FreeSWITCH for Debian
---------------------

You may be reading this because you're wondering where all the files
are in debian/, such as control.  You may also be here looking for the
sound or music packages.  Read on.

Because FreeSWITCH has so many modules it was necessary to create a
system to autogenerate the majority of the packaging.  This in done
mostly in the file debian/bootstrap.sh.  This bootstrap needs to run
before any other step of the packaging, though we do try to
autogenerate it when possible.

The build dependencies, runtime dependencies, and other details about
modules can be configured in the debian/control-modules file.  Even
though this file looks a bit like a debian control file and has a
similar format, we are parsing this file ourselves so the format is a
bit more restricted.

debian/control-modules currently supports the following fields:

  # lines that begin with the hash character are comments
  #
  # every block must start with a Module field
  Module: <category>/<module_name>
  Description: <short description>
   <long description> # empty lines with "."s are not yet supported
  Build-Depends: <build deps for this module>
  Depends: <runtime deps for this module>
  Recommends: <recommended packages>
  Suggests: <suggested packages>
  Distro-Conflicts: <distributions on which this module should not be built> # not yet implemented

During bootstrap we build a file control-modules.gen.  If the
control-modules file is properly formatted, this generated file should
be identical.  This is a sanity check mechanism for our parsing, as
well as a way to automatically reorganize the file.

If the file debian/modules.conf is present, we read that file and only
build and package the files listed there.  Otherwise, we build every
module except the ones that either should not be packaged, or for
which we don't yet have good packaging.

The format of debian/modules.conf is:

  ## comments should start with two hash characters
  <category>/<module_name>

To build this package, I recommend running the following from the root
directory of your FS git working tree:

  distro=sid
  ver="$(cat build/next-release.txt | sed -e 's/-/~/g')~n$(date +%Y%m%dT%H%M%SZ)-1~${distro}+1"
  git clean -fdx && git reset --hard HEAD
  ./build/set-fs-version.sh "$ver"
  git add configure.in && git commit -m "bump to custom v$ver"
  (cd debian && ./bootstrap.sh -c $distro)
  dch -b -m -v "$ver" --force-distribution -D "unstable" "Custom build."
  dpkg-buildpackage -b -us -uc -Zxz -z9
  git reset --hard HEAD^

To build for a stable branch, do this:

  distro=sid # update as needed
  stable_ver="1.2.1" # update as needed
  # if you only want to build some modules, put them one per line here, e.g.:
  #echo "applications/mod_commands" >> debian/modules.conf
  ver="$(echo "$stable_ver" | sed -e 's/-/~/g')~n$(date +%Y%m%dT%H%M%SZ)-1~${distro}+1"
  git clean -fdx && git reset --hard refs/tags/v${stable_ver}
  ./build/set-fs-version.sh "$ver"
  git add configure.in && git commit -m "bump to custom v$ver"
  (cd debian && ./bootstrap.sh -c $distro)
  dch -b -m -v "$ver" --force-distribution -D "unstable" "Custom build."
  dpkg-buildpackage -b -us -uc -Zxz -z9
  git reset --hard origin/master

Alternatively, you can build using our automated tools.  To build the
source packages and all supported binary packages for sid, wheezy,
squeeze on i386 and amd64, run the following as root from a clean
Debian sid 'buildd' image:

  aptitude update && aptitude upgrade
  aptitude install -y \
    rsync git less cowbuilder ccache \
    devscripts equivs build-essential
  mkdir /usr/src/freeswitch
  git clone git://git.freeswitch.org/freeswitch /usr/src/freeswitch/src
  cd /usr/src/freeswitch/src
  # if you only want to build some modules, create a modules.conf
  # outside the source tree and add -f ../path/to/modules.conf to the
  # command below.  See ./debian/util.sh -h for further usage
  # information.
  ./debian/util.sh build-all -bn -z9

The source packages for sounds and music on hold are maintained in a
separate repository.  Each set of sounds has a separate version number
and the processing of the sounds is quite different from what we're
doing here, so trying to maintain a merged debian/ between FreeSWITCH
and the sounds and music would be a mess.

To build the Debian packages for freeswitch-sounds-* and
freeswitch-music-*:

  git clone https://github.com/traviscross/freeswitch-sounds.git
  cd freeswitch-sounds && cat debian/README.source
