debian.tar.xz is created containing the debian directory. Big picture of package building.  $ tar -xzmf debhello-0.0.tar.gz     $ cd debhello-0.0 $ debmake ... manual customization $ debuild ... ヒント     The debuild command in this and following examples may be substituted by equivalent commands such as the sbuild command. ヒント     If the upstream tarball in the .tar.xz format is available, use it instead of the one in the .tar.gz and .tar.bz2 formats. The xz compression format offers the better compression than the gzip and bzip2 compressions. 5.3. What is debmake? 注記     Actual packaging activities are often performed manually without using debmake while referencing only existing similar packages and 「Debian Policy Manual」.     The debmake command is the helper script for the Debian packaging. (「14章debmake(1) manpage」) * It creates good template files for the Debian packages. * It always sets most of the obvious option states and values to reasonable defaults. * It generates the upstream tarball and its required symlink if     they are missing. * It doesn’t overwrite the existing configuration files in the debian/ directory. * It supports the multiarch package. * It provides short extracted license texts as debian/copyright in decent accuracy to help license review.     These features make Debian packaging with debmake simple and modern. In retrospective, I created debmake to simplify this     documentation. I consider debmake to be more-or-less a demonstration session generator for tutorial purpose. The debmake command isn’t the only helper script to make a Debian     package. If you are interested alternative packaging helper tools, please see: * Debian wiki: 「AutomaticPackagingTools」 — Extensive     comparison of packaging helper scripts * Debian wiki: 「CopyrightReviewTools」 — Extensive comparison of copyright review helper scripts 5.4. What is debuild?     Here is a summary of commands similar to the debuild command. * The debian/rules file defines how the Debian binary package is built. * The dpkg-buildpackage command is the official command to build the Debian binary package. For normal binary build, it executes roughly: + 「dpkg-source --before-build」 (apply Debian patches, unless they are already applied) + 「fakeroot debian/rules clean」 + 「dpkg-source --build」 (build the Debian source package) + 「fakeroot debian/rules build」 + 「fakeroot debian/rules binary」 + 「dpkg-genbuildinfo」 (generate a *.buildinfo file)     + 「dpkg-genchanges」 (generate a *.changes file) + 「fakeroot debian/rules clean」 + 「dpkg-source --after-build」 (unapply Debian patches, if they are applied during --before-build) + 「debsign」 (sign the *.dsc and *.changes files) o If you followed 「「devscripts setup」」 to set the -us and -uc options, this step is skipped and you must run the debsign command manually. * The debuild command is a wrapper script of the dpkg-buildpackage command to build the Debian binary package under the proper environment variables. * The sbuild command is a wrapper script to build the Debian binary package under the proper chroot environment with the proper environment variables. 注記     See dpkg-buildpackage(1) for exact details. 5.5. Step 1: Get the upstream source     Let’s get the upstream source. Download debhello-0.0.tar.gz.  $ wget http://www.example.org/download/debhello-0.0.tar.gz ... $ tar -xzmf debhello-0.0.tar.gz $ tree .     ├── debhello-0.0 │   ├── Makefile │   ├── README.md │   └── src │   └── hello.c └── debhello-0.0.tar.gz 3 directories, 4 files     Here, the C source hello.c is a very simple one. hello.c.  $ cat debhello-0.0/src/hello.c #include     int main() { printf("Hello, world!\n"); return 0; }     Here, the Makefile supports 「GNU Coding Standards」 and 「FHS」. Notably: * build binaries honoring $(CPPFLAGS), $(CFLAGS), $(LDFLAGS), etc.     * install files with $(DESTDIR) defined to the target system image * install files with $(prefix) defined, which can be overridden to be /usr Makefile.  $ cat debhello-0.0/Makefile prefix = /usr/local all: src/hello src/hello: src/hello.c @echo "CFLAGS=$(CFLAGS)" | \ fold -s -w 70 | \ sed -e 's/^/# /' $(CC) $(CPPFLAGS) $(CFLAGS) $(LDCFLAGS) -o $@ $^     install: src/hello install -D src/hello \ $(DESTDIR)$(prefix)/bin/hello clean: -rm -f src/hello distclean: clean uninstall: -rm -f $(DESTDIR)$(prefix)/bin/hello .PHONY: all install clean distclean uninstall 注記     The echo of the $(CFLAGS) variable is used to verify the proper setting of the build flag in the following example. 5.6. Step 2: Generate template files with debmake     The output from the debmake command is very verbose and explains what it does as follows. The output from the debmake command.  $ cd /path/to/debhello-0.0 $ debmake -x1 I: set parameters I: sanity check of parameters I: pkg="debhello", ver="0.0", rev="1" I: *** start packaging in "debhello-0.0". *** I: provide debhello_0.0.orig.tar.gz for non-native Debian package I: pwd = "/path/to" I: $ ln -sf debhello-0.0.tar.gz debhello_0.0.orig.tar.gz I: pwd = "/path/to/debhello-0.0" I: parse binary package settings: I: binary package=debhello Type=bin / Arch=any M-A=foreign I: analyze the source tree I: build_type = make I: scan source for copyright+license text and file extensions I: 50 %, ext = md I: 50 %, ext = c I: check_all_licenses I: ...

Now, debian/* may have a blank line at the top.... The debmake command generates all these template files based on     command line options. Since no options are specified, the debmake command chooses reasonable default values for you: * The source package name: debhello * The upstream version: 0.0 * The binary package name: debhello     * The Debian revision: 1 * The package type: bin (the ELF binary executable package) * The -x option: -x1 (without maintainer script supports for simplicity) 注記     Here, the debmake command is invoked with the -x1 option to keep this tutorial simple. Use of default -x3 option is highly recommended.     Let’s inspect generated template files. The source tree after the basic debmake execution.  $ cd /path/to $ tree . ├── debhello-0.0 │   ├── Makefile │   ├── README.md │   ├── debian │   │   ├── README.Debian │   │   ├── README.source │   │   ├── changelog │   │   ├── clean │   │   ├── control │   │   ├── copyright │   │   ├── dirs │   │   ├── gbp.conf │   │   ├── install     │   │   ├── links │   │   ├── patches │   │   │   └── series │   │   ├── rules │   │   ├── salsa-ci.yml │   │   ├── source │   │   │   ├── format │   │   │   ├── local-options.ex │   │   │   └── local-patch-header.ex │   │   ├── tests │   │   │   └── control │   │   ├── upstream │   │   │   └── metadata │   │   └── watch │   └── src │   └── hello.c ├── debhello-0.0.tar.gz └── debhello_0.0.orig.tar.gz -> debhello-0.0.tar.gz 8 directories, 24 files The debian/rules file is the build script provided by the package     maintainer. Here is its template file generated by the debmake command. debian/rules (template file):  $ cd /path/to/debhello-0.0 $ cat debian/rules #!/usr/bin/make -f # You must remove unused comment lines for the released package. #export DH_VERBOSE = 1 #export DEB_BUILD_MAINT_OPTIONS = hardening=+all #export DEB_CFLAGS_MAINT_APPEND = -Wall -pedantic     #export DEB_LDFLAGS_MAINT_APPEND = -Wl,-O1 %: dh $@ #override_dh_auto_install: # dh_auto_install -- prefix=/usr #override_dh_install: # dh_install --list-missing -X.pyc -X.pyo This is essentially the standard debian/rules file with the dh     command. (There are some commented out contents for you to customize it.) The debian/control file provides the main meta data for the     Debian package. Here is its template file generated by the debmake command. debian/control (template file):  $ cat debian/control Source: debhello Section: unknown Priority: optional Maintainer: "Osamu Aoki" Build-Depends: debhelper-compat (= 13) Standards-Version: 4.6.2 Homepage:     Rules-Requires-Root: no #Vcs-Git: https://salsa.debian.org/debian/debhello.git #Vcs-Browser: https://salsa.debian.org/debian/debhello Package: debhello Architecture: any Multi-Arch: foreign Depends: ${misc:Depends}, ${shlibs:Depends} Description: auto-generated package by debmake This Debian binary package was auto-generated by the debmake(1) command provided by the debmake package. 警告     If you leave 「Section: unknown」 in the template debian/control file unchanged, the lintian error may cause the build to fail. Since this is the ELF binary executable package, the debmake command sets 「Architecture: any」 and 「Multi-Arch: foreign」.     Also, it sets required substvar parameters as 「Depends: $ {shlibs:Depends}, ${misc:Depends}」. These are explained in 「6章 Basics for packaging」. 注記     Please note this debian/control file uses the RFC-822 style as documented in 「5.2 Source package control files — debian/control 」 of the 「Debian Policy Manual」. The use of the empty line and the leading space are significant. The debian/copyright file provides the copyright summary data of     the Debian package. Here is its template file generated by the debmake command. debian/copyright (template file):  $ cat debian/copyright Format: https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/ Upstream-Name: debhello Upstream-Contact: Source: # # Please double check copyright with the licensecheck(1) command.     Files: Makefile README.md src/hello.c Copyright: __NO_COPYRIGHT_NOR_LICENSE__ License: __NO_COPYRIGHT_NOR_LICENSE__ #----------------------------------------------------------------------------... # Files marked as NO_LICENSE_TEXT_FOUND may be covered by the following # license/copyright files. 5.7. Step 3: Modification to the template files     Some manual modification is required to make the proper Debian package as a maintainer. In order to install files as a part of the system files, the $ (prefix) value of /usr/local in the Makefile should be overridden     to be /usr. This can be accommodated by the following the debian/ rules file with the override_dh_auto_install target setting 「 prefix=/usr」. debian/rules (maintainer version):  $ cd /path/to/debhello-0.0 $ vim debian/rules ... hack, hack, hack, ... $ cat debian/rules #!/usr/bin/make -f export DH_VERBOSE = 1     export DEB_BUILD_MAINT_OPTIONS = hardening=+all export DEB_CFLAGS_MAINT_APPEND = -Wall -pedantic export DEB_LDFLAGS_MAINT_APPEND = -Wl,--as-needed %: dh $@ override_dh_auto_install: dh_auto_install -- prefix=/usr Exporting the DH_VERBOSE environment variable in the debian/rules     file as above forces the debhelper tool to make a fine grained build report. Exporting DEB_BUILD_MAINT_OPTION as above sets the hardening     options as described in the 「FEATURE AREAS/ENVIRONMENT」 in dpkg-buildflags(1). ^[9]     Exporting DEB_CFLAGS_MAINT_APPEND as above forces the C compiler to emit all the warnings.     Exporting DEB_LDFLAGS_MAINT_APPEND as above forces the linker to link only when the library is actually needed. ^[10] The dh_auto_install command for the Makefile based build system essentially runs 「$(MAKE) install DESTDIR=debian/debhello」. The     creation of this override_dh_auto_install target changes its behavior to 「$(MAKE) install DESTDIR=debian/debhello prefix=/usr 」.     Here are the maintainer versions of the debian/control and debian /copyright files. debian/control (maintainer version):  $ vim debian/control ... hack, hack, hack, ... $ cat debian/control Source: debhello Section: devel Priority: optional Maintainer: Osamu Aoki Build-Depends: debhelper-compat (= 13)     Standards-Version: 4.6.2 Homepage: https://salsa.debian.org/debian/debmake-doc Rules-Requires-Root: no Package: debhello Architecture: any Multi-Arch: foreign Depends: ${misc:Depends}, ${shlibs:Depends} Description: Simple packaging example for debmake This Debian binary package is an example package.

Step 4: Building package with debuild You can create a non-native Debian package using the debuild     command or its equivalents (see 「「What is debuild?」」) in this source tree. The command output is very verbose and explains what it does as follows. Building package with debuild.  $ cd /path/to/debhello-0.0 $ debuild dpkg-buildpackage -us -uc -ui -i dpkg-buildpackage: info: source package debhello dpkg-buildpackage: info: source version 0.0-1 dpkg-buildpackage: info: source distribution unstable dpkg-buildpackage: info: source changed by Osamu Aoki dpkg-source -i --before-build . dpkg-buildpackage: info: host architecture amd64 debian/rules clean dh clean     dh_auto_clean make -j12 distclean ... debian/rules binary dh binary dh_update_autotools_config dh_autoreconf dh_auto_configure dh_auto_build make -j12 "INSTALL=install --strip-program=true" make[1]: Entering directory '/path/to/debhello-0.0' # CFLAGS=-g -O2 ... Finished running lintian.     You can verify that CFLAGS is updated properly with -Wall and -pedantic by the DEB_CFLAGS_MAINT_APPEND variable. The manpage should be added to the package as reported by the     lintian package, as shown in later examples (see 「13章More Examples」). Let’s move on for now.     Let’s inspect the result. The generated files of debhello version 0.0 by the debuild command:  $ cd /path/to $ tree -FL 1 ./ ├── debhello-0.0/ ├── debhello-0.0.tar.gz     ├── debhello-dbgsym_0.0-1_amd64.deb ├── debhello_0.0-1.debian.tar.xz ├── debhello_0.0-1.dsc ├── debhello_0.0-1_amd64.build ├── debhello_0.0-1_amd64.buildinfo ├── debhello_0.0-1_amd64.changes ├── debhello_0.0-1_amd64.deb └── debhello_0.0.orig.tar.gz -> debhello-0.0.tar.gz 2 directories, 9 files     You see all the generated files. * The debhello_0.0.orig.tar.gz is a symlink to the upstream tarball. * The debhello_0.0-1.debian.tar.xz contains the maintainer generated contents. * The debhello_0.0-1.dsc is the meta data file for the Debian source package.     * The debhello_0.0-1_amd64.deb is the Debian binary package. * The debhello-dbgsym_0.0-1_amd64.deb is the Debian debug symbol binary package.

This sloppy package functions well under the dpkg command, and may be good enough for your local deployment. 5.9. Step 3 (alternatives): Modification to the upstream source The above example did not touch the upstream source to make the     proper Debian package. An alternative approach as the maintainer is to modify files in the upstream source. For example, Makefile may be modified to set the $(prefix) value to /usr. 注記     The above 「「Step 3: Modification to the template files」」 using the debian/rules file is the better approach for packaging for this example. But let’s continue on with this alternative approaches as a leaning experience. In the following, let’s consider 3 simple variants of this alternative approach to generate debian/patches/* files     representing modifications to the upstream source in the Debian source format 「3.0 (quilt)」. These substitute 「「Step 3: Modification to the template files」」 in the above step-by-step example: * 「「Patch by 「diff -u」 approach」」     * 「「Patch by dquilt approach」」 * 「「Patch by 「dpkg-source --auto-commit」 approach」」     Please note the debian/rules file used for these examples doesn’t have the override_dh_auto_install target as follows: debian/rules (alternative maintainer version):  $ cd /path/to/debhello-0.0 $ vim debian/rules ... hack, hack, hack, ... $ cat debian/rules     #!/usr/bin/make -f export DH_VERBOSE = 1 export DEB_BUILD_MAINT_OPTIONS = hardening=+all export DEB_CFLAGS_MAINT_APPEND = -Wall -pedantic export DEB_LDFLAGS_MAINT_APPEND = -Wl,--as-needed %: dh $@ 5.10. Patch by 「diff -u」 approach     Here, the patch file 000-prefix-usr.patch is created using the diff command.

Please read the manpages of the dpkg-source(1), dpkg-buildpackage(1), dpkg (1), dpkg-deb(1), deb(5), etc.     The Debian source package is a set of input files used to build the Debian binary package and is not a single file.     The Debian binary package is a special archive file which holds a set of installable binary data with its associated information.     A single Debian source package may generate multiple Debian binary packages defined in the debian/control file.     The non-native Debian package in the Debian source format 「3.0 (quilt)」 is the most normal Debian source package format. 注記     There are many wrapper scripts. Use them to streamline your workflow but make sure to understand the basics of their internals. 6.1. Packaging workflow The Debian packaging workflow to create a Debian binary package involves generating several specifically named files (see 「「パ     ッケージ名とバージョン」」) as defined in the 「Debian Policy Manual」. This workflow can be summarized in 10 steps with some over simplification as follows. 1. The upstream tarball is downloaded as the package-version .tar.gz file. 2. The upstream tarball is untarred to create many files under the package-version/ directory. 3. The upstream tarball is copied (or symlinked) to the particular filename packagename_version.orig.tar.gz. + the character separating package and version is changed from - (hyphen) to _ (underscore) + .orig is added in the file extension. 4. The Debian package specification files are added to the upstream source under the package-version/debian/ directory. + Required specification files under the debian/ directory: debian/rules The executable script for building the Debian package (see 「「debian/rules file」」) debian/control The package configuration file containing the source package name, the source build dependencies, the binary package name, the binary dependencies, etc. (see 「「debian/control file」」) debian/changelog The Debian package history file defining the upstream package version and the Debian revision in its first line (see 「「debian/changelog file」」) debian/copyright The copyright and license summary (see 「「debian/ copyright file」」) + Optional specification files under the debian/* (see 「「 Other debian/* files」」): + The debmake command invoked in the package-version/ directory may be used to provide the initial template of these configuration files. o Required specification files are generated even with the -x0 option. o The debmake command does not overwrite any existing configuration files. + These files must be manually edited to their perfection according to the 「Debian Policy Manual」 and 「Debian Developer’s Reference」. 5. The dpkg-buildpackage command (usually from its wrapper debuild or sbuild) is invoked in the package-version/ directory to make the Debian source and binary packages by invoking the debian/rules script. + The current directory is set as: 「CURDIR=/path/to/     package-version/」 + Create the Debian source package in the Debian source format 「3.0 (quilt)」 using dpkg-source(1) o package_version.orig.tar.gz (copy or symlink of package-version.tar.gz) o package_version-revision.debian.tar.xz (tarball of debian/ found in package-version/) o package_version-revision.dsc + Build the source using 「debian/rules build」 into $ (DESTDIR) o 「DESTDIR=debian/binarypackage/」 for single binary package ^[11] o 「DESTDIR=debian/tmp/」 for multi binary package + Create the Debian binary package using dpkg-deb(1), dpkg-genbuildinfo(1), and dpkg-genchanges(1). o binarypackage_version-revision_arch.deb o …​ (There may be multiple Debian binary package files.) o package_version-revision_arch.changes o package_version-revision_arch.buildinfo 6. Check the quality of the Debian package with the lintian command. (recommended) + Follow the rejection guidelines from ftp-master. o 「REJECT-FAQ」 o 「NEW checklist」 o 「Lintian Autorejects」 (「lintian tag list」) 7. Test the goodness of the generated Debian binary package manually by installing it and running its programs. 8. After confirming the goodness, prepare files for the normal source-only upload to the Debian archive. 9. Sign the Debian package file with the debsign command using your private GPG key. + Use 「debsign package_version-revision_source.changes」 (normal source-only upload situation) + Use 「debsign package_version-revision_arch.changes」 (exceptional binary upload situation such as NEW uploads, and security uploads) files for the binary Debian package upload. 10. Upload the set of the Debian package files with the dput command to the Debian archive. + Use 「dput package_version-revision_source.changes」 (source-only upload) + Use 「dput package_version-revision_arch.changes」 (binary upload) Test building and confirming of the binary package goodness as     above is the moral obligation as a diligent Debian developer but there is no physical barrier for people to skip such operations at this moment for the source-only upload.     Here, please replace each part of the filename as: * the package part with the Debian source package name * the binarypackage part with the Debian binary package name     * the version part with the upstream version * the revision part with the Debian revision * the arch part with the package architecture (e.g., amd64)     See also 「Source-only uploads」. ヒント     Many patch management and VCS usage strategies for the Debian packaging are practiced. You don’t need to use all of them. ヒント     There is very extensive documentation in 「Chapter 6. Best Packaging Practices」 in the 「Debian Developer’s Reference」. Please read it. 6.2. debhelper package Although a Debian package can be made by writing a debian/rules script without using the debhelper package, it is impractical to do so. There are too many modern 「Debian Policy」 required features to be addressed, such as application of the proper file     permissions, use of the proper architecture dependent library installation path, insertion of the installation hook scripts, generation of the debug symbol package, generation of package dependency information, generation of the package information files, application of the proper timestamp for reproducible build, etc. Debhelper package provides a set of useful scripts in order to simplify Debian’s packaging workflow and reduce the burden of     package maintainers. When properly used, they will help packagers handle and implement 「Debian Policy」 required features automatically.     The modern Debian packaging workflow can be organized into a simple modular workflow by: * using the dh command to invoke many utility scripts     automatically from the debhelper package, and * configuring their behavior with declarative configuration files in the debian/ directory. You should almost always use debhelper as your package’s build     dependency. This document also assumes that you are using a fairly contemporary version of debhelper to handle packaging works in the following contents. 注記 For debhelper 「compat >= 9」, the dh command exports compiler     flags (CFLAGS, CXXFLAGS, FFLAGS, CPPFLAGS and LDFLAGS) with values as returned by dpkg-buildflags if they are not set previously. (The dh command calls set_buildflags defined in the Debian::Debhelper::Dh_Lib module.) 注記     debhelper(1) changes its behavior with time. Please make sure to read debhelper-compat-upgrade-checklist(7) to understand the situation. 6.3. パッケージ名とバージョン If the upstream source comes as hello-0.9.12.tar.gz, you can take     hello as the upstream source package name and 0.9.12 as the upstream version. There are some limitations for what characters may be used as a     part of the Debian package. The most notable limitation is the prohibition of uppercase letters in the package name. Here is a summary as a set of regular expressions: * Upstream package name (-p): [-+.a-z0-9]{2,}     * Binary package name (-b): [-+.a-z0-9]{2,} * Upstream version (-u): [0-9][-+.:~a-z0-9A-Z]* * Debian revision (-r): [0-9][+.~a-z0-9A-Z]*     See the exact definition in 「Chapter 5 - Control files and their fields」 in the 「Debian Policy Manual」.     You must adjust the package name and upstream version accordingly for the Debian packaging. In order to manage the package name and version information effectively under popular tools such as the aptitude command, it     is a good idea to keep the length of package name to be equal or less than 30 characters; and the total length of version and revision to be equal or less than 14 characters. ^[12]     In order to avoid name collisions, the user visible binary package name should not be chosen from any generic words. If upstream does not use a normal versioning scheme such as 2.30.32 but uses some kind of date such as 11Apr29, a random codename string, or a VCS hash value as part of the version, make sure to remove them from the upstream version. Such information can be recorded in the debian/changelog file. If you need to     invent a version string, use the YYYYMMDD format such as 20110429 as upstream version. This ensures that the dpkg command interprets later versions correctly as upgrades. If you need to ensure a smooth transition to a normal version scheme such as 0.1 in the future, use the 0~YYMMDD format such as 0~110429 as upstream version, instead.     Version strings can be compared using the dpkg command as follows.     $ dpkg --compare-versions ver1 op ver2     バージョンの比較ルールは以下のようにまとめられます: * 文字列は頭から尾へと比較されます。     * 英文字は数字よりも大きいです。 * 数字は整数として比較されます。 * 英文字は ASCII コード順で比較されます。     There are special rules for period (.), plus (+), and tilde (~) characters, as follows.     0.0 < 0.5 < 0.10 < 0.99 < 1 < 1.0~rc1 < 1.0 < 1.0+b1 < 1.0+nmu1 < 1.1 < 2.0 One tricky case occurs when the upstream releases hello-0.9.12-ReleaseCandidate-99.tar.gz as the pre-release of     hello-0.9.12.tar.gz. You can ensure the Debian package upgrade to work properly by renaming the upstream source to hello-0.9.12~rc99.tar.gz. 6.4. ネイティブ Debian パッケージ The non-native Debian package in the Debian source format 「3.0 (quilt)」 is the most normal Debian source package format. The     debian/source/format file should have 「3.0 (quilt)」 in it as described in dpkg-source(1). The above workflow and the following packaging examples always use this format. A native Debian package is the rare Debian binary package format.     It may be used only when the package is useful and valuable only for Debian. Thus, its use is generally discouraged. 注意 A native Debian package is often accidentally built when its     upstream tarball is not accessible from the dpkg-buildpackage command with its correct name package_version.orig.tar.gz . This is a typical newbie mistake caused by making a symlink name with 「-」 instead of the correct one with 「_」.     A native Debian package has no separation between the upstream code and the Debian changes and consists only of the following: * package_version.tar.gz (copy or symlink of package-version     .tar.gz with debian/* files.) * package_version.dsc     If you need to create a native Debian package, create it in the Debian source format 「3.0 (native)」 using dpkg-source(1). ヒント There is no need to create the tarball in advance if the native Debian package format is used. The debian/source/format file     should have 「3.0 (native)」 in it as described in dpkg-source(1) and The debian/source/format file should have the version without the Debian revision (1.0 instead of 1.0-1). Then, the tarball containing is generated when 「dpkg-source -b」 is invoked in the source tree. 6.5. debian/rules file The debian/rules file is the executable script which re-targets the upstream build system to install files in the $(DESTDIR) and     creates the archive file of the generated files as the deb file. The deb file is used for the binary distribution and installed to the system using the dpkg command.     The Debian policy compliant debian/rules file supporting all the required targets can be written as simple as ^[13]: Simple debian/rules:  #!/usr/bin/make -f     #export DH_VERBOSE = 1 %: dh $@     The dh command functions as the sequencer to call all required 「 dh target」 commands at the right moment. ^[14] * dh clean : clean files in the source tree. * dh build : build the source tree * dh build-arch : build the source tree for architecture dependent packages * dh build-indep : build the source tree for architecture independent packages * dh install : install the binary files to $(DESTDIR)     * dh install-arch : install the binary files to $(DESTDIR) for architecture dependent packages * dh install-indep : install the binary files to $(DESTDIR) for architecture independent packages * dh binary : generate the deb file * dh binary-arch : generate the deb file for architecture dependent packages * dh binary-indep : generate the deb file for architecture independent packages     Here, $(DESTDIR) path depends on the build type. * 「DESTDIR=debian/binarypackage/」 for single binary package ^     [15] * 「DESTDIR=debian/tmp/」 for multi binary package     See 「「Customized debian/rules」」 and 「「Variables for debian/ rules」」 for customization. ヒント     Setting 「export DH_VERBOSE = 1」 outputs every command that modifies files on the build system. Also it enables verbose build logs for some build systems. 6.6. debian/control file The debian/control file consists of blocks of meta data separated     by a blank line. Each block of meta data defines the following in this order:     * meta data for the Debian source package * meta data for the Debian binary packages     See 「Chapter 5 - Control files and their fields」 of the 「 Debian Policy Manual」 for the definition of each meta data. 注記     The debmake command sets the debian/control file with 「 Build-Depends: debhelper-compat (= 13)」 to set the debhelper compatibility level. ヒント     If an existing package has lower than debhelper compatibility level 13, probably it’s time to update its packaging. 6.7. debian/changelog file     The debian/changelog file records the Debian package history. * This should be edited using the debchange command (alias dch ). * This defines the upstream package version and the Debian revision in its first line. * The changes need to be documented in the specific, formal, and concise style. + If Debian maintainer modification fixes reported bugs, add 「Closes: #」 to close those bugs. * Even if you are uploading your package by yourself, you must     document all non-trivial user-visible changes such as: + the security related bug fixes. + the user interface changes. * If you are asking your sponsor to upload it, you should document changes more comprehensively, including all packaging related ones, to help reviewing your package. + The sponsor shouldn’t be forced to second guess your thought behind your package. + The sponsor’s time is more valuable than yours. After finishing your packaging and verifying its quality, please execute the 「dch -r」 command and save the finalized debian/     changelog file with the suite normally set to unstable. ^[16] If you are packaging for backports, security updates, LTS, etc., please use the appropriate distribution names instead. The debmake command creates the initial template file with the     upstream package version and the Debian revision. The distribution is set to UNRELEASED to prevent accidental upload to the Debian archive. ヒント     The date string used in the debian/changelog file can be manually generated by the 「LC_ALL=C date -R」 command. ヒント     Use a debian/changelog entry with a version string such as 1.0.1-1~rc1 when you experiment. Then, unclutter such changelog entries into a single entry for the official package. The debian/changelog file is installed in the /usr/share/doc/     binarypackage directory as changelog.Debian.gz by the dh_installchangelogs command.     The upstream changelog is installed in the /usr/share/doc/ binarypackage directory as changelog.gz. The upstream changelog is automatically found by the dh_installchangelogs using the case insensitive match of its file     name to changelog, changes, changelog.txt, changes.txt, history, history.txt, or changelog.md and searched in the ./ doc/ or docs/ directories. 6.8. debian/copyright file Debian takes the copyright and license matters very seriously.     The 「Debian Policy Manual」 enforces having a summary of them in the debian/copyright file in the package. * 「12.5. Copyright information」     * 「2.3. Copyright considerations」 * 「License information」     The debmake command creates the initial debian/copyright template file. * Please double check copyright with the licensecheck(1)     command. * Please format it as a 「machine-readable debian/copyright file (DEP-5)」. Unless specifically requested to be pedantic with the -P option,     the debmake command skips reporting for auto-generated files with permissive licenses to be practical. 注意     The debian/copyright file should be sorted to keep the generic file patterns at the top of the list. See 「「debmake -k」」. 注記     If you find issues with this license checker, please file a bug report to the debmake package with the problematic part of text containing the copyright and license. 6.9. debian/patches/* files     As demonstrated in 「「Step 3 (alternatives): Modification to the upstream source」」, the debian/patches/ directory holds * patch-file-name.patch files providing -p1 patches and     * the series file which which defines how these patches are applied.     See how these files are used in: * 「「dpkg-source -b」」 to build the Debian source package     * 「「dpkg-source -x」」 to extract source files from the Debian source package 注記     Header texts of these patches should conform to 「DEP-3」. 注記     If you want to use VCS tools such as git, gbp and dgit to create and manage these patches after learning basics here, please refer to later in 「10章Packaging with git」. 6.10. debian/source/include-binaries file The 「dpkg-source --commit」 command functions like dquilt but has one advantage over the dquilt command. While the dquilt     command can’t handle modified binary files, the 「dpkg-source --commit」 command detects modified binary files and lists them in the debian/source/include-binaries file to include them in the Debian tarball as a part of the Debian source package. 6.11. debian/watch file     The uscan(1) command downloads the latest upstream version using the debian/watch file. E.g.: Basic debian/watch file:      version=4 https://ftp.gnu.org/gnu/hello/ @PACKAGE@@ANY_VERSION@@ARCHIVE_EXT@ The uscan command may verify the authenticity of the upstream     tarball with optional configuration (see 「「debian/upstream/ signing-key.asc file」」). See uscan(1), 「「アップストリームソフトウェアの新版更新」」, 「     「Fix with Files-Excluded」」, and 「「Manage patch queue with gbp-pq」」 for more. 6.12. debian/upstream/signing-key.asc file     Some packages are signed by a GPG key and their authenticity can be verified using their public GPG key.     For example, 「GNU hello」 can be downloaded via HTTP from https: //ftp.gnu.org/gnu/hello/ . There are sets of files:     * hello-version.tar.gz (upstream source) * hello-version.tar.gz.sig (detached signature)     Let’s pick the latest version set. Download the upstream tarball and its signature.  $ wget https://ftp.gnu.org/gnu/hello/hello-2.9.tar.gz ...     $ wget https://ftp.gnu.org/gnu/hello/hello-2.9.tar.gz.sig ... $ gpg --verify hello-2.9.tar.gz.sig gpg: Signature made Thu 10 Oct 2013 08:49:23 AM JST using DSA key ID 80EE4A00 gpg: Can't check signature: public key not found If you know the public GPG key of the upstream maintainer from     the mailing list, use it as the debian/upstream/signing-key.asc file. Otherwise, use the hkp keyserver and check it via your web of trust. Download public GPG key for the upstream.  $ gpg --keyserver hkp://keys.gnupg.net --recv-key 80EE4A00 gpg: requesting key 80EE4A00 from hkp server keys.gnupg.net gpg: key 80EE4A00: public key "Reuben Thomas " imported gpg: no ultimately trusted keys found     gpg: Total number processed: 1 gpg: imported: 1 $ gpg --verify hello-2.9.tar.gz.sig gpg: Signature made Thu 10 Oct 2013 08:49:23 AM JST using DSA key ID 80EE4A00 gpg: Good signature from "Reuben Thomas " ... Primary key fingerprint: 9297 8852 A62F A5E2 85B2 A174 6808 9F73 80EE 4A00 ヒント     If your network environment blocks access to the HKP port 11371, use 「hkp://keyserver.ubuntu.com:80」 instead. After confirming the key ID 80EE4A00 is a trustworthy one,     download its public key into the debian/upstream/signing-key.asc file. Set public GPG key to debian/upstream/signing-key.asc.      $ gpg --armor --export 80EE4A00 >debian/upstream/signing-key.asc With the above debian/upstream/signing-key.asc file and the     following debian/watch file, the uscan command can verify the authenticity of the upstream tarball after its download. E.g.: Improved debian/watch file with GPG support:      version=4 opts="pgpsigurlmangle=s/$/.sig/" \ https://ftp.gnu.org/gnu/hello/ @PACKAGE@@ANY_VERSION@@ARCHIVE_EXT@ 6.13. debian/salsa-ci.yml file     Install Salsa CI configuration file. See 「「Salsa CI service」」 . 6.14. Other debian/* files Optional configuration files may be added under the debian/     directory. Most of them are to control dh_* commands offered by the debhelper package but there are some for dpkg-source, lintian and gbp commands. ヒント     Even an upstream source without its build system can be packaged just by using these files. See 「「No Makefile (shell, CLI)」」 as an example. The alphabetical list of notable optional debian/binarypackage.*     configuration files listed below provides very powerful means to set the installation path of files. Please note: * The "^-x[01234]" superscript notation that appears in the following list indicates the minimum value for the debmake -x option that generates the associated template file. See 「「 debmake -x」」 or debmake(1) for details. * For a single binary package, the 「binarypackage.」 part of the filename in the list may be removed. * For a multi binary package, a configuration file missing the 「binarypackage」 part of the filename is applied to the first binary package listed in the debian/control. * When there are many binary packages, their configurations can be specified independently by prefixing their name to their configuration filenames such as 「package-1.install」, 「 package-2.install」, etc. * Some template configuration files may not be created by the debmake command. In such cases, you need to create them with an editor. * Some configuration template files generated by the debmake command with an extra .ex suffix need to be activated by removing that suffix. * Unused configuration template files generated by the debmake command should be removed. * Copy configuration template files as needed to the filenames matching their pertinent binary package names. binarypackage.bug-control ^-x3 installed as usr/share/bug/binarypackage/control in binarypackage. See 「「Bug reports」」. binarypackage.bug-presubj ^-x3 installed as usr/share/bug/binarypackage/presubj in binarypackage.

See 「COMPATIBILITY LEVELS」 in debhelper(7). binarypackage.conffiles ^-x3 This optional file is installed into the DEBIAN directory within the binary package while supplimenting it with all the conffiles auto-detected by debhelper. This file is primarily useful for using "special" entries such as the remove-on-upgrade feature from dpkg(1). If the program you’re packaging requires every user to modify the configuration files in the /etc directory, there are two popular ways to arrange for them not to be conffiles, keeping the dpkg command happy and quiet. # Create a symlink under the /etc directory pointing to a file under the /var directory generated by the maintainer scripts. # Create a file generated by the maintainer scripts under the /etc directory. See dh_installdeb(1). binarypackage.config ^-x3 This is the debconf config script used for asking any questions necessary to configure the package.

See dh_installinfo(1). binarypackage.init ^-x4 Installed into etc/init.d/binarypackage in binarypackage. (deprecated) See dh_installinit(1). binarypackage.install ^-x1 List files which should be installed but are not installed by the dh_auto_install command. See dh_install(1) and dh_auto_install(1). binarypackage.links ^-x1     List pairs of source and destination files to be symlinked. Each pair should be put on its own line, with the source and destination separated by whitespace. See dh_link(1). binarypackage.lintian-overrides ^-x3 Installed into usr/share/lintian/overrides/binarypackage in the package build directory. This file is used to suppress erroneous lintian diagnostics. See dh_lintian(1), lintian(1) and 「Lintian User’s Manual 」. binarypackage.maintscript ^-x2 If this optional file exists, debhelper uses this as the template to generate DEBIAN/binarypackage.{pre,post} {inst,rm} files within the binary package while adding 「 -- "$@"」 to the dpkg-maintscript-helper(1) command. See dh_installdeb(1) and 「Chapter 6 - Package maintainer scripts and installation procedure」 in the 「Debian Policy Manual」. manpage.* ^-x3 These are manpage template files generated by the debmake command. Please rename these to appropriate file names and update their contents. Debian Policy requires that each program, utility, and function should have an associated manual page included in the same package. Manual pages are written in nroff (1). If you are new to making a manpage, use manpage.asciidoc or manpage.1 as the starting point. binarypackage.manpages ^-x1 List man pages to be installed. See dh_installman(1). binarypackage.menu (deprecated, no more installed) tech-ctte #741573 decided 「Debian should use .desktop files as appropriate」. Debian menu file installed into usr/share/menu/ binarypackage in binarypackage. See menufile(5) for its format. See dh_installmenu(1). NEWS ^-x3 Installed into usr/share/doc/binarypackage/NEWS.Debian. See dh_installchangelogs(1). patches/* Collection of -p1 patch files which are applied to the upstream source before building the source. No patch files are generated by the debmake command. See dpkg-source(1), 「「quilt setup」」 and 「「Step 3 (alternatives): Modification to the upstream source」」. patches/series ^-x1 The application sequence of the patches/* patch files. binarypackage.preinst ^-x2, binarypackage.postinst ^-x2, binarypackage.prerm ^-x2, binarypackage.postrm ^-x2 If these optional files exist, the corresponding files are installed into the DEBIAN directory within the binary package after enriched by debhelper. Otherwise, these files in the DEBIAN directory within the binary package is generated by debhelper. Whenever possible, simpler binarypackage.maintscript should be used instead. See dh_installdeb(1) and 「Chapter 6 - Package maintainer scripts and installation procedure」 in the 「Debian Policy Manual」. See also debconf-devel(7) and 「3.9.1 Prompting in maintainer scripts」 in the 「Debian Policy Manual」.

This file provides the information specific to the Debian package. See dh_installdocs(1). README.source ^-x1 Installed into the first binary package listed in the debian/control file as usr/share/doc/binarypackage/ README.source. If running 「dpkg-source -x」 on a source package doesn’t produce the source of the package, ready for editing, and allow one to make changes and run dpkg-buildpackage to produce a modified package without taking any additional steps, creating this file is recommended. See 「Debian policy manual section 4.14」. binarypackage.service ^-x3 If this exists, it is installed into lib/systemd/system/ binarypackage.service in binarypackage. See dh_systemd_enable(1), dh_systemd_start(1), and dh_installinit(1). source/format ^-x1 The Debian package format. # Use 「3.0 (quilt)」 to make this non-native package (recommended) # Use 「3.0 (native)」 to make this native package See 「SOURCE PACKAGE FORMATS」 in dpkg-source(1). source/lintian-overrides ^-x3 These file is not installed, but are scanned by the lintian command to provide overrides for the source package. See dh_lintian(1) and lintian(1). source/local-options ^-x1 The dpkg-source command uses this content as its options. Notable options are: # unapply-patches # abort-on-upstream-changes # auto-commit # single-debian-patch This is not included in the generated source package and is meant to be committed to the VCS of the maintainer. See 「FILE FORMATS」 in dpkg-source(1). source/local-patch-header ^-x1 Free form text that is put on top of the automatic patch generated. This is not included in the generated source package and is meant to be committed to the VCS of the maintainer. See 「FILE FORMATS」 in dpkg-source(1). source/options ^-x3 Use source/local-options instead to avoid issues with NMUs.

(deprecated) See dh_installinit(1). upstream/metadata ^-x1 Per-package machine-readable metadata about upstream (DEP-12). See 「Upstream MEtadata GAthered with YAml (UMEGAYA)」. --------------------------------------------------------------------- ^[11] This is the default up to debhelper v13. At debhelper v14,     it warns the default change. After debhelper v15, it will change the default to DESTDIR=debian/tmp/ . ^[12] For more than 90% of packages, the package name is equal or     less than 24 characters; the upstream version is equal or less than 10 characters and the Debian revision is equal or less than 3 characters.     ^[13] The debmake command generates a bit more complicated debian /rules file. But this is the core part. ^[14] This simplicity is available since version 7 of the     debhelper package. This guide assumes the use of debhelper version 13 or newer. ^[15] This is the default up to debhelper v13. At debhelper v14,     it warns the default change. After debhelper v15, it will change the default to DESTDIR=debian/tmp/ .     ^[16] If you are using the vim editor, make sure to save this with the 「:wq」 command. 第7章 Sanitization of the source     There are a few cases which require to sanitize the source to prevent contaminating the generated Debian source package. * Non DFSG contents in the upstream source. + Debian takes software freedom seriously and follows the DFSG. * Extraneous auto-generated contents in the upstream source. + Debian package should rebuild them under the latest     system. * Extraneous VCS contents in the upstream source. + The -i and -I options set in 「「devscripts setup」」 for the dpkg-source(1) command should avoid these. o The -i option is aimed at the non-native Debian package. o The -I is aimed at the native Debian package.     There are several methods to avoid inclusion of undesirable contents. 7.1. Fix with Files-Excluded     This is suitable for avoiding non DFSG contents in the upstream source tarball. * List the files to be removed in the Files-Excluded stanza of the debian/copyright file. * List the URL to download the upstream tarball in the debian/ watch file. * Run the uscan command to download the new upstream tarball.     + Alternatively, use the 「gbp import-orig --uscan --pristine-tar」 command. * mk-origtargz invoked from uscan removes excluded files from the upstream tarball and repack it as a clean tarball. * The resulting tarball has the version number with an additional suffix +dfsg.     See 「COPYRIGHT FILE EXAMPLES」 in mk-origtargz(1). 7.2. Fix with 「debian/rules clean」     This is suitable for avoiding auto-generated files and removes them in the 「debian/rules clean」 target 注記     The 「debian/rules clean」 target is called before the 「 dpkg-source --build」 command by the dpkg-buildpackage command and the 「dpkg-source --build」 command ignores removed files. 7.3. Fix with extend-diff-ignore     This is for the non-native Debian package. The problem of extraneous diffs can be fixed by ignoring changes     made to parts of the source tree by adding the 「 extend-diff-ignore=…​」 line in the debian/source/options file. debian/source/options to exclude the config.sub, config.guess and Makefile files:      # Don't store changes on autogenerated files extend-diff-ignore = "(^|/)(config\.sub|config\.guess|Makefile)$" 注記     This approach always works, even when you can’t remove the file. So it saves you having to make a backup of the unmodified file just to be able to restore it before the next build. ヒント     If the debian/source/local-options file is used instead, you can hide this setting from the generated source package. This may be useful when the local non-standard VCS files interfere with your packaging. 7.4. Fix with tar-ignore     This is for the native Debian package. You can exclude some files in the source tree from the generated     tarball by tweaking the file glob by adding the 「tar-ignore=…​」 lines in the debian/source/options or debian/source/local-options files. 注記 If, for example, the source package of a native package needs files with the file extension .o as a part of the test data, the     setting in 「「devscripts setup」」 is too aggressive. You can work around this problem by dropping the -I option for DEBUILD_DPKG_BUILDPACKAGE_OPTS in 「「devscripts setup」」 while adding the 「tar-ignore=…​」 lines in the debian/source/ local-options file for each package. 7.5. Fix with 「git clean -dfx」 The problem of extraneous contents in the second build can be     avoided by restoring the source tree by committing the source tree to the Git repository before the first build.     You can restore the source tree before the second package build. For example:     $ git reset --hard $ git clean -dfx This works because the dpkg-source command ignores the contents     of the typical VCS files in the source tree with the DEBUILD_DPKG_BUILDPACKAGE_OPTS setting in `"「devscripts setup」 `". ヒント     If the source tree is not managed by a VCS, you should run 「git init; git add -A .; git commit」 before the first build. 第8章 More on packaging     Let’s describe more basics on Debian packaging. 8.1. Package customization All customization data for the Debian source package resides in     the debian/ directory as presented in 「「Step 3: Modification to the template files」」: * The Debian package build system can be customized through the debian/rules file (see 「「Customized debian/rules」」). * The Debian package installation path etc. can be customized     through the addition of configuration files such as package .install and package.docs in the debian/ directory for the dh_* commands from the debhelper package (see 「「Other debian/* files」」). When these are not sufficient to make a good Debian package, -p1 patches of debian/patches/* files are deployed to modify the     upstream source. These are applied in the sequence defined in the debian/patches/series file before building the package as presented in 「「Step 3 (alternatives): Modification to the upstream source」」. You should address the root cause of the Debian packaging problem     by the least invasive way. The generated package shall be more robust for future upgrades in this way. 注記     Send the patch addressing the root cause to the upstream maintainer if it is useful to the upstream. 8.2. Customized debian/rules     Flexible customization of the 「debian/rules file」 is realized by adding appropriate override_dh_* targets and their rules. Whenever some special operation is required for a certain dh_foo     command invoked by the dh command, any automatic execution of it can be overridden by adding the makefile target override_dh_foo in the debian/rules file. The build process may be customized via the upstream provided     interface such as arguments to the standard source build system commands, such as: * configure,     * Makefile, * 「python -m build」, or * Build.PL. If this is the case, you should add the override_dh_auto_build     target with 「dh_auto_build -- arguments」. This ensures passing arguments to the build system after the default parameters that dh_auto_build usually passes. ヒント     Please try not to execute the bare build system commands directly if they are supported by the dh_auto_build command.     See: * 「「Step 3: Modification to the template files」」 for the basic example.     * 「「Note on build system」」 to be reminded of the challenge involving the underlying build system. * 「「マルチアーチ」」 for multiarch customization. * 「「Compiler hardening」」 for hardening customization. 8.3. Variables for debian/rules     Some variable definitions useful for customizing debian/rules can be found in files under /usr/share/dpkg/. Notably: pkg-info.mk Set DEB_SOURCE, DEB_VERSION, DEB_VERSION_EPOCH_UPSTREAM, DEB_VERSION_UPSTREAM_REVISION, DEB_VERSION_UPSTREAM, and DEB_DISTRIBUTION variables obtained from dpkg-parsechangelog (1). (useful for backport support etc..) vendor.mk Set DEB_VENDOR and DEB_PARENT_VENDOR variables; and     dpkg_vendor_derives_from macro obtained from dpkg-vendor(1). (useful for vendor support (Debian, Ubuntu, …​).) architecture.mk Set DEB_HOST_* and DEB_BUILD_* variables obtained from dpkg-architecture(1). buildflags.mk Set CFLAGS, CPPFLAGS, CXXFLAGS, OBJCFLAGS, OBJCXXFLAGS, GCJFLAGS, FFLAGS, FCFLAGS, and LDFLAGS build flags obtained from dpkg-buildflags(1). For example, you can add an extra option to CONFIGURE_FLAGS for     linux-any target architectures by adding the followings to debian /rules: DEB_HOST_ARCH_OS ?= $(shell dpkg-architecture -qDEB_HOST_ARCH_OS) ...     ifeq ($(DEB_HOST_ARCH_OS),linux) CONFIGURE_FLAGS += --enable-wayland endif     See 「「マルチアーチ」」, dpkg-architecture(1) and dpkg-buildflags(1). 8.4. アップストリームソフトウェアの新版更新 When a new upstream release tarball foo-newvwesion.tar.gz is     released, the Debian source package can be updated by invoking commands in the old source tree as: $ uscan     ... foo-newversion.tar.gz downloaded $ uupdate -v newversion ../foo-newversion.tar.gz * The debian/watch file in the old source tree must be a valid one. * This make symlink ../foo_newvwesion.orig.tar.gz pointing to     ../foo-newvwesion.tar.gz. * Files are extracted from ../foo-newvwesion.tar.gz to ../foo- newversion/ * Files are copied from ../foo-oldversion/debian/ to ../foo- newvesion/debian/ . After the above, you should refresh debian/patches/* files (see     「「Manage patch queue with dquilt」」) and update debian/ changelog with the dch(1) command. When 「debian uupdate」 is specified at the end of line in the     debian/watch file, uscan automatically executes uupdate(1) after downloading the tarball. 8.5. Manage patch queue with dquilt     You can add, drop, and refresh debian/patches/* files with dquilt to manage patch queue. * Add a new patch debian/patches/bugname.patch recording the upstream source modification on the file buggy_file as: $ dquilt push -a $ dquilt new bugname.patch $ dquilt add buggy_file $ vim buggy_file ... $ dquilt refresh $ dquilt header -e $ dquilt pop -a * Drop (== disable) an existing patch     + Comment out pertinent line in debian/patches/series + Erase the patch itself (optional) * Refresh debian/patches/* files to make 「dpkg-source -b」 work as expected after updating a Debian package to the new upstream release. $ uscan; uupdate # updating to the new upstream release $ while dquilt push; do dquilt refresh ; done $ dquilt pop -a + If conflicts are encountered with 「dquilt push」 in the above, resolve them and run 「dquilt refresh」 manually for each of them. 8.6. Build commands     Here is a recap of popular low level package build commands. There are many ways to do the same thing. * dpkg-buildpackage = core of package building tool * debuild = dpkg-buildpackage + lintian (build under the     sanitized environment variables) * schroot = core of the Debian chroot environment tool * sbuild = dpkg-buildpackage on custom schroot (build in the chroot) 8.7. Note on sbuild The sbuild(1) command is a wrapper script of dpkg-buildpackage     which builds Debian binary packages in a chroot environment managed by the schroot(1) command. For example, building for Debian unstable suite can be done as:     $ sudo sbuild -d unstable In schroot(1) terminology, this builds a Debian package in a     clean ephemeral chroot 「chroot:unstable-amd64-sbuild」 started as a copy of the clean minimal persistent chroot 「 source:unstable-amd64-sbuild」. This build environment was set up as described in 「「sbuild     setup」」 with 「sbuild-debian-developer-setup -s unstable」 which essentially did the following: $ sudo mkdir -p /srv/chroot/dist-amd64-sbuild     $ sudo sbuild-createchroot unstable /srv/chroot/unstable-amd64-sbuild http://deb.debian.org/debian $ sudo usermod -a -G sbuild $ sudo newgrp - The schroot(1) configuration for unstable-amd64-sbuild was     generated at /etc/schroot/chroot.d/unstable-amd64-sbuild.$suffix : [unstable-amd64-sbuild] description=Debian sid/amd64 autobuilder groups=root,sbuild     root-groups=root,sbuild profile=sbuild type=directory directory=/srv/chroot/unstable-amd64-sbuild union-type=overlay     Here: * The profile defined in the /etc/schroot/sbuild/ directory is used to setup the chroot environment.     * /srv/chroot/unstable-amd64-sbuild directory holds the chroot filesystem. * /etc/sbuild/unstable-amd64-sbuild is symlinked to /srv/chroot /unstable-amd64-sbuild .     You can update this source chroot 「source:unstable-amd64-sbuild 」 by:     $ sudo sbuild-update -udcar unstable     You can log into this source chroot 「 source:unstable-amd64-sbuild」 by:     $ sudo sbuild-shell unstable ヒント     If your source chroot filesystem is missing packages such as libeatmydata1, ccache, and lintian for your needs, you may want to install these by logging into it. 8.8. Special build cases The orig.tar.gz file may need to be uploaded for a Debian     revision other than 0 or 1 under some exceptional cases (e.g., for a security upload). When an essential package becomes a non-essential one (e.g.,     adduser), you need to remove it manually from the existing chroot environment for its use by piuparts. 8.9. Upload orig.tar.gz     When you first upload the package to the archive, you need to include the original orig.tar.gz source, too. If the Debian revision number of the package is either 1 or 0,     this is the default. Otherwise, you must provide the dpkg-buildpackage option -sa to the dpkg-buildpackage command. * dpkg-buildpackage -sa     * debuild -sa * sbuild * For 「gbp buildpackage」, edit the ~/.gbp.conf file. ヒント     On the other hand, the -sd option will force the exclusion of the original orig.tar.gz source. ヒント     Security uploads require including the orig.tar.gz file. 8.10. スキップされたアップロード If you created multiple entries in the debian/changelog while skipping uploads, you must create a proper *_.changes file which     includes all changes since the last upload. This can be done by specifying the dpkg-buildpackage option -v with the last uploaded version, e.g., 1.2. * dpkg-buildpackage -v1.2     * debuild -v1.2 * sbuild --debbuildopts -v1.2 * For gbp buildpackage, edit the ~/.gbp.conf file. 8.11. Bug reports     The reportbug(1) command used for the bug report of binarypackage can be customized by the files in usr/share/bug/binarypackage/.     The dh_bugfiles command installs these files from the template files in the debian/ directory. * debian/binarypackage.bug-control → usr/share/bug/ binarypackage/control + This file contains some directions such as redirecting the bug report to another package. * debian/binarypackage.bug-presubj → usr/share/bug/ binarypackage/presubj     + This file is displayed to the user by the reportbug command. * debian/binarypackage.bug-script → usr/share/bug/binarypackage or usr/share/bug/binarypackage/script + The reportbug command runs this script to generate a template file for the bug report.     See dh_bugfiles(1) and 「reportbug’s Features for Developers ( README.developers)」 ヒント     If you always remind the bug reporter of something or ask them about their situation, use these files to automate it. 第9章上級パッケージング     Let’s describe advanced topics on Debian packaging. 9.1. Historical perspective     Let me oversimplify historical perspective of Debian packaging practices focused on the non-native packaging. Debian was started in 1990s when upstream packages were available     from public FTP sites such as Sunsite. In those early days, Debian packaging used Debian source format currently known as the Debian source format 「1.0」: * The Debian source package ships a set of files for the Debian source package. + package_version.orig.tar.gz : symlink to or copy of the     upstream released file. + package_version-revision.diff.gz : 「One big patch」 for Debian modifications. + package_version-revision.dsc : package description. * Several workaround approaches such as dpatch, dbs, or cdbs were deplyoed to manage multiple topic patches.     The modern Debian source format 「3.0 (quilt)」 was invented around 2008 (see 「ProjectsDebSrc3.0」): * The Debian source package ships a set of files for the Debian source package. + package_version.orig.tar.?z : symlink to or copy of the upstream released file. + package_version-revision.debian.tar.?z : tarball of debian/ for Debian modifications.     o The debian/source/format file contains 「3.0 (quilt) 」. o Optional multiple topic patches are stored in the debian/patches/ directory. + package_version-revision.dsc : package description. * The standarized approach to manage multiple topic patches using quilt(1) is deployed for the Debian source format 「3.0 (quilt)」.     Most Debian packages adopted the Debian source formats 「3.0 (quilt)」 and 「3.0 (native)」. Now, the git(1) is popular with upstream and Debian developers.     The git and its associated tools are important part of the modern Debian packaging workflow. This modern workflow involving git will be mentioned later in 「10章Packaging with git」. 9.2. Current trends     Current Debian packaging practices and their trends are moving target. See: * 「Debian Trends」 — Hints for 「De facto standard」 of Debian practices + Build systems: dh + Debian source format: 「3.0 (quilt)」 + VCS: git     + VCS Hosting: salsa + Rules-Requires-Root: adopted, fakeroot + Copyright format: DEP-5 * 「debhelper-compat-upgrade-checklist(7) manpage」 — Upgrade checklist for debhelper * 「DEP - Debian Enhancement Proposals」 — Formal proposals to enhance Debian     You can also search entire Debian source code data by yourself, too. * 「Debian Sources」 — code search tool     + 「Debian Code Search」 — wiki page describing its usage * 「Debian Code Search」 — another code search tool 9.3. Note on build system Auto-generated files of the build system may be found in the     released upstream tarball. These should be regenerated when Debian package is build. E.g.:     * 「dh $@ --with autoreconf」 should be used in the debian/ rules if Autotools (autoconf + automake) are used. Some modern build system may be able to download required source codes and binary files from arbitrary remote hosts to satisfy     build requirements. Don’t use this download feature. The official Debian package is required to be build only with packages listed in Build-Depends: of the debian/control file. 9.4. Continuous integration The dh_auto_test(1) command is a debhelper command that tries to     automatically run the test suite provided by the upstream developer during the Debian package building process. The autopkgtest(1) command can be used after the Debian package     building process. It tests generated Debian binary packages in the virtual environment using the debian/tests/control RFC822-style metadata file as continuous integration (CI). See: * Documents in the /usr/share/doc/autopkgtest/ directory     * 「4. autopkgtest: Automatic testing for packages」 of the 「 Ubuntu Packaging Guide」     There are several other CI tools on Debian for you to explore. * The Salsa offers 「「Salsa CI service」」.     * The debci package: CI platform on top of the autopkgtest package * The jenkins package: generic CI platform 9.5. Bootstrapping Debian cares about supporting new ports or flavours. The new ports or flavours require bootstrapping operation for the     cross-build of the initial minimal native-building system. In order to avoid build-dependency loops during bootstrapping, the build-dependency needs to be reduced using the DEB_BUILD_PROFILES environment variable.     See Debian wiki: 「BuildProfileSpec」. ヒント     If a core package foo build depends on a package bar with deep build dependency chains but bar is only used in the test target in foo, you can safely mark the bar with in the Build-depends of foo to avoid build loops. 9.6. Compiler hardening     The compiler hardening support spreading for Debian jessie (8.0) demands that we pay extra attention to the packaging.     You should read the following references in detail.     * Debian wiki: 「Hardening」 * Debian wiki: 「Hardening Walkthrough」 The debmake command adds template comments to the debian/rules     file as needed for DEB_BUILD_MAINT_OPTIONS, DEB_CFLAGS_MAINT_APPEND, and DEB_LDFLAGS_MAINT_APPEND (see 「5章 Simple packaging」 and dpkg-buildflags(1)). 9.7. Reproducible build     Here are some recommendations to attain a reproducible build result. * Don’t embed the timestamp based on the system time. * Don’t embed the file path of the build environment. * Use 「dh $@」 in the debian/rules to access the latest debhelper features. * Export the build environment as 「LC_ALL=C.UTF-8」 (see 「「 Build under UTF-8」」).     * Set the timestamp used in the upstream source from the value of the debhelper-provided environment variable $SOURCE_DATE_EPOCH. * Read more at 「ReproducibleBuilds」. + 「ReproducibleBuilds Howto」. + 「ReproducibleBuilds TimestampsProposal」. The control file source-name_source-version_arch.buildinfo     generated by dpkg-genbuildinfo(1) records the build environment. See deb-buildinfo(5) 9.8. Substvar The debian/control file also defines the package dependency in     which the 「variable substitutions mechanism」 (substvar) may be used to free package maintainers from chores of tracking most of the simple package dependency cases. See deb-substvars(5).     The debmake command supports the following substvars: * ${misc:Depends} for all binary packages * ${misc:Pre-Depends} for all multiarch packages * ${shlibs:Depends} for all binary executable and library     packages * ${python:Depends} for all Python packages * ${python3:Depends} for all Python3 packages * ${perl:Depends} for all Perl packages * ${ruby:Depends} for all Ruby packages For the shared library, required libraries found simply by 「     objdump -p /path/to/program | grep NEEDED」 are covered by the shlib substvar. For Python and other interpreters, required modules found simply     looking for lines with 「import」, 「use」, 「require」, etc., are covered by the corresponding substvars.     For other programs which do not deploy their own substvars, the misc substvar covers their dependency.     For POSIX shell programs, there is no easy way to identify the dependency and no substvar covers their dependency. For libraries and modules required via the dynamic loading     mechanism including the 「GObject introspection」 mechanism, there is no easy way to identify the dependency and no substvar covers their dependency. 9.9. Library package Packaging library software requires you to perform much more work     than usual. Here are some reminders for packaging library software: * The library binary package must be named as in 「「Library package name」」. * Debian ships shared libraries such as /usr/lib//lib foo-0.1.so.1.0.0 (see 「「マルチアーチ」」).     * Debian encourages using versioned symbols in the shared library (see 「「Library symbols」」). * Debian doesn’t ship *.la libtool library archive files. * Debian discourages using and shipping *.a static library files.     Before packaging shared library software, see: * 「Chapter 8 - Shared libraries」 of the 「Debian Policy     Manual」 * 「10.2 Libraries」 of the 「Debian Policy Manual」 * 「6.7.2. Libraries」 of the 「Debian Developer’s Reference」     For the historic background study, see: * 「Escaping the Dependency Hell」 ^[17] + This encourages having versioned symbols in the shared     library. * 「Debian Library Packaging guide」 ^[18] + Please read the discussion thread following its announcement, too. 9.10. マルチアーチ Multiarch support for cross-architecture installation of binary packages (particularly i386 and amd64, but also other     combinations) in the dpkg and apt packages introduced in Debian wheezy (7.0, May 2013), demands that we pay extra attention to packaging.     You should read the following references in detail. * Ubuntu wiki (upstream) + 「MultiarchSpec」     * Debian wiki (Debian situation) + 「Debian multiarch support」 + 「Multiarch/Implementation」 The multiarch is enabled by using the value such as     i386-linux-gnu and x86_64-linux-gnu in the install path of shared libraries as /usr/lib//, etc.. * The value required internally by debhelper scripts is implicitly set in themselves. The maintainer doesn’t need to worry. * The value used in override_dh_* target scripts must be explicitly set in the debian/rules file by the maintainer. The value is stored in the $(DEB_HOST_MULTIARCH) variable     in the following debian/rules snippet example: DEB_HOST_MULTIARCH = $(shell dpkg-architecture -qDEB_HOST_MULTIARCH) ... override_dh_install: mkdir -p package1/lib/$(DEB_HOST_MULTIARCH) cp -dR tmp/lib/. package1/lib/$(DEB_HOST_MULTIARCH)     See: * 「「Variables for debian/rules」」     * 「「debmake -b」」 * 「「Package split scenario and examples」」 * 「dpkg-architecture(1) manpage」 9.11. Split of a Debian binary package     For well behaving build systems, the split of a Debian binary package into small ones can be realized as follows. * Create binary package entries for all binary packages in the     debian/control file. * List all file paths (relative to debian/tmp) in the corresponding debian/binarypackage.install files.     Please check examples in this guide:     * 「「Autotools (multi-binary package)」」 (Autotools based) * 「「CMake (multi-binary package)」」 (CMake based) An intuitive and flexible method to create the initial template     debian/control file defining the split of the Debian binary packages is accommodated with the -b option. See 「「debmake -b」 」. 9.12. Package split scenario and examples     Here are some typical multiarch package split scenarios for the following upstream source examples using the debmake command: * a library source libfoo-1.0.tar.gz     * a tool source bar-1.0.tar.gz written in a compiled language * a tool source baz-1.0.tar.gz written in an interpreted language +---------------------------------------------------------------+ |binarypackage| type |Architecture:|Multi-Arch:| パッケージ内容 | |-------------+------+-------------+-----------+----------------| |libfoo1 |lib^* |any |same |共有ライブラリー| | | | | |、同時インストー| | | | | |ル可能 | |-------------+------+-------------+-----------+----------------| |libfoo-dev |dev^* |any |same |共有ライブラリー| | | | | |ヘッダーファイル| | | | | |他、同時インスト| | | | | |ール可能 | |-------------+------+-------------+-----------+----------------| |libfoo-tools |bin^* |any |foreign |実行時サポートプ| | | | | |ログラム、同時イ| | | | | |ンストール不可 | |-------------+------+-------------+-----------+----------------|     |libfoo-doc |doc^* |all |foreign |共有ライブラリー| | | | | |のドキュメンテー| | | | | |ションファイル | |-------------+------+-------------+-----------+----------------| |bar |bin^* |any |foreign |コンパイルされ実| | | | | |行されるプログラ| | | | | |ムファイル、同時| | | | | |インストール不可| |-------------+------+-------------+-----------+----------------| |bar-doc |doc^* |all |foreign |プログラムのドキ| | | | | |ュメンテーション| | | | | |ファイル | |-------------+------+-------------+-----------+----------------| |baz |script|all |foreign |インタープリター| | | | | |で実行されるプロ| | | | | |グラムファイル | +---------------------------------------------------------------+ 9.13. Multiarch library path Debian policy requires to comply with the 「Filesystem Hierarchy     Standard (FHS), version 3.0」, with the exceptions noted in 「 File System Structure」. The most notable exception is the use of /usr/lib//     instead of /usr/lib/ (e.g., /lib32/ and /lib64/) to support a multiarch library. 表9.1 The multiarch library path options +---------------------------------------------------------------+ |Classic path| i386 マルチアーチパス | amd64 マルチアーチパス | |------------+------------------------+-------------------------|     |/lib/ |/lib/i386-linux-gnu/ |/lib/x86_64-linux-gnu/ | |------------+------------------------+-------------------------| |/usr/lib/ |/usr/lib/i386-linux-gnu/|/usr/lib/x86_64-linux-gnu| | | |/ | +---------------------------------------------------------------+ For Autotools based packages under the debhelper package (compat>     =9), this path setting is automatically taken care by the dh_auto_configure command.     For other packages with non-supported build systems, you need to manually adjust the install path as follows. * If 「./configure」 is used in the override_dh_auto_configure target in debian/rules, make sure to replace it with 「     dh_auto_configure --」 while re-targeting the install path from /usr/lib/ to /usr/lib/$(DEB_HOST_MULTIARCH)/. * Replace all occurrences of /usr/lib/ with /usr/lib/*/ in debian/foo.install files. All files installed simultaneously as the multiarch package to     the same file path should have exactly the same file content. You must be careful with differences generated by the data byte order and by the compression algorithm.     The shared library files in the default path /usr/lib/ and /usr/ lib// are loaded automatically.     For shared library files in another path, the GCC option -l must be set by the pkg-config command to make them load properly. 9.14. Multiarch header file path     GCC includes both /usr/include/ and /usr/include// by default on the multiarch Debian system. If the header file is not in those paths, the GCC option -I must     be set by the pkg-config command to make "#include " work properly. 表9.2 The multiarch header file path options +---------------------------------------------------------------+ | Classic path | i386 マルチアーチパス | amd64 マルチアーチパス | |--------------+-----------------------+------------------------| |/usr/include/ |/usr/include/ |/usr/include/ | | |i386-linux-gnu/ |x86_64-linux-gnu/ | |--------------+-----------------------+------------------------|     |/usr/include/ |/usr/include/ |/usr/include/ | |packagename/ |i386-linux-gnu/ |x86_64-linux-gnu/ | | |packagename/ |packagename/ | |--------------+-----------------------+------------------------| |  |/usr/lib/i386-linux-gnu|/usr/lib/ | | |/packagename/ |x86_64-linux-gnu/ | | | |packagename/ | +---------------------------------------------------------------+ The use of the /usr/lib//packagename/ path for the     library files allows the upstream maintainer to use the same install script for the multiatch system with /usr/lib/ and the biarch system with /usr/lib/. ^[19] The use of the file path containing packagename enables having     more than 2 development libraries simultaneously installed on a system. 9.15. Multiarch *.pc file path The pkg-config program is used to retrieve information about     installed libraries in the system. It stores its configuration parameters in the *.pc file and is used for setting the -I and -l options for GCC. 表9.3 The *.pc file path options +---------------------------------------------------------------+ |Classic path | i386 マルチアーチパス | amd64 マルチアーチパス |     |-------------+-----------------------+-------------------------| |/usr/lib/ |/usr/lib/i386-linux-gnu|/usr/lib/x86_64-linux-gnu| |pkgconfig/ |/pkgconfig/ |/pkgconfig/ | +---------------------------------------------------------------+ 9.16. Library symbols The symbols support in dpkg introduced in Debian lenny (5.0, May 2009) helps us to manage the backward ABI compatibility of the     library package with the same package name. The DEBIAN/symbols file in the binary package provides the minimal version associated with each symbol.     An oversimplified method for the library packaging is as follows. * Extract the old DEBIAN/symbols file of the immediate previous binary package with the 「dpkg-deb -e」 command. + Alternatively, the mc command may be used to extract the DEBIAN/symbols file. * Copy it to the debian/binarypackage.symbols file. + If this is the first package, use an empty content file instead. * Build the binary package.     + If the dpkg-gensymbols command warns about some new symbols: o Extract the updated DEBIAN/symbols file with the 「 dpkg-deb -e」 command. o Trim the Debian revision such as -1 in it. o Copy it to the debian/binarypackage.symbols file. o Re-build the binary package. + If the dpkg-gensymbols command does not warn about new symbols: o You are done with the library packaging.     For the details, you should read the following primary references. * 「8.6.3 The symbols system」 of the 「Debian Policy Manual」 * 「dh_makeshlibs(1) manapage」     * 「dpkg-gensymbols(1) manapage」 * 「dpkg-shlibdeps(1) manapage」 * 「deb-symbols(5) manapage」     You should also check: * Debian wiki: 「UsingSymbolsFiles」 * Debian wiki: 「Projects/ImprovedDpkgShlibdeps」     * Debian kde team: 「Working with symbols files」 * 「「Autotools (multi-binary package)」」 * 「「CMake (multi-binary package)」」 ヒント For C++ libraries and other cases where the tracking of symbols     is problematic, follow 「8.6.4 The shlibs system」 of the 「 Debian Policy Manual」, instead. Please make sure to erase the empty debian/binarypackage.symbols file generated by the debmake command. For this case, the DEBIAN/shlibs file is used. 9.17. Library package name Let’s consider that the upstream source tarball of the libfoo     library is updated from libfoo-7.0.tar.gz to libfoo-8.0.tar.gz with a new SONAME major version which affects other packages. The binary library package must be renamed from libfoo7 to lib     foo8 to keep the unstable suite system working for all dependent packages after the upload of the package based on the libfoo-8.0 .tar.gz. 警告 If the binary library package isn’t renamed, many dependent     packages in the unstable suite become broken just after the library upload even if a binNMU upload is requested. The binNMU may not happen immediately after the upload due to several reasons.     The -dev package must follow one of the following naming rules: * Use the unversioned -dev package name: libfoo-dev + This is the typical one for leaf library packages. + Only one version of the library source package is allowed in the archive. o The associated library package needs to be renamed from libfoo7 to libfoo8 to prevent dependency breakage in the unstable suite during the library transition. + This approach should be used if the simple binNMU resolves the library dependency quickly for all affected packages. (ABI change by dropping the deprecated API while keeping the active API unchanged.) + This approach may still be a good idea if manual code updates, etc. can be coordinated and manageable within limited packages. (API change) * Use the versioned -dev package names: libfoo7-dev and libfoo8     -dev + This is typical for many major library packages. + Two versions of the library source packages are allowed simultaneously in the archive. o Make all dependent packages depend on libfoo-dev. o Make both libfoo7-dev and libfoo8-dev provide libfoo -dev. o The source package needs to be renamed as libfoo7-7.0 .tar.gz and libfoo8-8.0.tar.gz respectively from lib foo-?.0.tar.gz. o The package specific install file path including lib foo7 and libfoo8 respectively for header files etc. needs to be chosen to make them co-installable. + Do not use this heavy handed approach, if possible. + This approach should be used if the update of multiple dependent packages require manual code updates, etc. (API change) Otherwise, the affected packages become RC buggy with FTBFS. ヒント     If the data encoding scheme changes (e.g., latin1 to utf-8), the same care as the API change needs to be taken.     See 「「Library package」」. 9.18. Library transition When you package a new library package version which affects other packages, you must file a transition bug report against the     release.debian.org pseudo package using the reportbug command with the ben file and wait for the approval for its upload from the Release Team.     Release team has the 「transition tracker」. See 「Transitions」. 注意     Please make sure to rename binary packages as in 「「Library package name」」. 9.19. binNMU safe A 「binNMU」 is a binary-only non-maintainer upload performed for library transitions etc. In a binNMU upload, only the 「     Architecture: any」 packages are rebuilt with a suffixed version number (e.g. version 2.3.4-3 will become 2.3.4-3+b1). The 「 Architecture: all」 packages are not built. The dependency defined in the debian/control file among binary     packages from the same source package should be safe for the binNMU. This needs attention if there are both 「Architecture: any」 and 「Architecture: all」 packages involved in it. * 「Architecture: any」 package: depends on 「Architecture: any 」 foo package + Depends: foo (= ${binary:Version}) * 「Architecture: any」 package: depends on 「Architecture: all 」 bar package     + Depends: bar (= ${source:Version}) * 「Architecture: all」 package: depends on 「Architecture: any 」 baz package + Depends: baz (>= ${source:Version}), baz (<< $ {source:Version}.0~) 9.20. Debugging information The Debian package is built with the debugging information but     packaged into the binary package after stripping the debugging information as required by 「Chapter 10 - Files」 of the 「Debian Policy Manual」.     See * 「6.7.9. Best practices for debug packages」 of the 「Debian Developer’s Reference」. * 「18.2 Debugging Information in Separate Files」 of the 「 Debugging with gdb」 * 「dh_strip(1) manapage」     * 「strip(1) manapage」 * 「readelf(1) manapage」 * 「objcopy(1) manapage」 * Debian wiki: 「DebugPackage」 * Debian wiki: 「AutomaticDebugPackages」 * Debian debian-devel post: 「Status on automatic debug packages」 (2015-08-15) 9.21. -dbgsym package The debugging information is automatically packaged separately as     the debug package using the dh_strip command with its default behavior. The name of such a debug package normally has the -dbgsym suffix. * The debian/rules file shouldn’t explicitly contain dh_strip.     * Set the Build-Depends to debhelper-compat (>=13) while removing Build-Depends to debhelper in debian/control. 9.22. debconf     The debconf package enables us to configure packages during their installation in 2 main ways: * non-interactively from the debian-installer pre-seeding. * interactively from the menu interface (dialog, gnome, kde, …​)     + the package installation: invoked by the dpkg command + the installed package: invoked by the dpkg-reconfigure command     All user interactions for the package installation must be handled by this debconf system using the following files. * debian/binarypackage.config + This is the debconf config script used for asking any     questions necessary to configure the package. * debian/binarypackage.template + This is the debconf templates file used for asking any questions necessary to configure the package.     These debconf files are called by package configuration scripts in the binary Debian package * DEBIAN/binarypackage.preinst     * DEBIAN/binarypackage.prerm * DEBIAN/binarypackage.postinst * DEBIAN/binarypackage.postrm See dh_installdebconf(1), debconf(7), debconf-devel(7) and 「     3.9.1 Prompting in maintainer scripts」 in the 「Debian Policy Manual」. ---------------------------------------------------------------------     ^[17] This document was written before the introduction of the symbols file. ^[18] The strong preference is to use the SONAME versioned -dev package names over the single -dev package name in 「Chapter 6.     Development (-DEV) packages」, which does not seem to be shared by the former ftp-master (Steve Langasek). This document was written before the introduction of the multiarch system and the symbols file. ^[19] This path is compliant with the FHS. 「Filesystem Hierarchy Standard: /usr/lib : Libraries for programming and packages」     states 「Applications may use a single subdirectory under /usr/ lib. If an application uses a subdirectory, all architecture-dependent data exclusively used by the application must be placed within that subdirectory.」 第10章 Packaging with git Up to 「9章上級パッケージング」, we focused on packaging     operations without using Git or any other VCS. These traditional packaging operations were based on the tarball released by the upstream as mentioned in 「「Historical perspective」」. Currently, the git(1) command is the de-facto platform for the VCS tool and is the essential part of both upstream development     and Debian packaging activities. (See Debian wiki 「Debian git packaging maintainer branch formats and workflows」 for existing VCS workflows.) 注記 Since the non-native Debian source package uses 「diff -u」 as     its backend technology for the maintainer modification, it can’t represent modification involving symlink, file permissions, nor binary data (March 2022 discussion on debian-devel@l.d.o). Please avoid making such maintainer modifications even though these can be recorded in the Git repository. Since VCS workflows are complicated topic and there are many     practice styles, I only touch on some key points with minimal information, here. Salsa is the remote Git repository service with associated tools.     It offers the collaboration platform for Debian packaging activities using a custom GitLab application instance. See: * 「「Salsa repository」」     * 「「Salsa account setup」」 * 「「Salsa CI service」」     There are 2 styles of branch names for the Git repository used for the packaging. See 「「Branch names」」.     There are 2 main usage styles for the Git repository for the packaging. See:     * 「「Patch unapplied Git repository」」 * 「「Patch applied Git repository」」     There are 2 notable Debian packaging tools for the Git repository for the packaging. * gbp(1) and its subcommands: + This is a tool designed to work with 「「Patch unapplied Git repository」」. + See 「「Note on gbp」」. * dgit(1) and its subcommands:     + This is a tool designed to work with both 「「Patch applied Git repository」」 and 「「Patch unapplied Git repository」」. + This contains a tool to upload Debian packages using the dgit server. + See 「「Note on dgit」」. 10.1. Salsa repository It is highly desirable to host Debian source code package on     Salsa. Over 90% of all Debian source code packages are hosted on Salsa. ^[20] The exact VCS repository hosting an existing Debian source code     package can be identified by a metadata field Vcs-* which can be viewed with the apt-cache showsrc command. 10.2. Salsa account setup After signing up for an account on Salsa, make sure that the     following pages have the same e-mail address and GPG keys you have configured to be used with Debian, as well as your SSH key: * https://salsa.debian.org/-/profile/emails     * https://salsa.debian.org/-/user_settings/gpg_keys * https://salsa.debian.org/-/user_settings/ssh_keys 10.3. Salsa CI service     Salsa runs Salsa CI service as an instance of GitLab CI for 「「 Continuous integration」」. For every 「git push」 instances, tests which mimic tests run on     the official Debian package service can be run by setting Salsa CI configuration file 「「debian/salsa-ci.yml file」」 as: --- include:     - https://salsa.debian.org/salsa-ci-team/pipeline/raw/master/recipes/debian.yml # Customizations here 10.4. Branch names     The Git repository for the Debian packaging should have at least 2 branches: * debian-branch to hold the current development work. + old style: master (or debian, main, latest, …​)     + DEP-14 style: debian/sid * upstream-branch to hold the upstream releases. + old style: upstream + DEP-14 style: upstream/latest     In this tutorial, old style branch names are used in examples for simplicity. 注記     This upstream-branch may need to be created using the tarball released by the upstream independent of the upstream Git repository since it tends to contain automatically generated files. The upstream Git repository content can co-exit in the local Git     repository used for the Debian packaging by adding its copy. E.g.:     $ git remote add upstream-git $ git fetch upstream-git master:upstream-master     This allows easy cherry-picking from the upstream Git repository for bug fixes. 10.5. Patch unapplied Git repository     The patch unapplied Git repository can be summarized as: * This seems to be the traditional practice as of 2024. * The source tree matches extracted contents by 「dpkg-source -x --skip-patches」 of the Debian source package. + The upstream source is recorded in the Git repository without changes. + The maintainer modified contents are confined within the debian/* directory. + Maintainer changes to the upstream source are recorded in debian/patches/* files for the Debian source format 「3.0 (quilt)」. * This repository style is useful for all variants of traditional workflows and gdb based workflow: + 「「Step 3: Modification to the template files」」 (no patch) + 「「Patch by 「diff -u」 approach」」     o debian/patches/* files can also be generated using 「 git format-patch」, 「git diff」, or 「gitk」 from git commits in the through-away maintainer modification branch or from the upstream unreleased commits. + 「「Patch by dquilt approach」」 including the last 「 dquilt pop -a」 step + 「「Patch by 「gbp-pq」 approach」」 * Use helper scripts such as dquilt(1) and gbp-pq(1) to manage data in debian/patches/* files. + Add .pc line to the ~/.gitignore file if dquilt is used. + Add unapply-patches and abort-on-upstream-changes lines in the debian/source/local-options file. * Use 「dpkg-source -b」 to build the Debian source package. * Use dput(1) to upload the Debian source package. + Use 「dgit --gbp push-source」 or 「dgit --gbp push」 instead to upload the Debian package via the dgit server (see 「dgit-maint-gbp(7)」). 注記     The debian/source/local-options and debian/source/ local-patch-header files are meant to be recorded by the git command. These aren’t included in the Debian source package. 10.6. Patch applied Git repository     The patch applied Git repository can be summarized as: * The source tree matches extracted contents by 「dpkg-source -x」 of the Debian source package. + The source tree is buildable and the same as what NMU     maintainers see. + The source is recorded in the Git repository with maintainer changes including the debian/ directory. + Maintainer changes to the upstream source are also recorded in debian/patches/* files for the Debian source format 「3.0 (quilt)」.     Use one of workflow styles: * dgit-maint-merge(7) workflow. + Use this if you don’t intend to record topic patches in the Debain source package. + Good enough for packages only with trivial modifications to the upstream. + Only choice for packages with intertwined modification histories to the upstream + Add auto-commit and single-debian-patch lines in the debian/source/local-options file + Use 「git checkout upstream; git pull」 to pull the new upstream commit and use 「git checkout master ; git merge 」 to merge it to the master branch. + Use 「dpkg-source -b」 to build the Debian source package. + Use 「dgit push-source」 or 「dgit push」 for uploading     the Debian package via the dgit server. + See 「「Patch by 「dpkg-source --auto-commit」 approach」 」 for example. * dgit-maint-debrebase(7) workflow. + Use this if you wish to commit maintainer changes to the patch applied Git repository with the same granularity as patches of 「「Patch by 「gbp-pq」 approach」」. + Good for packages with multiple sequenced modifications to the upstream. + Use 「dgit build-source」 to build the Debian source package. + Use 「dgit push-source」 or 「dgit push」 for uploading the Debian package via the dgit server. + Details of this workflow are beyond the scope of this tutorial document. See 「「Note on dgit-maint-debrebase workflow」」 for more. 10.7. Note on gbp     The gbp command is provided by the git-buildpackage package. * This command is designed to manage contents of 「「Patch unapplied Git repository」」 efficiently. * Use 「gbp import-orig」 to import the new upstream tar to the git repository. + The 「--pristine-tar」 option for the 「git import-orig」 command enables storing the upstream tarball in the same git repository. + The 「--uscan」 option as the last argument of the 「gbp import-orig」 command enables downloading and committing the new upstream tarball into the git repository. * Use 「gbp import-dsc」 to import the previous Debian source package to the git repository.     * Use 「gbp dch」 to generate the Debian changelog from the git commit messages. * Use 「gbp buildpackage」 to build the Debian binary package from the git repository. + The sbuild package can be used as its clean chroot build backend either by configuration or adding 「--git-builder ='sbuild -A -s --source-only-changes -v -d unstable'」 * Use 「gbp pull」 to update the debian, upstream and pristine-tar branches safely from the remote repository. * Use 「gbp pq」 to manage quilt patches without using dquilt command. * Use 「gbp clone REPOSITORY_URL」 to clone and set up tracking branches for debian, upstream and pristine-tar. Package history management with the git-buildpackage package is     becoming the standard practice for many Debian maintainers. See more at: * 「Building Debian Packages with git-buildpackage」 * 「4 tips to maintain a “3.0 (quilt)” Debian source package in a VCS」     * The systemd packaging practice documentation on 「Building from source」 * The workflow mentioned in dgit-maint-gbp(7) which enables to use this gbp with dgit 10.8. Note on dgit     The dgit command is provided by the dgit package. * This command is designed to manage contents of 「「Patch applied Git repository」」 efficiently.     + This enables to access the Debian package repository as if it is a git remote repository. * This command supports uploading Debian packages using the dgit server from both 「「Patch unapplied Git repository」」 and 「「Patch applied Git repository」」. The new dgit package offers commands to automate packaging     activities using the git repository as an alternative to still popular gbp-buildpackage. Please read their guide: * dgit-maint-merge(7) — for the Debian source format 「3.0 (quilt)」 package with its changes flowing both ways between the upstream Git repository and the Debian Git repository which are tightly coupled using 「「Patch applied Git repository」」. * dgit-maint-debrebase(7) — for the Debian source format 「3.0 (quilt)」 package with its changes flowing mostly one way     from the upstream Git repository to the Debian Git repository using 「「Patch applied Git repository」」. * dgit-maint-gbp(7) — for the Debian source format 「3.0 (quilt)」 package with its Debian Git repository which is kept usable also for people using gbp-buildpackage(1) using 「「Patch unapplied Git repository」」. * dgit-maint-native(7) — for the Debian source format 「3.0 (native)」 package in the Debian Git repository. (No maintainer changes) The dgit(1) command can push the easy-to-trace change history to     the https://browse.dgit.debian.org/ site and can upload Debian package to the Debian repository properly without using dput(1).     The concept around dgit is beyond this tutorial document. Please start reading relevant information:     * 「dgit: use the Debian archive as a git remote (2015)」 * 「tag2upload (2023)」 10.9. Patch by 「gbp-pq」 approach For 「「Patch unapplied Git repository」」, you can generate     debian/patches/* files using the gbp-pq(1) command from git commits in the through-away patch-queue branch. Unlike dquilt which offers similar functionality as seen 「「     Patch by dquilt approach」」 and 「「Manage patch queue with dquilt」」, gbp-pq doesn’t generate .pc/* files. 10.10. Manage patch queue with gbp-pq     You can add, drop, and refresh debian/patches/* files with gbp-pq to manage patch queue. If the package is managed in 「「Patch unapplied Git repository」     」 using the git-buildpackage package, you can revise the upstream source to fix bug as the maintainer and release a new Debian revision using gbp pq. * Add a new patch recording the upstream source modification on the file buggy_file as: $ git checkout master $ gbp pq import gbp:info: ... imported on 'patch-queue/master $ vim buggy_file ... $ git add buggy_file $ git commit $ gbp pq export gbp:info: On 'patch-queue/master', switching to 'master' gbp:info: Generating patches from git (master..patch-queue/master) $ git add debian/patches/* $ dch -i $ git commit -a -m "Closes: #" $ git tag debian/- * Drop (== disable) an existing patch + Comment out pertinent line in debian/patches/series     + Erase the patch itself (optional) * Refresh debian/patches/* files to make 「dpkg-source -b」 work as expected after updating a Debian package to the new upstream release. $ git checkout master $ gbp pq --force import # ensure patch-queue/master branch gbp:info: ... imported on 'patch-queue/master $ git checkout master $ gbp import-orig --pristine-tar --uscan ... gbp:info: Successfully imported version ?.?.? of ../packagename_?.?.?.orig.tar.gz $ gbp pq rebase ... resolve conflicts and commit to patch-queue/master branch $ gbp pq export gbp:info: On 'patch-queue/master', switching to 'master' gbp:info: Generating patches from git (master..patch-queue/master) $ git add debian/patches $ git commit -m "Update patches" $ dch -v -1 $ git commit -a -m "release -1" $ git tag debian/-1 10.11. gbp import-dscs --debsnap For Debian source packages named 「」 recorded in     the snapshot.debian.org archive, an initial git repository managed in 「「Patch unapplied Git repository」」 with all of the Debian version history can be generated as follows.     $ gbp import-dscs --debsnap --pristine-tar 10.12. Note on dgit-maint-debrebase workflow     Here are some hints around dgit-maint-debrebase(7). ^[21] * Use 「dgit setup-new-tree」 to prepare the local git working repository. * The first maintainer modification commit should contain files only in the debian/ directory excluding files in the debian/ patches directory. * debian/patches/* files are generated from the maintainer modification commit history using the 「dgit quilt-fixup」     command automatically invoked from 「dgit build」 and 「dgit push」. * Use 「git-debrebase new-version 」 to rebase the maintainer modification commit history with automatically updated debian/changelog. * Use 「git-debrebase conclude」 to make a new pseudomerge (== 「git merge -s ours」) to record Debian package with clean ff-history.     See dgit-maint-debrebase(7), dgit(1) and git-debrebase(1) for more. 10.13. Quasi-native Debian packaging     The quasi-native packaging scheme packages a source without the real upstream tarball using the non-native package format. ヒント     Some people promote this quasi-native packaging scheme even for programs written only for Debian since it helps to ease communication with the downstream distros such as Ubuntu for bug fixes etc.     This quasi-native packaging scheme involves 2 preparation steps: * Organize its source tree almost like native Debian package (see 「「ネイティブ Debian パッケージ」」) with debian/* files with a few exceptions: + Make debian/source/format to contain 「3.0 (quilt)」 instead of 「3.0 (native)」 .     + Make debian/changelog to contain version-revision instead of version . * Generate missing upstream tarball preferably without debian/* files. + For Debian source format 「3.0 (quilt)」, removal of files under debian/ directory is an optional action.     The rest is the same as the non-native packaging workflow as written in 「「Packaging workflow」」. Although this can be done in many ways (「「Snapshot upstream     tarball (-d, -t)」」), you can use the Git repository and 「git deborig」 as: $ cd /path/to/ $ dch -r ... set its -, e.g., 1.0-1 $ git tag -s debian/1.0-1     $ git rm -rf debian $ git tag -s upstream/1.0 $ git commit -m upstream/1.0 $ git reset --hard HEAD^ $ git deborig $ sbuild ---------------------------------------------------------------------     ^[20] Use of git.debian.org or alioth.debian.org are deprecated now.     ^[21] I may be incorrect, here. 第11章 Tips Please also read insightful pages linked from 「Notes on Debian」     by Russ Allbery (long time Debian developer) which have best practices for advanced packaging topics. 11.1. Build under UTF-8     The default locale of the build environment is C.     Some programs such as the read function of Python3 change their behavior depending on the locale.     Adding the following code to the debian/rules file ensures building the program under the C.UTF-8 locale.     LC_ALL := C.UTF-8 export LC_ALL 11.2. UTF-8 変換     If upstream documents are encoded in old encoding schemes, converting them to UTF-8 is a good idea.     Use the iconv command in the libc-bin package to convert the encoding of plain text files.     $ iconv -f latin1 -t utf8 foo_in.txt > foo_out.txt     Use w3m(1) to convert from HTML files to UTF-8 plain text files. When you do this, make sure to execute it under UTF-8 locale. $ LC_ALL=C.UTF-8 w3m -o display_charset=UTF-8 \     -cols 70 -dump -no-graph -T text/html \ < foo_in.html > foo_out.txt     Run these scripts in the override_dh_* target of the debian/rules file. 11.3. Hints for Debugging     When you face build problems or core dumps of generated binary programs, you need to resolve them yourself. That’s debug.     This is too deep a topic to describe here. So, let me just list few pointers and hints for some typical debug tools. * Wikipedia: 「core dump」 + 「man core」 + Update the 「/etc/security/limits.conf」 file to include the following: * soft core unlimited + 「ulimit -c unlimited」 in ~/.bashrc + 「ulimit -a」 to check + Press Ctrl-\ or 「kill -ABRT 'PID'」 to make a core dump file * gdb - The GNU Debugger + 「info gdb」 + 「Debugging with GDB」 in /usr/share/doc/gdb-doc/html/gdb /index.html * strace - Trace system calls and signals     + Use strace-graph script found in /usr/share/doc/strace/ examples/ to make a nice tree view + 「man strace」 * ltrace - Trace library calls + 「man ltrace」 * 「sh -n script.sh」 - Syntax check of a Shell script * 「sh -x script.sh」 - Trace a Shell script * 「python3 -m py_compile script.py」 - Syntax check of a Python script * 「python3 -mtrace --trace script.py」 - Trace a Python script * 「perl -I ../libpath -c script.pl」 - Syntax check of a Perl script * 「perl -d:Trace script.pl」 - Trace a Perl script + Install the libterm-readline-gnu-perl package or its equivalent to add input line editing capability with history support. * lsof - List open files by processes + 「man lsof」 ヒント     The script command records console outputs. ヒント     The screen and tmux commands used with the ssh command offer secure and robust remote connection terminals. ヒント     A Python- and Shell-like REPL (=READ + EVAL + PRINT + LOOP) environment for Perl is offered by the reply command from the libreply-perl (new) package and the re.pl command from the libdevel-repl-perl (old) package. ヒント     The rlwrap and rlfe commands add input line editing capability with history support to any interactive commands. E.g. 「rlwrap dash -i'」 . 第12章 Tool usages     Here are some notable tools around Debian packaging. 注記 The description in this section is too terse to be useful for     most of the prospective maintainers. This is the intentional choice of the author. You are highly encouraged to search and read all the pertinent documents associated with the commands used. 注記     Examples here use the gz-compression. The xz-compression may be used instead. 12.1. debdiff     You can compare file contents in two source Debian packages with the debdiff command.     $ debdiff old-package.dsc new-package.dsc     You can also compare file lists in two sets of binary Debian packages with the debdiff command.     $ debdiff old-package.changes new-package.changes これらのコマンドは、ソースパッケージ中でどんな変更をしたのか、バ     イナリーパッケージの中で意図せず削除したり配置を間違えたりしてい ないか、そしてバイナリーパッケージの更新時に不用意な変更をしてい ないかどうか、といった事柄を確認するのに便利です。     Debian now enforces the source-only upload when developing packages. So there may be 2 different *.changes files: * package_version-revision_source.changes for the normal     source-only upload * package_version-revision_arch.changes for the binary upload 12.2. dget     You can download the set of files for the Debian source package with the dget command.     $ dget https://www.example.org/path/to/package_version-rev.dsc 12.3. mk-origtargz You can make the upstream tarball ../foo-newversion.tar.[xg]z     accessible from the Debian source tree as ../foo_newversion .orig.tar.[xg]z. 12.4. origtargz     You can fetch the pre-existing orig tarball of a Debian package from various sources, and unpack it with origtargz command.     This is basically for -2, -3, …​ revisions. 12.5. git deborig If the upstream project is hosted on a Git repository without the official release of tarball, you can generate its orig tarball     from the git repository for use by the Debain source package. Please, execute 「git deborig」 from the root of the checked-out source tree.     This is basically for -1 revisions. 12.6. dpkg-source -b     The 「dpkg-source -b」 command packs the upstream source tree into the Debian source package.     It expects a series of patches in the debian/patches/ directory and their application sequence in debian/patches/series. It is compatible with dquilt (see 「「quilt setup」」) operations     and understands the the patch application status from the existance of .pc/applied-patches.     The dpkg-buildpackage command invokes 「dpkg-source -b」. 12.7. dpkg-source -x The 「dpkg-source -x」 command extracts source tree and applies the patches in the debian/patches/ directory using the sequence     specified in debian/patches/series to the upstream source tree. It also adds .pc/applied-patches. (See 「「Patch applied Git repository」」.) The 「dpkg-source -x --skip-patches」 command extracts source     tree only. It doesn’t add .pc/applied-patches. (See 「「Patch unapplied Git repository」」.)     Both extracted source trees are ready for building Debian binary packages with dpkg-buildpackage, dbuild, sbuild, etc.. 12.8. debc     You should install generated packages with the debc command to test it locally.     $ debc package_version-rev_arch.changes 12.9. piuparts     You should install generated packages with the piuparts command to test it automatically.     $ sudo piuparts package_version-rev_arch.changes 注記     This is a very slow process with remote APT package repository access. 12.10. bts After uploading the package, you will receive bug reports. It is     an important duty of a package maintainer to manage these bugs properly as described in 「5.8. Handling bugs」 of the 「Debian Developer’s Reference」.     The bts command is a handy tool to manage bugs on the 「Debian Bug Tracking System」.     $ bts severity 123123 wishlist , tags -1 pending 第13章 More Examples     There is an old Latin saying: 「fabricando fit faber」 (「 practice makes perfect」). It is highly recommended to practice and experiment with all the     steps of Debian packaging with simple packages. This chapter provides you with many upstream cases for your practice.     This should also serve as introductory examples for many programing topics. * Programing in the POSIX shell, Python3, and C. * Method to create a desktop GUI program launcher with icon graphics. * Conversion of a command from CLI to GUI.     * Conversion of a program to use gettext for internationalization and localization: POSIX shell and C sources. * Overview of many build systems: Makefile, Python, Autotools, and CMake.     Please note that Debian takes a few things seriously: * Free software (a.k.a. Libre software) * Stability and security of OS * Universal OS realized via:     + free choice for upstream sources, + free choice of CPU architectures, and + free choice of UI languages.     The typical packaging example presented in 「5章Simple packaging 」 is the prerequisite for this chapter. Some details are intentionally left vague in the following     sections. Please try to read the pertinent documentation and practice yourself to find them out. ヒント     The best source of a packaging example is the current Debian archive itself. Please use the 「Debian Code Search」 service to find pertinent examples. 13.1. Cherry-pick templates     Here is an example of creating a simple Debian package from a zero content source on an empty directory.     This is a good platform to get all the template files without making a mess in the upstream source tree you are working on.     Let’s assume this empty directory to be debhello-0.1. $ mkdir debhello-0.1 $ tree     . └── debhello-0.1 2 directories, 0 files     Let’s generate the maximum amount of template files.     Let’s also use the 「-p debhello -t -u 0.1 -r 1」 options to make the missing upstream tarball with default -x3 and T options. $ cd /path/to/debhello-0.1     $ debmake -p debhello -t -u 0.1 -r 1 I: set parameters ...     Let’s inspect generated template files. $ cd /path/to $ tree . ├── debhello-0.1 │   └── debian │   ├── README.Debian │   ├── README.source │   ├── changelog │   ├── clean │   ├── control │   ├── copyright │   ├── debhello.bug-control.ex │   ├── debhello.bug-presubj.ex │   ├── debhello.bug-script.ex │   ├── debhello.conffiles.ex │   ├── debhello.cron.d.ex │   ├── debhello.cron.daily.ex │   ├── debhello.cron.hourly.ex │   ├── debhello.cron.monthly.ex │   ├── debhello.cron.weekly.ex │   ├── debhello.default.ex │   ├── debhello.emacsen-install.ex │   ├── debhello.emacsen-remove.ex │   ├── debhello.emacsen-startup.ex │   ├── debhello.lintian-overrides.ex │   ├── debhello.service.ex │   ├── debhello.tmpfile.ex │   ├── dirs │   ├── gbp.conf │   ├── install     │   ├── links │   ├── maintscript.ex │   ├── manpage.1.ex │   ├── manpage.asciidoc.ex │   ├── manpage.md.ex │   ├── manpage.sgml.ex │   ├── manpage.xml.ex │   ├── patches │   │   └── series │   ├── postinst.ex │   ├── postrm.ex │   ├── preinst.ex │   ├── prerm.ex │   ├── rules │   ├── salsa-ci.yml │   ├── source │   │   ├── format │   │   ├── lintian-overrides.ex │   │   ├── local-options.ex │   │   ├── local-patch-header.ex │   │   ├── options.ex │   │   └── patch-header.ex │   ├── tests │   │   └── control │   ├── upstream │   │   └── metadata │   └── watch ├── debhello-0.1.tar.gz └── debhello_0.1.orig.tar.gz -> debhello-0.1.tar.gz 7 directories, 50 files Now you can copy any of these generated template files in the     debhello-0.1/debian/ directory to your package as needed while renaming them as needed. 13.2. No Makefile (shell, CLI)     Here is an example of creating a simple Debian package from a POSIX shell CLI program without its build system.     Let’s assume this upstream tarball to be debhello-0.2.tar.gz.     This type of source has no automated means and files must be installed manually.     For example: $ tar -xzmf debhello-0.2.tar.gz     $ cd debhello-0.2 $ sudo cp scripts/hello /bin/hello ...     Let’s get this source as tar file from a remote site and make it the Debian package. Download debhello-0.2.tar.gz.  $ wget http://www.example.org/download/debhello-0.2.tar.gz ... $ tar -xzmf debhello-0.2.tar.gz $ tree . ├── debhello-0.2 │   ├── README.md     │   ├── data │   │   ├── hello.desktop │   │   └── hello.png │   ├── man │   │   └── hello.1 │   └── scripts │   └── hello └── debhello-0.2.tar.gz 5 directories, 6 files     Here, the POSIX shell script hello is a very simple one. hello (v=0.2).  $ cat debhello-0.2/scripts/hello     #!/bin/sh -e echo "Hello from the shell!" echo "" echo -n "Type Enter to exit this program: " read X     Here, hello.desktop supports the 「Desktop Entry Specification」. hello.desktop (v=0.2).  $ cat debhello-0.2/data/hello.desktop [Desktop Entry] Name=Hello Name[fr]=Bonjour     Comment=Greetings Comment[fr]=Salutations Type=Application Keywords=hello Exec=hello Terminal=true Icon=hello.png Categories=Utility;     Here, hello.png is the icon graphics file. Let’s package this with the debmake command. Here, the -b':sh'     option is used to specify that the generated binary package is a shell script. $ cd /path/to/debhello-0.2 $ debmake -b':sh' -x1 I: set parameters ... I: sanity check of parameters I: pkg="debhello", ver="0.2", rev="1" I: *** start packaging in "debhello-0.2". *** I: provide debhello_0.2.orig.tar.gz for non-native Debian package     I: pwd = "/path/to" I: $ ln -sf debhello-0.2.tar.gz debhello_0.2.orig.tar.gz I: pwd = "/path/to/debhello-0.2" I: parse binary package settings: :sh I: binary package=debhello Type=script / Arch=all M-A=foreign I: analyze the source tree I: build_type = Unknown I: scan source for copyright+license text and file extensions I: 25 %, ext = md ...     Let’s inspect notable template files generated.

Since this is the shell script package, the debmake command sets     「Architecture: all」 and 「Multi-Arch: foreign」. Also, it sets required substvar parameters as 「Depends: ${misc:Depends}」. These are explained in 「6章Basics for packaging」. Since this upstream source lacks the upstream Makefile, that functionality needs to be provided by the maintainer. This upstream source contains only a script file and data files and no     C source files; the build process can be skipped but the install process needs to be implemented. For this case, this is achieved cleanly by adding the debian/install and debian/manpages files without complicating the debian/rules file.     Let’s make this Debian package better as the maintainer. debian/rules (maintainer version, v=0.2):  $ cd /path/to/debhello-0.2 $ vim debian/rules ... hack, hack, hack, ...     $ cat debian/rules #!/usr/bin/make -f export DH_VERBOSE = 1 %: dh $@ debian/control (maintainer version, v=0.2):  $ vim debian/control ... hack, hack, hack, ... $ cat debian/control Source: debhello Section: devel Priority: optional Maintainer: Osamu Aoki Build-Depends: debhelper-compat (= 13)     Standards-Version: 4.6.2 Homepage: https://salsa.debian.org/debian/debmake-doc Rules-Requires-Root: no Package: debhello Architecture: all Multi-Arch: foreign Depends: ${misc:Depends} Description: Simple packaging example for debmake This Debian binary package is an example package.

Autotools (single-binary package) Here is an example of creating a simple Debian package from a     simple C source program using Autotools = Autoconf and Automake ( Makefile.am and configure.ac) as its build system. This source usually comes with the upstream auto-generated Makefile.in and configure files, too. This source can be packaged     using these files as in 「「Makefile.in + configure (single-binary package)」」 with the help of the autotools-dev package. The better alternative is to regenerate these files using the latest Autoconf and Automake packages if the upstream provided     Makefile.am and configure.ac are compatible with the latest version. This is advantageous for porting to new CPU architectures, etc. This can be automated by using the 「--with autoreconf」 option for the dh command.     Let’s assume this upstream tarball to be debhello-1.6.tar.gz.     This type of source is meant to be installed as a non-system file, for example, as: $ tar -xzmf debhello-1.6.tar.gz $ cd debhello-1.6     $ autoreconf -ivf # optional $ ./configure --with-math $ make $ make install     Let’s get the source and make the Debian package.

NAME     debmake - program to make a Debian source package 14.2. SYNOPSIS debmake [-h] [-c | -k] [-n | -a package-version.orig.tar.gz | -d | -t ] [-p package] [-u version] [-r revision] [-z extension] [-b     "binarypackage[:type], …​]" [-e foo@example.org] [-f "firstname lastname"] [-i "buildtool" | -j] [-l license_file] [-m] [-o file] [-q] [-s] [-v] [-w "addon, …​"] [-x [01234]] [-y] [-L] [-P] [-T] 14.3. DESCRIPTION     debmake helps to build a Debian package from the upstream source. Normally, this is done as follows: * The upstream tarball is downloaded as the package-version .tar.gz file. * It is untarred to create many files under the package-version / directory. * debmake is invoked in the package-version/ directory,     possibly without any arguments. * Files in the package-version/debian/ directory are manually adjusted. * dpkg-buildpackage (usually from its wrapper debuild or sbuild ) is invoked in the package-version/ directory to make Debian packages.     Make sure to protect the arguments of the -b, -f, -l, and -w options from shell interference by quoting them properly. 14.3.1. optional arguments: -h, --help show this help message and exit. -c, --copyright scan source for copyright+license text and exit. o -c: simple output style o -cc: normal output style (similar to the debian/copyright file) o -ccc: debug output style -k, --kludge compare the debian/copyright file with the source and exit. The debian/copyright file must be organized to list the generic file patterns before the specific exceptions. o -k: basic output style o -kk: verbose output style -n, --native make a native Debian source package without .orig.tar.gz. This makes a Debian source format 「3.0 (native)」 package. If you are thinking of packaging a Debian-specific source tree with debian/ in it into a native Debian package, please think otherwise. You can use the 「debmake -d -i debuild」 or 「debmake -t -i debuild」 commands to make a Debian non-native package using the Debian source format 「3.0 (quilt)」 The only difference is that the debian/changelog file must use the non-native version scheme: version-revision . The non-native package is more friendly to downstream distributions. -a package-version.tar.gz, --archive package-version.tar.gz use the upstream source tarball directly. (-p, -u, -z: overridden) The upstream tarball may be specified as package_version .orig.tar.gz and tar.gz. For other cases, it may be tar.bz2, or tar.xz. If the specified upstream tarball name contains uppercase letters, the Debian package name is generated by converting them to lowercase letters. If the specified argument is the URL (http://, https://, or ftp://) to the upstream tarball, the upstream tarball is downloaded from the URL using wget or curl. -d, --dist run the 「make dist」 command equivalents first to generate the upstream tarball and use it. The 「debmake -d」 command is designed to run in the package/ directory hosting the upstream VCS with the build system supporting the 「make dist」 command equivalents. (automake/ autoconf, …​) -t, --tar run the 「tar」 command to generate the upstream tarball and use it. The 「debmake -t」 command is designed to run in the package/ directory hosting the upstream VCS. Unless you provide the upstream version with the -u option or with the debian/ changelog file, a snapshot upstream version is generated in the 0\~%y%m%d%H%M format, e.g., 0~1403012359, from the UTC date and time. The generated tarball excludes the debian/ directory found in the upstream VCS. (It also excludes typical VCS directories: .git/, .hg/, .svn/, .CVS/.) -p package, --package package set the Debian package name. -u version, --upstreamversion version set the upstream package version. -r revision, --revision revision set the Debian package revision. -z extension, --targz extension set the tarball type, extension=(tar.gz|tar.bz2|tar.xz). (alias: z, b, x) -b "binarypackage[:type],…​", --binaryspec "binarypackage [:type],…​" set the binary package specs by a comma separated list of binarypackage:type pairs. Here, binarypackage is the binary package name, and the optional type is chosen from the following type values: o bin: C/C++ compiled ELF binary code package (any, foreign) (default, alias: "", i.e., null-string) o data: Data (fonts, graphics, …​) package (all, foreign) (alias: da) o dev: Library development package (any, same) (alias: de) o doc: Documentation package (all, foreign) (alias: do) o lib: Library package (any, same) (alias: l) o perl: Perl script package (all, foreign) (alias: pl)     o python3: Python (version 3) script package (all, foreign) (alias: py3, python, py) o ruby: Ruby script package (all, foreign) (alias: rb) o nodejs: Node.js based JavaScript package (all, foreign) (alias: js) o script: Shell and other interpretted language script package (all, foreign) (alias: sh) The pair values in the parentheses, such as (any, foreign), are the Architecture and Multi-Arch stanza values set in the debian/control file. In many cases, the debmake command makes good guesses for type from binarypackage. If type is not obvious, type is set to bin. Here are examples for typical binary package split scenarios where the upstream Debian source package name is foo: o Generating an executable binary package foo: # 「-b’foo:bin'」, or its short form `-b'-'`", or no -b option o Generating an executable (python3) binary package python3-foo: # 「-b’python3-foo:py'」, or its short form 「 -b’python3-foo'」 o Generating a data package foo: # 「-b’foo:data'」, or its short form 「-b'-:data'」 o Generating a executable binary package foo and a documentation one foo-doc: # 「-b’foo:bin,foo-doc:doc'」, or its short form 「 -b'-:-doc'」 o Generating a executable binary package foo, a library package libfoo1, and a library development package libfoo-dev: # 「-b’foo:bin,libfoo1:lib,libfoo-dev:dev'」 or its short form 「-b'-,libfoo1,libfoo-dev'」 If the source tree contents do not match settings for type, the debmake command warns you. -e foo@example.org, --email foo@example.org set e-mail address. The default is taken from the value of the environment variable $DEBEMAIL. -f "firstname lastname", --fullname "firstname lastname" set the fullname. The default is taken from the value of the environment variable $DEBFULLNAME. -i "buildtool", --invoke "buildtool" invoke "buildtool" at the end of execution. buildtool may be 「dpkg-buildpackage」, 「debuild」, 「sbuild」, etc. The default is not to execute any program. Setting this option automatically sets the --local option. -j, --judge run dpkg-depcheck to judge build dependencies and identify file paths. Log files are in the parent directory. o package.build-dep.log: Log file for dpkg-depcheck. o package.install.log: Log file recording files in the debian/tmp directory. -l "license_file,…​", --license "license_file,…​" add formatted license text to the end of the debian/copyright file holding license scan results. The default is to add COPYING and LICENSE, and license_file needs to list only the additional file names all separated by 「,」. -m, --monoarch force packages to be non-multiarch. -o file, --option file read optional parameters from file. (This is not for everyday use.) The content of file is sourced as the Python code at the end of para.py. For example, the package description can be specified by the following file. para['desc'] = 'program short description' para['desc_long'] = '''\ program long description which you wish to include. . Empty line is space + . You keep going on ... ''' -q, --quitearly quit early before creating files in the debian/ directory. -s, --spec use upstream spec (pyproject.py for Python, etc.) for the package description. -v, --version show version information. -w "addon,…​", --with "addon,…​" add extra arguments to the --with option of the dh(1) command as addon in debian/rules. The addon values are listed all separated by 「,」, e.g., 「 -w "python3,autoreconf"」. For Autotools based packages, autoreconf as addon to run 「 autoreconf -i -v -f」 for every package building is default behavior of the dh(1) command. For Autotools based packages, if they install Python (version 3) programs, setting python3 as addon to the debmake command argument is needed since this is non-obvious. But for pyproject.toml based Python packages, setting python3 as     addon to the debmake command argument is not needed since this is obvious and the debmake command automatically set it to the dh(1) command. -x n, --extra n generate configuration files as templates. (Please note debian/changelog, debian/control, debian/copyright, and debian/rules are bare minimum configuration files to build a Debian binary package.) The number n determines which configuration templates are generated. o -x0: all required configuration template files. (selected option if any of these files already exist) o -x1: all -x0 files + desirable configuration template files with binary package type supports. o -x2: all -x1 files + normal configuration template files with maintainer script supports. o -x3: all -x2 files + optional configuration template files. (default optuin) o -x4: all -x3 files + deprecated configuration template files. Some configuration template files are generated with the extra .ex suffix to ease their removal. To activate these, rename their file names to the ones without the .ex suffix and edit their     contents. Existing configuration files are never overwritten. If you wish to update some of the existing configuration files, please rename them before running the debmake command and manually merge the generated configuration files with the old renamed ones. -y, --yes 「force yes」 for all prompts. (without option: 「ask [Y/n]」 ; doubled option: 「force no」) -L, --local generate configuration files for the local package to fool     lintian(1) checks. -P, --pedantic pedantically check auto-generated files. -T, --tutorial output tutorial comment lines in template files. default when -x3 or -x4 is set. 14.4. EXAMPLES For a well behaving source, you can build a good-for-local-use installable single Debian binary package easily with one command. Test install of such a package generated in this way offers a good alternative to the traditional 「make install」 command     installing into the /usr/local directory since the Debian package can be removed cleanly by the 「dpkg -P '…​'」 command. Here are some examples of how to build such test packages. (These should work in most cases. If the -d option does not work, try the -t option instead.)     For a typical C program source tree packaged with autoconf/ automake:     * debmake -d -i debuild     For a typical Python (version 3) module source tree:     * debmake -s -d -b":python3" -i debuild     For a typical Python (version 3) module in the package-version .tar.gz archive:     * debmake -s -a package-version.tar.gz -b":python3" -i debuild     For a typical Perl module in the package-version.tar.gz archive:     * debmake -a package-version.tar.gz -b":perl" -i debuild 14.5. HELPER PACKAGES     Packaging may require installation of some additional specialty helper packages. * Python (version 3) programs may require the pybuild-plugin-pyproject package. * The Autotools (autoconf + automake) build system may require autotools-dev or dh-autoreconf package.     * Ruby programs may require the gem2deb package. * Node.js based JavaScript programs may require the pkg-js-tools package. * Java programs may require the javahelper package. * Gnome programs may require the gobject-introspection package. * etc. 14.6. CAVEAT Although debmake is meant to provide template files for the package maintainer to work on, actual packaging activities are     often performed without using debmake while referencing only existing similar packages and 「Debian Policy Manual」. All template files generated by debmake are required to be modified manually.     There are 2 positive points for debmake: * debmake helps to write terse packaging tutorial 「Guide for     Debian Maintainers」 (debmake-doc package). * debmake provides short extracted license texts as debian/ copyright in decent accuracy to help license review.     Please double check copyright with the licensecheck(1) command. There are some limitations for what characters may be used as a     part of the Debian package. The most notable limitation is the prohibition of uppercase letters in the package name. Here is a summary as a set of regular expressions: * Upstream package name (-p): [-+.a-z0-9]{2,}     * Binary package name (-b): [-+.a-z0-9]{2,} * Upstream version (-u): [0-9][-+.:~a-z0-9A-Z]* * Debian revision (-r): [0-9][+.~a-z0-9A-Z]*     See the exact definition in 「Chapter 5 - Control files and their fields」 in the 「Debian Policy Manual」. debmake assumes relatively simple packaging cases. So all     programs related to the interpreter are assumed to be 「 Architecture: all」. This is not always true. 14.7. DEBUG     Please report bugs to the debmake package using the reportbug command.     The character set in the environment variable $DEBUG determines the logging output level. * i: main.py logging * p: para.py logging * s: checkdep5.py check_format_style() logging * y: checkdep5.py split_years_name() logging * b: checkdep5.py parse_lines() 1 logging — content_state scan loop: begin-loop * m: checkdep5.py parse_lines() 2 logging — content_state scan loop: after regex match * e: checkdep5.py parse_lines() 3 logging — content_state scan loop: end-loop * a: checkdep5.py parse_lines() 4 logging — print author/     translator section text * f: checkdep5.py check_all_license() 1 logging — input filename for the copyright scan * l: checkdep5.py check_all_license() 2 logging — print license section text * c: checkdep5.py check_all_license() 3 logging — print copyright section text * k: checkdep5.py check_all_license() 4 logging — sort key for debian/copyright stanza * r: sed.py logging * w: cat.py logging * n: kludge.py logging (「debmake -k」)     Use this feature as:     $ DEBUG=ipsybmeaflckrwn debmake ...     See README.developer in the source for more. 14.8.

Shortcut options (-a, -i)     The debmake command offers 2 shortcut options.     * -a : open the upstream tarball * -i : execute script to build the binary package     The example in the above 「5章Simple packaging」 can be done simply as follows.     $ debmake -a package-1.0.tar.gz -i debuild ヒント     A URL such as 「https://www.example.org/DL/package-1.0.tar.gz」 may be used for the -a option. ヒント     A URL such as 「https://arm.koji.fedoraproject.org/packages/ibus/ 1.5.7/3.fc21/src/ibus-1.5.7-3.fc21.src.rpm」 may be used for the -a option, too. 15.2. debmake -b The debmake command with the -b option provides an intuitive and     flexible method to create the initial template debian/control file defining the split of the Debian binary packages with following stanzas: * Package: * Architecture: (e.g. amd64)     * Multi-Arch: (see 「「マルチアーチ」」) * Depends: * Pre-Depends:     The debmake command also sets an appropriate set of substvars used in each pertinent dependency stanza.     Let’s quote the pertinent part from the debmake manpage here. -b "binarypackage[:type],…​", --binaryspec "binarypackage [:type],…​" set the binary package specs by a comma separated list of binarypackage:type pairs. Here, binarypackage is the binary package name, and the optional type is chosen from the following type values: o bin: C/C++ compiled ELF binary code package (any, foreign) (default, alias: "", i.e., null-string) o data: Data (fonts, graphics, …​) package (all, foreign) (alias: da) o dev: Library development package (any, same) (alias: de) o doc: Documentation package (all, foreign) (alias: do) o lib: Library package (any, same) (alias: l) o perl: Perl script package (all, foreign) (alias: pl) o python3: Python (version 3) script package (all, foreign) (alias: py3, python, py) o ruby: Ruby script package (all, foreign) (alias: rb) o nodejs: Node.js based JavaScript package (all, foreign) (alias: js) o script: Shell and other interpretted language script package (all, foreign) (alias: sh) The pair values in the parentheses, such as (any, foreign), are the Architecture and Multi-Arch stanza values set in the debian/control file. In many cases, the debmake command makes good guesses for type from binarypackage. If type is not obvious, type is set to bin.     Here are examples for typical binary package split scenarios where the upstream Debian source package name is foo: o Generating an executable binary package foo: # 「-b’foo:bin'」, or its short form `-b'-'`", or no -b option o Generating an executable (python3) binary package python3-foo: # 「-b’python3-foo:py'」, or its short form 「 -b’python3-foo'」 o Generating a data package foo: # 「-b’foo:data'」, or its short form 「-b'-:data'」 o Generating a executable binary package foo and a documentation one foo-doc: # 「-b’foo:bin,foo-doc:doc'」, or its short form 「 -b'-:-doc'」 o Generating a executable binary package foo, a library package libfoo1, and a library development package libfoo-dev: # 「-b’foo:bin,libfoo1:lib,libfoo-dev:dev'」 or its short form 「-b'-,libfoo1,libfoo-dev'」 If the source tree contents do not match settings for type, the debmake command warns you. 15.3. debmake -cc The debmake command with the -cc option can make a summary of the     copyright and license for the entire source tree to standard output. $ tar -xvzf package-1.0.tar.gz     $ cd package-1.0 $ debmake -cc | less     With the -c option, this provides shorter report. 15.4. Snapshot upstream tarball (-d, -t) This test building scheme is good for the git repository     organized as described in gbp-buildpackage(7) which uses the master, upstream, and pristine-tar branches. The upstream snapshot from the upstream source tree in the     upstream VCS can be made with the -d option if the upstream supports the 「make dist」 equivalence.     $ cd /path/to/upstream-vcs $ debmake -d -i debuild     Alternatively, the same can be made with the -t option if the upstream tarball can be made with the tar command.     $ cd /path/to/upstream-vcs $ debmake -p package -t -i debuild Unless you provide the upstream version with the -u option or     with the debian/changelog file, a snapshot upstream version is generated in the 0~%y%m%d%H%M format, e.g., 0~1403012359, from the UTC date and time. If the upstream VCS is hosted in the package/ directory instead     of the upstream-vcs/ directory, the 「-p package」 can be skipped. If the upstream source tree in the VCS contains the debian/* files, the debmake command with either the -d option or the -t     option combined with the -i option automates the making of a non-native Debian package from the VCS snapshot while using these debian/* files. $ cp -r /path/to/package-0~1403012359/debian/. /path/to/upstream-vcs/debian $ dch     ... update debian/changelog $ git add -A .; git commit -m "vcs with debian/*" $ debmake -t -p package -i debuild This non-native Debian binary package building scheme without the     real upstream tarball is considered as the quasi-native Debian package. See 「「Quasi-native Debian packaging」」. 15.5. debmake -j     This is an experimental feature. The generation of a functioning multi-binary package always     requires more manual work than that of a functioning single binary package. The test build of the source package is the essential part of it.     For example, let’s package the same package-1.0.tar.gz (see 「5章 Simple packaging」) into a multi binary package. * Invoke the debmake command with the -j option for the test building and the report generation. $ debmake -j -a package-1.0.tar.gz * Check the last lines of the package.build-dep.log file to judge build dependencies for Build-Depends. (You do not need to list packages used by debhelper, perl, or fakeroot explicitly in Build-Depends. This technique is useful for the generation of a single binary package, too.) * Check the contents of the package.install.log file to identify the install paths for files to decide how you split them into multiple packages. * Start packaging with the debmake command.     $ rm -rf package-1.0 $ tar -xvzf package-1.0.tar.gz $ cd package-1.0 $ debmake -b"package1:type1, ..." * Update debian/control and debian/binarypackage.install files using the above information. * Update other debian/* files as needed. * Build the Debian package with the debuild command or its equivalent. $ debuild * All binary package entries specified in the debian/ binarypackage.install file are generated as binarypackage_version-revision_arch.deb. 注記 The -j option for the debmake command invokes dpkg-depcheck(1) to run debian/rules under strace(1) to obtain library dependencies.     Unfortunately, this is very slow. If you know the library package dependencies from other sources such as the SPEC file in the source, you may just run the "debmake …​" command without the -j option and run the 「debian/rules install」 command to check the install paths of the generated files. 15.6. debmake -k     This is an experimental feature. When updating a package for the new upstream release, the debmake     command can verify the content of the existing debian/copyright file against the copyright and license situation of the entire updated source tree. $ cd package-vcs     $ gbp import-orig --uscan --pristine-tar ... update source with the new upstream release $ debmake -k | less The 「debmake -k」 command parses the debian/copyright file from the top to the bottom and compares the license of all the     non-binary files in the current package with the license described in the last matching file pattern entry of the debian/ copyright file. When editing the auto-generated debian/copyright file, please     make sure to keep the generic file patterns at the top of the list. ヒント     For all new upstream releases, run the 「debmake -k」 command to ensure that the debian/copyright file is current. 15.7. debmake -P The debmake command invoked with the -P option pedantically     checks auto-generated files for copyright+license text even if they are with permissive license. This option affects not only the content of the debian/copyright     file generated by normal execution, but also the output by the execution with the -k, -c, -cc, and -ccc options. 15.8. debmake -T The debmake command invoked with the -T option additionally     prints verbose tutorial comment lines. The lines marked with ### in the template files are part of the verbose tutorial comment lines. 15.9. debmake -x     The amount of template files generated by the debmake command depends on the -x[01234] option.     * See 「「Cherry-pick templates」」 for cherry-picking of the template files. 注記     None of the existing configuration files are modified by the debmake command.
