Message-ID: <5365EAD6.504@gmail.com> Date: Sun, 04 May 2014 01:23:02 -0600 From: Lance Fredrickson <lancethepants@...il.com> To: musl@...ts.openwall.com 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
