DEB (Debian)

Official guides for building Debian packages:

A Debian package can be created by moving into the source code and creating these files and/or directories.

  • debian/ = The top-level directory for the package.

    • changelog = Required. A change log listing the updates for the package release itself, not the program.

    • control = Required. This describes the package name, version, maintainer, dependencies, and more.

    • copyright = Required. The licenses used for the package and source code.

    • install = Optional. A text file listing extra files (not installed by make install) that should be copied into the package.

    • rules = Required. A Makefile that explains how to build and install the program before being packaged. In a default environment setup by the dh_make command this essentially runs ./configure; make; make install in the directory that contains the debian/ directory. The shebang at the top of the file should normally be #!/usr/bin/make -f.

    • patches/ = Optional. Files for patching the source code.

    • {preinst|postinst|prerm|postrm} = Optional. These are executable scripts that run before installation, after installation, before removable, or after removable. [1]

Install the required packaging dependencies.

$ sudo apt-get update
$ sudo apt-get install devscripts dh-make dpkg-dev

Create a working build directory, download the source code, and then run dh_make.

$ mkdir build
$ cd build
$ curl -O http://<URL_TO_SOURCE_CODE>
$ tar -v -x -z -f <PROGRAM_NAME>-<VERSION>.tar.gz
$ dh_make -f ../<PROGRAM_NAME>-<VERSION>.tar.gz

This will create a debian/ directory inside of the source code directory. With a template of all of the files required to build the source code. A copy tarball of the source code is also created as <PROGRAM_NAME>_<VERSION>.orig.tar.gz in the build directory.

The DEB package can now be built.

$ dpkg-buildpackage

After building the package, a new source tarball will be created containing the debian directory: <PROGRAM_NAME>_<VERSION>-<DEB_PACKAGE_RELEASE>.debian.tar.gz. The actual package will be named <PACKAGE_NAME>_<VERSION>-<DEB_PACKAGE_RELEASE>_<ARCHITECTURE>.deb.

Many macros exist for helping to build and install Debian packages.

rule macros:

  • dh_auto_clean = make distclean

  • dh_auto_configure = ./configure with directory options for the specific Debian release.

  • dh_auto_build = make

  • dh_auto_test = make test

  • dh_auto_install =

    make install DESTDIR=/<PATH_TO_>/<PACKAGE>-<VERSION>-revision/debian/<PACKAGE>


RPM (Red Hat)

An RPM is built from a “spec” file. This modified shell script contains all of the information about the program and on how to install and uninstall it. It is used to build the RPM.

Common variables:

  • Name = The name of the program.

    • %{name}

  • Version = The version of the package. Typically this is in the format of X.Y.Z (major.minor.bugfix) or ISO date format (for example, “2016-01-01”).

    • %{version}

  • Release = Start with “1%{?dist}” for the first build of the RPM. Increase the number if the package is ever rebuilt. Start from “1%{?dist}” if a new version of the actual program is being built.

  • Summary = One sentence describing the package. A period is not allowed at the end.

  • BuildRoot = The directory that contains all of the RPM packages. The directory structure under here should mirror the files location in relation to the top-level root “/”. For example, “/bin/bash” would be placed under “$RPM_BUILD_ROOT/bin/bash”.

  • BuildArch = The architecture that the program is meant to run on. This is generally either “x86_64” or “i386.” If the code is not dependent on the CPU (for example: Java programs, shell scripts, documentation, etc.) then “noarch” can be used.

  • Requires = List the RPM packages that are dependencies needed for your program to work.

  • License = The license of the program.

  • URL = A URL link to the program’s or, if that is not available, the developer’s website.

  • Source = A tarball of the source code. It should follow the naming standard of <RPM_NAME>-<RPM_PROGRAM_VERSION>.tar.gz.

Sample SPEC file:

Name: my-first-rpm
Version: 1.0.0
Release: 1%{?dist}
Summary: This is my first RPM
License: GPLv3
URL: http://example.tld/

If you want to build the RPM, simply run:

$ sudo rpmbuild -bb <SPECFILE>.spec

In case you also want to build a source RPM (SRPM) run:

$ sudo rpmbuild -ba <SPECFILE>.spec


  • %description = Provide a description of the program.

  • %prep = Define how to extract the source code for building.

  • %setup =

  • %build = This is where the program is built from the source code.

  • %install = Copy files to a directory structure under %{buildroot} that mirrors where their installed location. The %{buildroot} is the top-level directory of a typical Linux file system hierarchy.

  • %file = These are the files that should be copied over during installation. Permissions can also be set.

    • %attr(<MODE>, <USER>, <GROUP>) = Define this in front of a file or folder to give it custom permissions.



Macros are variables in the RPM spec file that are expanded upon compilation of the RPM.

Some useful macros include:

  • %{patches} = An array of all of the defined patch files.

  • %{sources} = An array of all of the defined source files.



During the creation of an RPM there are a few important directories that can and will be referenced.

  • %{topdir} = The directory that the RPM related files should be located. By default this is set to %{getenv:HOME}/rpmbuild.

  • %{builddir} = The %{_topdir}/BUILD directory. This is where the compilation of the program should take place.

  • %{_sourcedir} = The %{_topdir}/SOURCES directory. This is where patches, service files, and source code can be stored.

  • %{_specdir} = The %{_topdir}/SPECS directory. This is where the SPEC file for the RPM should be stored.

  • %{_srcrpmdir} = The %{_topdir}/SRPMS directory. This is where the optional source RPM will be compiled and stored to.

  • %{buildroot} = The %{_topdir}/BUILDROOT directory. This is the file system hierarchy of where the RPM files will actually be installed to. This is also set to the $RPM_BUILD_ROOT shell variable.


Users and Groups

Creating a user or group can be done one of two ways.

  • Dynamically = Let the system decide what user identification number (UID) and group ID (GID) to use.

  • Static = Specify a specific UID or GID number to use. This is useful for keeping permissions identical on multiple platforms.

The Fedora Project recommends using these standardized blocks of code to accomplish these methods. [7]


Requires(pre): shadow-utils
getent group <GROUP_NAME> >/dev/null || groupadd -r <GROUP_NAME>
getent passwd <USER_NAME> >/dev/null || \
    useradd -r -g <GROUP_NAME> -s /sbin/nologin \
exit 0


Requires(pre): shadow-utils
getent group <GROUP_NAME> >/dev/null || groupadd -f -g <GID> -r <GROUP_NAME>
if ! getent passwd <USER_NAME> >/dev/null ; then
    if ! getent passwd <UID> >/dev/null ; then
      useradd -r -u <UID> -g <GROUP_NAME> -s /sbin/nologin -c "Useful comment about the purpose of this account" <USER_NAME>
      useradd -r -g <GROUP_NAME> -s /sbin/nologin -c "<USER_DESCRIPTION>" <USER_NAME>
exit 0


Some applications may require patches to work properly. Patches should be stored in the SOURCES directories. At the beginning of the spec file, where the name and version information is defined, patch file names can also be defined.




Patch0: php-fpm_listen_port.patch
Patch1: php_memory_limit.patch

These patches can then be referenced in the %setup phase (after %prep and before %build%).

%setup -q

A patched file can be created using the diff command.


If multiple files in a directory have been patched, a more comprehensive patch file can be made.


In the spec file, the %patch macro can be used. The -p1 argument strips off the top-level directory of the patch’s path.


%patch0 -p1
%patch1 -p1

Example patch file:

--- d20-1.0.0_patched/src/dice.h
+++ d20-1.0.0/src/dice.h

A patch can also be made without the %patch macro by specifying the location of the patch file.

patch < %{_sourcedir}/<FILE_NAME>



Error Messages

  • The custom_macro macro does not exist. Find and install it to /usr/lib/rpm/macros.d/.

  • Alternatively, if the message complains about a native macro instead, it could be used in the wrong section.

$ rpmbuild
+ echo foo bar
+ %custom_macro
/var/tmp/rpm-tmp.0Sev9I: line 324: fg: no job control
error: Bad exit status from /var/tmp/rpm-tmp.0Sev9I (%prep)


PKGBUILD (Arch Linux)

Arch Linux packages are design to be simple and easy to create. A PKGBUILD file is compressed with a software’s contents into a XZ tarball. This can contain either the source code or compiled program.

Required Variables:

  • pkgname = Name of the software.

  • pkgver = Version of the software.

  • pkgrel = Version of the package (only increase if the PKGBUILD file has been modified and not the software).

  • arch = The architecture the software is built for. Any architecture that applies should be defined. Valid options: x86_64, i686, arm (armv5), armv6h, armv7h, aarch64 (armv8 64-bit), or any.

Optional Variables:

  • pkgdesc = A brief description of the software.

  • url = The URL of the software’s website.

  • license = The license of the software. Valid options: GPL, BSD, MIT, Apache, etc.

  • depends = List other package version dependencies.

  • optdepends = List optional dependencies and a brief description.

  • makedepends = List packages required to build the software from source.

  • provides = List tools that are provided by the package but do not necessarily have file names.

  • conflicts = List any conflicting packages.

  • replaces = List packages that this software should replace.




  • build()

    • For building the software, PKGBUILD will need to move into the directory that the XZ tarball was extracted to. This is automatically generated as the “srcdir” variable. In most situations this should be the package name and version separated by a dash.

      $ cd "${srcdir}"


      $ cd "${pkgname}-${pkgver}"
  • package()

    • These are the steps to copy and/or modify files from the “srcdir” to be placed in the “pkgdir” to represent where they will be installed on an end-user’s system. This acts as the top-level directory of a Linux file system hierarchy.

      $ cd "${pkgdir}"
    • An example of installing compiled source code using a Make file.

      $ make DESTDIR="${pkgdir}" install


AUR Submission

The Arch Linux User (AUR) repository allows developers to easily upload their own packages. Here are the steps on how to submit a new package to the AUR.

SSH Key Pair

Create a unique SSH key pair to use for interacting with the AUR.

$ ssh-keygen -t ed25519 -b 4096 -f ~/.ssh/aur
$ vim ~/.ssh/config
  IdentityFile ~/.ssh/aur
  User aur

Create the AUR Git Repository

Clone a repository with the desired AUR package name. Once files are committed and pushed, this package will be instantly available on the AUR.

$ git clone ssh://<NEW_AUR_PACKAGE_NAME>.git


Every AUR git repository needs to contain at least 2 files:

  • PKGBUILD = The PKGBUILD explains how to download and build the source code.

  • .SRCINFO = Information about what packages the PKGBUILD will provide. Generate this by running makepkg --printsrcinfo > .SRCINFO.

    • Every time the PKGBUILD metadata has been updated, this file needs to be regenerated and committed to the git repository.

Optional files:

  • .gitignore = Ignore build files and directories such as pkg and src.

  • LICENSE = The license for the PKGBUILD. This is generally the same as the software that it builds.

There should not be any binary or source code hosted in the AUR git repository.
