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.

Did you make bootstrap.sh and configure before compilation?

We have no issues on Ubuntu 9.04 (libtool 2.2.6a).

Sorry - I misread the question.

The error is:

freeswitch@default> load mod_portaudio
-ERR [module load file routine returned an error]

2009-06-27 12:30:00.740316 [CRIT] switch_loadable_module.c:871 Error Loading
mod
ule /opt/freeswitch/mod/mod_portaudio.so
**/opt/freeswitch/mod/mod_portaudio.so: undefined symbol: snd_config**
freeswitch@default>

There is no error during the building.

As a further note on this subject, temporarily downgrading to libtool 1.5.26
and rebuilding FreeSWITCH gave me a working mod_portaudio.so module.

Obviously this doesn't solve the problem, but it does prove that, as
suspected, the migration to libtool 2.2.6a was the cause.

Any suggestions on how to track down the build system bug would be welcome.
