Packaging Debian
 | 
						|
================
 | 
						|
 | 
						|
(Tested on Ubuntu 14.04, 16.04, 17.10, 18.04, Debian jessie, stretch and
 | 
						|
buster.)
 | 
						|
 | 
						|
1. Install the Debian packaging tools:
 | 
						|
 | 
						|
   .. code-block:: shell
 | 
						|
 | 
						|
      sudo apt install fakeroot debhelper devscripts
 | 
						|
 | 
						|
2. Checkout FRR under an **unprivileged** user account:
 | 
						|
 | 
						|
   .. code-block:: shell
 | 
						|
 | 
						|
      git clone https://github.com/frrouting/frr.git frr
 | 
						|
      cd frr
 | 
						|
 | 
						|
   If you wish to build a package for a branch other than master:
 | 
						|
 | 
						|
   .. code-block:: shell
 | 
						|
 | 
						|
      git checkout <branch>
 | 
						|
 | 
						|
3. Install build dependencies using the  `mk-build-deps` tool from the
 | 
						|
   `devscripts` package:
 | 
						|
 | 
						|
   .. code-block:: shell
 | 
						|
 | 
						|
      sudo mk-build-deps --install debian/control
 | 
						|
 | 
						|
   Alternatively, you can manually install build dependencies for your
 | 
						|
   platform as outlined in :ref:`building`.
 | 
						|
 | 
						|
4. Run ``tools/tarsource.sh -V``:
 | 
						|
 | 
						|
   .. code-block:: shell
 | 
						|
 | 
						|
      ./tools/tarsource.sh -V
 | 
						|
 | 
						|
   This script sets up the ``debian/changelog-auto`` file with proper version
 | 
						|
   information.
 | 
						|
 | 
						|
5. (optional) Append a distribution identifier if needed (see below under
 | 
						|
   :ref:`multi-dist`.)
 | 
						|
 | 
						|
6. Build Debian Package:
 | 
						|
 | 
						|
   .. code-block:: shell
 | 
						|
 | 
						|
      dpkg-buildpackage $options
 | 
						|
 | 
						|
   Where `$options` may contain any or all of the following items:
 | 
						|
 | 
						|
   * build profiles specified with ``-P``, e.g.
 | 
						|
     ``-Ppkg.frr.nortrlib,pkg.frr.nosystemd``.
 | 
						|
     Multiple values are separated by commas and there must not be a space
 | 
						|
     after the ``-P``.
 | 
						|
 | 
						|
     The following build profiles are currently available:
 | 
						|
 | 
						|
     +----------------+-------------------+-----------------------------------------+
 | 
						|
     | Profile        | Negation          | Effect                                  |
 | 
						|
     +================+===================+=========================================+
 | 
						|
     | pkg.frr.rtrlib | pkg.frr.nortrlib  | builds frr-rpki-rtrlib package (or not) |
 | 
						|
     +----------------+-------------------+-----------------------------------------+
 | 
						|
     | n/a            | pkg.frr.nosystemd | removes libsystemd dependency and       |
 | 
						|
     |                |                   | disables unit file installation         |
 | 
						|
     +----------------+-------------------+-----------------------------------------+
 | 
						|
 | 
						|
     .. note::
 | 
						|
 | 
						|
        The ``pkg.frr.nosystemd`` option is only intended to support Ubuntu
 | 
						|
        14.04 (and should be enabled when building for that.)
 | 
						|
 | 
						|
   * the ``-uc -us`` options to disable signing the packages with your GPG key
 | 
						|
 | 
						|
     (git builds of the `master` or `stable/X.X` branches won't be signed by
 | 
						|
     default since their target release is set to ``UNRELEASED``.)
 | 
						|
 | 
						|
7. Done!
 | 
						|
 | 
						|
   If all worked correctly, then you should end up with the Debian packages in
 | 
						|
   the parent directory of where `debuild` ran.  If distributed, please make sure
 | 
						|
   you distribute it together with the sources (``frr_*.orig.tar.xz``,
 | 
						|
   ``frr_*.debian.tar.xz`` and ``frr_*.dsc``)
 | 
						|
 | 
						|
.. note::
 | 
						|
 | 
						|
   A package created from `master` or `stable/X.X` is slightly different from
 | 
						|
   a package created from the `debian` branch.  The changelog for the former
 | 
						|
   is autogenerated and sets the Debian revision to ``-0``, which causes an
 | 
						|
   intentional lintian warning.  The `debian` branch on the other hand has
 | 
						|
   a manually maintained changelog that contains proper Debian release
 | 
						|
   versioning.
 | 
						|
 | 
						|
   Furthermore, official Debian packages are built in ``3.0 (quilt)`` format
 | 
						|
   with an "orig" tarball and a "debian" tarball.  These tarballs are created
 | 
						|
   by the ``tarsource.sh`` tool on any branch.  The git repository however
 | 
						|
   contains a ``3.0 (git)`` source format specifier to easily allow direct
 | 
						|
   git builds.
 | 
						|
 | 
						|
 | 
						|
.. _multi-dist:
 | 
						|
 | 
						|
Multi-Distribution builds
 | 
						|
=========================
 | 
						|
 | 
						|
You can optionally append a distribution identifier in case you want to
 | 
						|
make multiple versions of the package available in the same repository.
 | 
						|
Do the following after creating the changelog with `tarsource.sh`:
 | 
						|
 | 
						|
.. code-block:: shell
 | 
						|
 | 
						|
   dch -l '~deb8u' 'build for Debian 8 (jessie)'
 | 
						|
   dch -l '~deb9u' 'build for Debian 9 (stretch)'
 | 
						|
   dch -l '~ubuntu14.04.' 'build for Ubuntu 14.04 (trusty)'
 | 
						|
   dch -l '~ubuntu16.04.' 'build for Ubuntu 16.04 (xenial)'
 | 
						|
   dch -l '~ubuntu18.04.' 'build for Ubuntu 18.04 (bionic)'
 | 
						|
 | 
						|
Between building packages for specific distributions, the only difference
 | 
						|
in the package itself lies in the automatically generated shared library
 | 
						|
dependencies, e.g. libjson-c2 or libjson-c3.  This means that the
 | 
						|
architecture independent packages should **not** have a suffix appended.
 | 
						|
Also, the current Debian testing/unstable releases should not have any suffix
 | 
						|
appended.
 | 
						|
 | 
						|
For example, at the end of 2018 (i.e. ``buster``/Debian 10 is the current
 | 
						|
"testing" release), the following is a complete list of `.deb` files for
 | 
						|
Debian 8, 9 and 10 packages for FRR 6.0.1-1 with RPKI support::
 | 
						|
 | 
						|
   frr_6.0.1-1_amd64.deb
 | 
						|
   frr_6.0.1-1~deb8u1_amd64.deb
 | 
						|
   frr_6.0.1-1~deb9u1_amd64.deb
 | 
						|
   frr-dbg_6.0.1-1_amd64.deb
 | 
						|
   frr-dbg_6.0.1-1~deb8u1_amd64.deb
 | 
						|
   frr-dbg_6.0.1-1~deb9u1_amd64.deb
 | 
						|
   frr-rpki-rtrlib_6.0.1-1_amd64.deb
 | 
						|
   frr-rpki-rtrlib_6.0.1-1~deb8u1_amd64.deb
 | 
						|
   frr-rpki-rtrlib_6.0.1-1~deb9u1_amd64.deb
 | 
						|
   frr-doc_6.0.1-1_all.deb
 | 
						|
   frr-pythontools_6.0.1-1_all.deb
 | 
						|
 | 
						|
Note that there are no extra versions of the `frr-doc` and `frr-pythontools`
 | 
						|
packages (because they are for architecture ``all``, not ``amd64``), and the
 | 
						|
version for Debian 10 does **not** have a ``~deb10u1`` suffix.
 | 
						|
 | 
						|
.. warning::
 | 
						|
 | 
						|
   Do not use the ``-`` character in the version suffix.  The last ``-`` in
 | 
						|
   the version number is the separator between upstream version and Debian
 | 
						|
   version.  ``6.0.1-1~foobar-2`` means upstream version ``6.0.1-1~foobar``,
 | 
						|
   Debian version ``2``.  This is not what you want.
 | 
						|
 | 
						|
   The only allowed characters in the Debian version are ``0-9 A-Z a-z + . ~``
 | 
						|
 | 
						|
.. note::
 | 
						|
 | 
						|
   The separating character for the suffix **must** be the tilde (``~``)
 | 
						|
   because the tilde is ordered in version-comparison before the empty
 | 
						|
   string.  That means the order of the above packages is the following:
 | 
						|
 | 
						|
   ``6.0.1-1`` newer than ``6.0.1-1~deb9u1`` newer than ``6.0.1-1~deb8u1``
 | 
						|
 | 
						|
   If you use another character (e.g. ``+``), the untagged version will be
 | 
						|
   regarded as the "oldest"!
