Hacking on oFono
Build tools requirements
When building and testing directly from the repository it is important to
have at least automake version 1.10 or later installed. All modern
distributions should default to the latest version, but it seems that
Debian's default is still an earlier version:
# dpkg -l '*automake*'
Install new version
# apt-get install automake1.10
# update-alternatives --config automake
Working with the source code repository
The repository contains two extra scripts that accomplish the bootstrap
process. One is called "bootstrap" which is the basic scripts that uses the
autotools scripts to create the needed files for building and installing.
It makes sure to call the right programs depending on the usage of shared or
static libraries or translations etc.
The second program is called "bootstrap-configure". This program will make
sure to properly clean the repository, call the "bootstrap" script and then
call configure with proper settings for development. It will use the best
options and pass them over to configure. These options normally include
the enabling the maintainer mode and the debugging features.
So while in a normal source project the call "./configure ..." is used to
configure the project with its settings like prefix and extra options. In
case of bare repositories call "./bootstrap-configure" and it will bootstrap
the repository and calls configure with all the correct options to make
In case of preparing for a release with "make distcheck", don't use
bootstrap-configure since it could export development specific settings.
So the normal steps to checkout, build and install such a repository is
# git clone git://git.kernel.org/pub/scm/network/ofono/ofono.git
# cd ofono
Configure and build
# make install DESTDIR=$PWD/x
# find x
# rm -rf x
# make distcheck
# sudo make install
Remove autogenerated files
# make maintainer-clean
Running from within the source code repository
When using "./configure --enable-maintainer-mode" the automake scripts will
use the plugins directly from within the repository. This removes the need
to use "make install" when testing "ofonod". The "bootstrap-configure"
automatically includes this option.
Copy configuration file which specifies the required security policies
# sudo cp ./src/ofono.conf /etc/dbus-1/system.d/
Run daemon in foreground with debugging
# sudo ./src/ofonod -n -d 'plugins/*'
For production installations or distribution packaging it is important that
the "--enable-maintainer-mode" option is NOT used.
Note multiple arguments to -d can be specified, colon, comma or space
separated. The arguments are relative source code filenames for which
debugging output should be enabled; output shell-style globs are
accepted (e.g.: 'plugins/*:src/main.c').
Other debugging settings that can be toggled:
- Environment variable OFONO_AT_DEBUG (set to 1): enable AT commands
If you fixed a bug or you want to add support for something, patches are
welcome! In order to ease the inclusion of your patch, it's important to follow
some rules, otherwise it will likely be rejected by maintainers:
1) Do *not* add "Signed-off-by" lines in your commit messages. oFono does not
use them, so including them is actually an error.
2) Be sure to follow the coding style rules of oFono. They are listed in
3) Split your patch according to the top-level directories. E.g.: if you added
a feature that touches files under 'include/', 'src/' and 'drivers/'
directories, split in three separated patches, taking care not to
4) Submit patches using git send-email to firstname.lastname@example.org
