Once +a PKGBUILD is written, the actual package is built using \fBmakepkg\fR and +installed with \fBpacman\fR. + +\fBNOTE:\fR If you have a local copy of the Arch Build System (ABS) tree +on your computer, you can copy the PKGBUILD.proto file to your new package +build directory and edit it from there. To acquire/sync the ABS tree, use +the \fBabs\fR script included with pacman/makepkg. + +.SS Quick PKGBUILD Explanation +For an example of a PKGBUILD, see the \fBEXAMPLE\fR section. + +\fIpkgname\fR defines the package name. It should not contain any uppercase +letters. \fIpkgversion\fR defines the actual package version as given by the +developers of the package. No dashes are allowed. \fIpkgrel\fR allows for +\*(DS-specific changes to the package or corrections to a PKGBUILD +without an upstream version change. The value should be an integer. +\fIpkgdesc\fR is a short one-line description for the package, usually taken +from the project's homepage or manpage. It is preferable to keep the length to +one line for displaying during searches. These four variables are required in +every PKGBUILD. \fIurl\fR is also highly recommended so users can find more +information on the package if needed. + +\fIdepends\fR and \fImakedepends\fR are bash arrays which define the +dependencies of the package. Packages listed in \fImakedepends\fR are required +only for building the package, and not for runtime. \fIdepends\fR is used to +list runtime depends. To build the package using \fBmakepkg\fR, ALL dependencies +must be satisfied. For \fBpacman\fR to install the package, all runtime depends +must be satisfied. + +The \fIbackup\fR array specifies files that should be treated specially +when removing or upgrading packages. See \fBHANDLING CONFIG FILES\fR in +the \fIpacman\fR manpage for more information on this. + +The \fIsource()\fR array tells makepkg which files to download or extract before +compiling begins. The \fImd5sums()\fR array provides md5sums for each of these +files. These are used to validate the integrity of the source files. + +The \fIbuild\fR function is what actually does the work of putting the package +together. Sometimes this is as simple as a configure, make, make install (to +$startdir/pkg). However, some customizations are often needed during the build +process. + +Once your PKGBUILD is created, you can run \fBmakepkg\fR from the build +directory. \fBmakepkg\fR will check dependencies and look for the source files +required to build. If some are missing it will attempt to download them, +provided there is a fully-qualified URL in the \fIsource()\fR array. + +.SS Install/Upgrade/Remove Scripting +Pacman has the ability to store and execute a package-specific script when it +installs, removes, or upgrades a package. This allows a package to "configure +itself" after installation and do the opposite right before it is removed. + +The exact time the script is run varies with each operation: + +.TP +.B pre_install +script is run right before files are extracted. + +.TP +.B post_install +script is run right after files are extracted. + +.TP +.B pre_upgrade +script is run right before files are extracted. + +.TP +.B post_upgrade +script is run after files are extracted. + +.TP +.B pre_remove +script is run right before files are removed. + +.TP +.B post_remove +script is run right after files are removed. + +.P +To use this feature, just create a file (eg, pkgname.install) and put it in +the same directory as the PKGBUILD script. Then use the \fIinstall\fR +directive: + +install=pkgname.install + +The install script does not need to be specified in the \fIsource\fR array. +A template install file is available in your ABS tree (/var/abs/install.proto). + +.SH OPTIONS AND DIRECTIVES +.TP +.B pkgname +The name of the package.

Commonly-used +licenses are typically found in \fI/usr/share/licenses/common\fR. If you +see the package's license there, simply reference it in the license field +(eg, \fBlicense="GPL"\fR). If the package provides a license not found in +\fI/usr/share/licenses/common\fR, then you should include the license in +the package itself and set \fBlicense="custom"\fR or +\fBlicense="custom:LicenseName"\fR.

For example, +one could install all KDE packages by installing the 'kde' group. + +.TP +.B archs \fI(array)\fR +This array defines on which architectures the given package is available. + +.TP +.B backup \fI(array)\fR +A space-delimited array of filenames (without a preceding slash). The +\fIbackup\fR line will be propagated to the package meta-info file for +pacman. This will designate all files listed there to be backed up if this +package is ever removed from a system. See \fBHANDLING CONFIG FILES\fR in +the \fIpacman\fR manpage for more information. + +.TP +.B depends \fI(array)\fR +An array of packages that this package depends on to build and run. Packages +in this list should be surrounded with single quotes and contain at least the +package name. They can also include a version requirement of the form +\fBname<>version\fR, where <> is one of these three comparisons: +\fB>=\fR (greater than equal to), \fB<=\fR (less than or equal to), or +\fB=\fR (equal to). + +.TP +.B makedepends \fI(array)\fR +An array of packages that this package depends on to build, but not at runtime. +Packages in this list should follow the same format as \fIdepends\fR. + +.TP +.B conflicts \fI(array)\fR +An array of packages that will conflict with this package (ie, they cannot both +be installed at the same time). This directive follows the same format as +\fIdepends\fR except you cannot specify versions. + +.TP +.B provides \fI(array)\fR +An array of "virtual provisions" that this package provides. This allows a +package to provide dependencies other than its own package name. For example, +the kernel26beyond package can each provide 'kernel26' which allows packages +to simply depend on 'kernel26' rather than "kernel26 OR kernel26beyond". + +.TP +.B replaces \fI(array)\fR +This is an array of packages that this package should replace, and can be used +to handle renamed/combined packages. For example, if the j2re package gets +renamed to jre, then subsequent 'pacman -Syu' calls will not pick up the +upgrade, due to the differing package names. \fIreplaces\fR handles this. + +.TP +.B options \fI(array)\fR +This array allows you to override some of makepkg's default behaviour +when building packages.

Other lines like "Modified by" are -not allowed. Use the darcs patch comments to mention others if you wish. - -pkgname defines the package name. It should not contain any uppercase letters. -The package version defines the upstream version, while the package release -tracks the Archlinux-specific changes. pkgrel should be an integer, pkgrels -like 5wanda1 are reserved for security updates. There the rule is the -following: If the original package's pkgrel was 4, then increment it once when -you add a security patch, but then use 5wanda1, 5wanda2 and so on. This way -the user can easily upgrade to pkgrel=5 which is in -current. - -pkgdesc is a short one-line description for the package. Usually taken from -the project's homepage or manpage. Try to keep the lenght under 80 chars. - -depends() is a bash array which defines the dependencies of the package. -depends() means the other package is required for building and using the -current one. If the dependency is runtime-only, then use rodepends(), if -buildtime-only then use makedepends(). - -The next line is a special Finclude commands which allows you to inherit -any directive from a PKGBUILD scheme. They can be found in the FST, -under /source/include. The "util" scheme always included, since its -provided functions are used by almost every PKGBUILD.

This means it should be in a foo or foo-extra format, where foo -or foo-extra is a dir under /source in the FST. - -The archs() array defines for which architectures the given package is -available. If it's not available, it means that gensync will skip it when -generating package databases. If you are not able to provide a binary package -for a given arch, don't include that in archs()! For example, no matter if -the package could be compiled in x86_64, if you haven't compiled it yourself, -don't include it. If you're sure it won't be available on a given arch (for -example it's written in x86 asm), then use !arch, for example !x86_64. - -The sha1sums() array can be generated with the makepkg -g command. Its purpose -is to prevent compiling from wrong sources, especially when the build is -automatic. Where it is available you can use signatures(), its goal is that -you don't have to update it manually every time. - -The last line will be added automatically to the end of the PKGBUILD if the -build() function used your $CFLAGS or $CXXFLAGS. This is handy if you want to -cross-compile on a faster machine for a slower architecture. Until the package -doesn't use our $CFLAGS we can't cross-compile it, so please try to avoid -creating "unoptimized" packages. If the package doesn't contain any -architecture-dependent file, then you can add this line manually as makepkg -will not detect this. - -Finally we define a build() function that will build the package. If you don't -want to do anything special, probably you don't have to specify anything, as -the default build() (inherited from util.sh) will fit your needs. Even if you -define a custom build(), probably you can re-use parts of the default build(). -For the list of special functions provided by util.sh and others refer to -the /source/include dir. Again, util.sh is included automatically, but you -have to Finclude the others before using them! - -Once the package is successfully installed into the package root, \fImakepkg\fP -will prepare some documentation.

Required by some broken - packages. -scriptlet Don't skip executing scriptlets even if we're in chroot. -.fi - -.SH What is the process of chrooted build ? - -First, what is chroot? We currently use fakeroot to prevent build() from -modifying the host system, and we use a prefix or DESTDIR directive to install -everything to a directory and not under to the host system. This is good, but -not enough. - -This system lacks of the ability to control the list of installed packages -during the build on the system of a packager, the given compiled package maybe -linked itself to an extra installed library. This way we can't really control -the list of real dependencies. For example if libquicktime is installed from -source on my system, then mplayer or any other program can link itself to that, -and so that depends() will be incorrect. Or if I have the closed source binary -NVidia drivers installed, some programs link tho NVidia's libraries. - -Of course there is a sollution to avoid this, to use a real chroot instead of a -simple fakeroot. What is this means? The followings: - -When starting the build, a core chroot system is installed under /var/chroot. -(Of course you can change this value under /etc/makepkg.conf.) The core system -contains ~60 packages which are must installed to build any package in -a chrooted environment. These packages (for example gcc, kernel-headers, make) -should not be mentioned in makedepends(). 'pacman -Sg core chroot-core -devel-core' should show you the actial list. (We try to change this list rarely -of course.) - -When you start building with makepkg -R, pacman will install these packages to -/var/chroot if necessary. This will produce a fully "clean" Archlinux system, -that consits of base packages only. This /var/chroot is fully separated from -the host system so that this will solve the problems mentioned above. -(Linking to a library installed from source, etc.) - -Here comes the fun part. The packages listed in depends() and makedepends() are -installed to this clean (/var/chroot) system. From this point, this chroot is -capable to build the specified package in it without any unnecessary package -installed, fully separated from the host system. - -After this the chroot should be cleaned up which means the removal of the -installed depends() and makedepends(). This ensures us not to build from -scratch the core chroot. - -This way we can prevent lots of dependency problems and it is even possible to -build packages for a different Archlinux version. This is quite efficent when -building security updates or fixing critical bugs in the -stable tree. - -If the build is failed, the working directory will not be deleted, you can find -it under /var/chroot/var/tmp/fst. Later if you want to clean your chroot -(delete the working directory and remove unnecessary packages) you can use 'makepkg -CR'. - -To activate building in a chroot, you should run makepkg as root at least with -the -R option. - -.SH Package splitting - -Package splitting means moving out a list of specifed files to subpackages (like -libmysql out of mysql) and then defining the properties of subpackages. - -NOTE: if you create several subpackages, maintaining those packages will -require more and more time. Thus, unnecessary splits aren't welcome. -Especially, if you split out a library, then don't move the headers to the -package just to speed up building with a few seconds! - -The \fBsubpkgs()\fP array is to define the pkgnames of the subpackages. From -now all the directives has their subfoo equivalent: -.nf -pkgname -> subpkgs() -pkgdesc -> subdescs() -pkgdesc_localized -> subdescs_localized() -license() -> sublicense() -replaces() -> subreplaces() -groups() -> subgroups() -depends() -> subdepends() -rodepends() -> subrodepends() -removes() -> subremoves() -conflicts() -> subconflicts() -provides() -> subprovides() -backup() -> subbackup() -install -> subinstall() -options -> suboptions() -archs -> subarchs() -.fi - -Also note that bash does not support two-dimensional arrays, so when defining the -array of arrays, then quotes are the major separators and spaces are the minor ones. - -Simple example: -.nf -Add the followings to your bottom of your PKGBUILD -subpkgs=('foo' 'bar') -subdescs=('desc of foo' 'desc of bar') -subdepends=('foodep1 foodep2' 'bardep1 bardep2') -subgroups=('apps' 'apps') -subarchs=('i686 x86_64' 'i686 x86_64') -.fi - -You may define conflicts, replaces and other directives for your subpackages, but -the requirement is only to define these 5 ones. - -The second part is to move some files to the - just defined - subpackages. You -should use the Fsplit command for this at the end of your build() function. You -can read more about Fsplit in the fwmakepkg documentation, but here is a short -example: -.nf - -Fsplit subpkgname usr/share/ - -.fi -This will move the /usr/share dir of the package to the "subpkgname" subpackage. - -NOTE: never use a trailing slash when defining file patterns, especially if you -use wildcards in it! - -.SH "SEE ALSO" -.BR makepkg (8), -.BR pacman (8) -.SH AUTHOR -.nf -Judd Vinet <jvinet@zeroflux.org> -and the Frugalware developers <frugalware-devel@frugalware.org> -.fi |
