Pierre Pronchery khorben at defora.orgHi baseband developers, a couple days ago I managed to compile osmocom's binaries and firmware files from a NetBSD host, using a cross-compilation toolchain generated with the standard build script on this system. This was actually quite straightforward, but required some patches and tricks, so I figured it'd be worth posting it here. I will write the procedure in more details on my blog [1], in my case it was enough to do this: $ CPATH="/usr/include" gmake \ CROSS_TOOL_PREFIX="/home/arm/tools/bin/arm--netbsdelf-" The patch itself is certainly more interesting to discuss here. I do not expect it to be fully merged, but I think it may raise interesting points: - src/shared/libosmocore/src/Makefile.am linking with "-ldl" is hardcoded, but breaks the build on systems where it is not required; this is a usual portability issue, already solved about a thousand times, I'll try to come up with a cleaner solution here. - src/shared/libosmocore/src/gsm_utils.c I think this one is quite elegant, allowing to build even without support for backtraces; an additional #warning would help though/ - src/shared/libosmocore/src/msgfile.c here I had to bluntly emulate the functionality of the getline() call, which seems to be specific to glibc; again, it'd certainly be nicer if I added a test for HAVE_GETLINE or something along this line. - src/shared/libosmocore/src/talloc.c again, talloc seems to rely on strnlen() being part of the libc, which is already known to not be the case on MacOS X; considering it also absent of NetBSD fixes the build for me. - src/target/firmware/include/stdint.h this one is definitely more ugly, since I tricked the cross-compiler to believe /usr/include matches its specific needs I ended up with some essential type definitions already; therefore, I am not sure if this workaround would not be more harmful upstream than not. Anyway, the actual patch is attached. A few more things to NetBSD users: - my previous patch about building without GNU make is also necessary; - I haven't tested the resulting binaries on a NetBSD host; - the firmware images seem to be only partly functional at the moment.
