Musl has caught my eye, and I've compiled various one-off binaries, but
wanted to compile a minimal asterisk setup for an embedded mipsel device
(router).
I've put my code here.
https://github.com/lancethepants/asterisk-embedded-musl
Sorry, I do things hacky.
I later moved over libc.so, and created ld-musl-mipsel.so.1
All the binaries I've compiled so far work fine, but the modules in
asterisk have issues.
One example is
# /opt/asterisk/bin/ldd ./codec_ulaw.so /opt/asterisk/bin/ldd (0x55550000)
libc.so => /opt/asterisk/bin/ldd (0x55550000)
Error relocating ./codec_ulaw.so: ast_format_set: symbol not found
Error relocating ./codec_ulaw.so: __ast_mulaw: symbol not found
Error relocating ./codec_ulaw.so: ast_unregister_file_version: symbol
not found
Error relocating ./codec_ulaw.so: ast_module_unregister: symbol not found
Error relocating ./codec_ulaw.so: __ast_lin2mu: symbol not found
Error relocating ./codec_ulaw.so: ast_unregister_translator: symbol not
found
Error relocating ./codec_ulaw.so: __ast_register_translator: symbol not
found
Error relocating ./codec_ulaw.so: ast_register_file_version: symbol not
found
Error relocating ./codec_ulaw.so: ast_module_register: symbol not found
This happens for each module. The symbols look to be inside when looking
at them with the readelf command. This breaks the all of asterisk.
I tried throwing in -fPIC in the LDFLAGS but did nothing.
In order to get it compile at all, I grabbed some patches from here.
https://github.com/uggedal/aports/blob/master/main/asterisk/musl-glob-compat.patch
and also did some cheating throwing in a cdefs file from the same repo
mentioned, and some sed commands to fix some PTHREAD stuff.
I thought I was home free once it compiled, but I can't figure out why
the modules won't work. Maybe there's something simple I'm
overlooking. Any suggestions are appreciated.
cheers,
Lance

Those are symbols from the main 'asterisk' binary that the modules use.
ldd cannot resolve them because it does not know about the main
asterisk binary anything.
The modules should work just fine in case asterisk loads them.

Just try running them. I think ldd will give similar errors even with
glibc.

If that's the case, the problem is most likely that -rdynamic is
missing from the LDFLAGS. No idea why the build system would have
omitted it...
