Comment 2 for bug 891054

For some reasons not yet fully understood, dynamic plugins loaded by liquidsoap do not properly declare their dependencies to the dynamic loaded, which results in errors such as:

2011/12/04 20:47:30 [dynamic.loader:2] Could not load plugin file /usr/lib/liquidsoap/1.0.0-beta3/plugins/lame.cmxs: error loading shared library: /usr/lib/liquidsoap/1.0.0-beta3/plugins/lame.cmxs: undefined symbol: id3tag_set_title.

Indeed:

dnch@ubuntu:~$ ldd /usr/lib/liquidsoap/1.0.0-beta3/plugins/lame.cmxs
        linux-vdso.so.1 => (0x00007fff925ff000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f3a76530000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f3a76ae1000)

libmp3lame is missing from that list.

I have no other solution for now than to rebuild the package:

as root:
# apt-get build-dep liquidsoap
(you may need to enable some sources for packages' sources in
/etc/apt/sources.list)

Then as a user:
~ apt-get source liquidsoap
~ cd liquidsoap-<VERSION>
~ dpkg-buildpackage
