A "make world" build system for OpenBSC and related executables in an easy and automated way. One of the goals was to build all binaries statically with no external Osmocom dependancies.

The system does not pull dependencies for you - you will ahve to install them yourselves.

The only change outside of the build directory is installation of libraries and binaries with make install. You also have an option to select arbitrary PREFIX and install everything to a selected directory instead of /usr/local/ to eleminate system changes completely.

Right now subprojects point to specific commits of all projects to make sure everything builds and runs properly. If you need another version - just update the git submodules.

Checkout this repo with all submodules.

git clone https://github.com/fairwaves/osmo-combo.git
cd osmo-combo
git submodule init
git submodule update

Open Makefile and edit PREFIX variable to your taste.

You may also want to edit all target to exclude/include certain projects from the build.

If you want a static build, run the following command to apply a relevant patchset:

./apply_patches.sh static-build

This will build and install all the packages.

make

Make generates status/timestamp files in the build directory which have <project>.<status> format, e.g.:

libosmocore.configured
libosmocore.installed
libosmocore.made
openbsc.configured
openbsc.installed
openbsc.made
... etc

These files are then used by make to check which steps has been successfully finished. So if you want to re-run a certain step, you should remove the corresponding file. E.g. if you want to re-build openbsc without re-configuring it, just remove the openbsc.made file.

Patches are stored in the patches/xxx subdirectories. Right now we provide patches to enable static build, which are stored in the patches/static-build directory. Patches are stored in a "file per project" format.

To apply a patchset:

./apply_patches.sh <dir>

To generate/update a patchset:

./apply_patches.sh <dir>
