[Freeswitch-users] Linking problems with mod_portaudio.so module

[Jason White]

I can report that this problem (the failure of mod_portaudio.so to be linked
properly) still persists as of revision 13970.

The operating system is Debian Testing, and the difficulty began after
upgrading from Libtool 1 to Libtool 2.2.6a.

If anyone else can reproduce this or suggest a means of tracking down the
cause, this would be much appreciated.

The result of running ldd -r on mod_portaudio.so is as follows. It shows that
most of the undefined symbols are from the Alsa library.

I have also searched my build logs, (even with VERBOSE=1) but without locating
any output that seems suspect.
