| Generate a top-level makefile that builds the Osmocom 2G + 3G network components. |
| |
| ./gen_makefile.py projects.deps [configure.opts [more.opts]] [-o Makefile.output] |
| |
| Configured by text files: |
| |
| *.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. |
| - 2G+3G or 2G-only by picking a different projects_and_deps.conf, |
| - and between building each of those with or without mgcp transcoding support |
| by picking a different configure_opts.conf. |
| |
| 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| removed or becomes outdated, that step and all dependent ones are re-run.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. |
