Subject: Minimal asterisk compilation
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
