Guidelines for creating Manjaro packages

This article aims to assist users creating their own packages using Manjaro optimized devtools, also for submission in Manjaro binary repositories. It covers creation of a PKGBUILD, a package build description file sourced by makepkg to create a binary package from source. If already in possession of a PKGBUILD (see makepkg). For instructions regarding existing rules and ways to improve package quality see Manjaro Packaging Standards.


Packages in Manjaro Linux are built using the makepkg utility and the information stored in a PKGBUILD file. When makepkg is run, it searches for a PKGBUILD in the current directory and follows the instructions therein to either compile or otherwise acquire the required files to be packaged within a package file (pkgname.pkg.tar.xz). The resulting package contains binary files and installation instructions; readily installed with pacman.

An Manjaro package is no more than a tar archive, or 'tarball', compressed using xz, which contains the following files generated by makepkg:

  • The binary files to install.
  • .PKGINFO: contains all the metadata needed by pacman to deal with packages, dependencies, etc.
  • .MTREE: contains hashes and timestamps of the files, which are included in the local database so that pacman can verify the integrity of the package.
  • .INSTALL: an optional file used to execute commands after the install/upgrade/remove stage. (This file is present only if specified in the PKGBUILD.)
  • .Changelog: an optional file kept by the package maintainer documenting the changes of the package. (It is not present in all packages.)


Prerequisite software

First ensure that the necessary tools are installed. The package group base-devel should be sufficient; it includes make and additional tools needed for compiling from source.

# pacman -S base-devel

One of the key tools for building packages is makepkg (provided by pacman) which does the following:

  1. Checks if package dependencies are installed.
  2. Downloads the source file(s) from the specified server(s).
  3. Unpacks the source file(s).
  4. Compiles the software and installs it under a fakeroot environment.
  5. Strips symbols from binaries and libraries.
  6. Generates the package meta file which is included with each package.
  7. Compresses the fakeroot environment into a package file.
  8. Stores the package file in the configured destination directory, which is the present working directory by default.

Download and test the installation

Download the source tarball of the software you want to package, extract it, and follow the author's steps to install the program. Make a note of all commands and/or steps needed to compile and install it. You will be repeating those same commands in the PKGBUILD file.

Most software authors stick to the 3-step build cycle:

make install

This is a good time to make sure the program is working correctly.

Creating a PKGBUILD

When you run makepkg, it will look for a PKGBUILD file in the present working directory. If a PKGBUILD file is found it will download the software's source code and compile it according to the instructions specified in the PKGBUILD file. The instructions must be fully interpretable by the Bash shell. After successful completion, the resulting binaries and metadata of the package (package version and dependencies,) are packed in a pkgname.pkg.tar.xz package file that can be installed with pacman -U <package file>.

To begin with a new package, you should first create an empty working directory, (preferably ~/abs/pkgname), change into that directory, and create a PKGBUILD file. You can either copy the prototype PKGBUILD /usr/share/pacman/PKGBUILD.proto to your working directory or copy a PKGBUILD from a similar package. The latter may be useful if you only need to change a few options.

Defining PKGBUILD variables

Example PKGBUILDs are located in /usr/share/pacman/. An explanation of possible PKGBUILD variables can be found in the PKGBUILD article.

makepkg defines three variables that you should use as part of the build and install process:

This contains the absolute path to the directory where the PKGBUILD file is located. This variable used to be used in combination with /src or /pkg postfixes, but the use of srcdir and pkgdir variables is the modern method. $startdir/src is not guaranteed to be the same as $srcdir, and likewise for $pkgdir. Use of this variable is deprecated and strongly discouraged.
This points to the directory where makepkg extracts or copies all source files.
This points to the directory where makepkg bundles the installed package, which becomes the root directory of your built package.

All of them contain absolute paths, which means, you don't have to worry about your working directory if you use these variables properly.

makepkg, and thus the build() and package() functions, are intended to be non-interactive. Interactive utilities or scripts called in those functions may break makepkg, particularly if it is invoked with build-logging enabled (-l). (See FS13214.)

Apart from the current package Maintainer, there may be previous maintainers listed above as Contributors.

PKGBUILD Functions

There are 5 functions, listed here in the order they are executed if all of them exist. If one does not exist, it is simply skipped.

This does not apply to the package() function, as it is required in every PKGBUILD

The pkgver() function

Beginning with pacman 4.1, you can update the pkgver variable during a makepkg. pkgver() is run right after the sources are fetched and extracted.

This is particularly useful if you are making git/svn/hg/etc. packages, where the build process may remain the same, but the source could be updated every day, even every hour. The old way of doing this was to put the date into the pkgver field which, if the software was not updated, makepkg would still rebuild it thinking the version had changed. Some useful commands for this are git describe, hg identify -ni, etc. Please test these before submitting a PKGBUILD, as a failure in the pkgver() function can stop a build in its tracks.

pkgver cannot contain spaces or hyphens (-). Using sed to correct this is common.

The prepare() function

Pacman 4.1 introduces the prepare() function. In this function, commands that are used to prepare sources for building are run, such as patching. This function is run before the build function and after package extraction. If extraction is skipped (makepkg -e), then prepare() is not run.

(From man PKGBUILD) The function is run in bash -e mode, meaning any command that exits with a non-zero status will cause the function to exit.

The build() function

Now you need to implement the build() function in the PKGBUILD file. This function uses common shell commands in Bash syntax to automatically compile software and create a pkg directory to install the software to. This allows makepkg to package files without having to sift through your filesystem.

The first step in the build() function is to change into the directory created by uncompressing the source tarball. makepkg will change the current directory to srcdir before executing the build(), thus in most common cases the first command will look like this:

cd "$pkgname-$pkgver"

The /usr/share/pacman/PKGBUILD.proto file suggests doing

cd "$srcdir/$pkgname-$pkgver"

instead. Again, as $srcdir is an absolute path, this does not make any difference.

Now, you need to list the same commands you used when you manually compiled the software. The build() function in essence automates everything you did by hand and compiles the software in the fakeroot build environment. If the software you are packaging uses a configure script, it is good practice to use --prefix=/usr when building packages for pacman. A lot of software installs files relative to the /usr/local directory, which should only be done if you are manually building from source. All Arch Linux packages should use the /usr directory. As seen in the /usr/share/pacman/PKGBUILD.proto file, the next two lines often look like this:

./configure --prefix=/usr

If your software does not need to build anything, DO NOT use the build() function. The build() function is not required, but the package() function is.

The check() function

Place for calls to make check and similar testing routines. It is highly recommended to have check() as it helps to make sure software has been built correctly and works fine with its dependencies.

Users who don't need it (and occasionally maintainers who can not fix a package for this to pass) can disable it using !check in PKGBUILD/makepkg options or call makepkg with --nocheck flag.

The package() function

The final step is to put the compiled files in a directory where makepkg can retrieve them to create a package. This by default is the pkg directory—a simple fakeroot environment. The pkg directory replicates the hierarchy of the root file system of the software's installation paths. If you have to manually place files under the root of your filesystem, you should install them in the pkg directory under the same directory structure. For example, if you want to install a file to /usr/bin, it should instead be placed under $pkgdir/usr/bin. Very few install procedures require the user to copy dozens of files manually. Instead, for most software, calling make install will do so. The final line should look like the following in order to correctly install the software in the pkg directory:

make DESTDIR="$pkgdir/" install

It is sometimes the case where DESTDIR is not used in the Makefile; you may need to use prefix instead. If the package is built with autoconf/automake, use DESTDIR; this is what is documented in the manuals. If DESTDIR does not work, try building with make prefix="$pkgdir/usr/" install. If that does not work, you will have to look further into the install commands that are executed by "make <...> install".

In some odd cases, the software expects to be run from a single directory. In such cases, it is wise to simply copy these to $pkgdir/opt.

More often than not, the installation process of the software will create any sub-directories below the pkg directory. If it does not, however, makepkg will generate a lot of errors and you will need to manually create sub-directories by adding the appropriate mkdir -p commands in the build() function before the installation procedure is run.

In old packages, there was no package() function. So, files were put into the pkg directory at the end of the build() function. If package() is not present, build() runs via fakeroot. In new packages, package() is required and runs via fakeroot instead, and build() runs without any special privileges.

makepkg --repackage runs only the package() function, so it creates a *.pkg.* file without compiling the package. This may save time e.g. if you just have changed the depends variable of the package.

The package() function is the only required function in a PKGBUILD. If you must only copy files into their respective directories to install a program, do not put it in the build() function, put that in the package() function.

Testing the PKGBUILD and package

As you are writing the build() function, you will want to test your changes frequently to ensure there are no bugs. You can do this using the makepkg command in the directory containing the PKGBUILD file. With a properly formatted PKGBUILD, makepkg will create a package; with a broken or unfinished PKGBUILD, it will raise an error.

If makepkg finishes successfully, it will place a file named pkgname-pkgver.pkg.tar.xz in your working directory. This package can be installed with the pacman -U command. However, just because a package file was built does not imply that it is fully functional. It might conceivably contain only the directory and no files whatsoever if, for example, a prefix was specified improperly. You can use pacman's query functions to display a list of files contained in the package and the dependencies it requires with pacman -Qlp [package file] and pacman -Qip [package file] respectively.

If the package looks sane, then you are done! However, if you plan on releasing the PKGBUILD file, it is imperative that you check and double-check the contents of the depends array.

Also ensure that the package binaries actually run flawlessly! It is annoying to release a package that contains all necessary files, but crashes because of some obscure configuration option that does not quite work well with the rest of the system. If you are only going to compile packages for your own system, though, you do not need to worry too much about this quality assurance step, as you are the only person suffering from mistakes, after all.

Checking package sanity

After testing package functionality check it for errors using namcap:

$ namcap PKGBUILD
$ namcap <package file name>.pkg.tar.xz

Namcap will:

  1. Check PKGBUILD contents for common errors and package file hierarchy for unnecessary/misplaced files
  2. Scan all ELF files in package using ldd, automatically reporting which packages with required shared libraries are missing from depends and which can be omitted as transitive dependencies
  3. Heuristically search for missing and redundant dependencies

and much more. Get into the habit of checking your packages with namcap to avoid having to fix the simplest mistakes after package submission.

Submitting packages to the AUR

Please read AUR User Guidelines#Submitting packages for a detailed description of the submission process.


  1. Download the source tarball of the software you want to package.
  2. Try compiling the package and installing it into an arbitrary directory.
  3. Copy over the prototype /usr/share/pacman/PKGBUILD.proto and rename it to PKGBUILD in a temporary working directory -- preferably ~/abs/.
  4. Edit the PKGBUILD according to the needs of your package.
  5. Run makepkg and see whether the resulting package is built correctly.
  6. If not, repeat the last two steps.


  • Before you can automate the package building process, you should have done it manually at least once unless you know exactly what you are doing in advance, in which case you would not be reading this in the first place. Unfortunately, although a good bunch of program authors stick to the 3-step build cycle of "./configure; make; make install", this is not always the case, and things can get real ugly if you have to apply patches to make everything work at all. Rule of thumb: If you cannot get the program to compile from the source tarball, and make it install itself to a defined, temporary subdirectory, you do not even need to try packaging it. There is not any magic pixie dust in makepkg that makes source problems go away.
  • In a few cases, the packages are not even available as source and you have to use something like sh to get it to work. You will have to do quite a bit of research (read READMEs, INSTALL instructions, man pages, perhaps ebuilds from Gentoo or other package installers, possibly even the MAKEFILEs or source code) to get it working. In some really bad cases, you have to edit the source files to get it to work at all. However, makepkg needs to be completely autonomous, with no user input. Therefore if you need to edit the makefiles, you may have to bundle a custom patch with the PKGBUILD and install it from inside the prepare() function, or you might have to issue some sed commands from inside the prepare() function.

Create a patch file

Example for individual file

 $ diff -Naur filename.ext.old filename.ext > filename-patchname.diff
 cd "${srcdir}/${pkgname}-${pkgver}"
 patch -uN filename.ext ../filename-patchname.diff || return 1

Example for multiple files

 $ diff -Naur package-ver.old package-ver > package-patchname.diff
 cd "${srcdir}/${pkgname}-${pkgver}"
 patch -uNp1 -i ../${pkgname}-patchname.diff || return 1
