Generate a top-level makefile that builds the Osmocom 2G + 3G network components.
./gen_makefile.py [configure.opts [more.opts]] [-o Makefile.output]
Configured by text files:
all.deps: whitespace-separated listing of
project_name depends_on_project_1 depends_on_project_2 ...
*.opts: whitespace-separated listing of
project_name --config-opt-1 --config-opt-2 ...
Thus it is possible to choose between e.g.
- building each of those with or without mgcp transcoding support by adding or
removing "transcoding.opts" from the command line
From the Makefile nature, the dependencies extend, no need to repeat common deps.
When this script is done, a Makefile has been generated that allows you to
build all projects at once by issuing 'make', but also to refresh only parts of
it when some bits in the middle have changed. The makefile keeps local progress
marker files like .make.libosmocore.configure; if such progress marker is
removed or becomes outdated, that step and all dependent ones are re-run.
This is helpful in daily hacking across several repositories.
Note that by default, this includes 'sudo ldconfig' calls following each
installation. You may want to permit your user to run 'sudo ldconfig' without
needing a password, e.g. by
sudo sh -c "echo '$USER ALL= NOPASSWD: /sbin/ldconfig' > /etc/sudoers.d/${USER}_ldconfig"
You can skip the 'sudo ldconfig' by issuing the --no-ldconfig option.
You can run 'ldconfig' without sudo by issuing the --ldconfig-without-sudo option.
By default, it is assumed that your user has write permission to /usr/local. If you
need sudo to install there, you may issue the --sudo-make-install option.
