Description

Module hangs forever when loading, using the example h323.conf.xml unedited from src/mod/endpoints/mod_h323, this is reproducible every time.

This is the last line seen on the console (does not appear in the logfile):
2012-04-27 20:41:15.343106 [CONSOLE] mod_h323.cpp:156 Starting loading mod_h323
After 2 hours this was still the last line shown.

I collected a gcore, the backtraces are attached. The important thread appears to be thread 23, which appears to be hanging while loading a ptlib pulseaudio plugin (does mod_h323 need to disable this plugin?).

Try using "./configure --disable-pulse" when builing ptlib, see if that helps.

While that does work, that doesn't solve the issue. This error occurs with the official Debian package, which uses these configure options:
--enable-oss --enable-v4l --disable-avc --disable-dc --enable-exceptions

Manually editing and rebuilding the ptlib package could indeed work, but using the distribution binary package would always fail to build a loadable module.
And any package updates would break FreeSWITCH.

there is no official ptlib 2.10.4 in debian stable aka Squeeze, and see compiling.txt, i don't test it with another versions.

The 'environment' details on Jira are a bit less readable than the create bug form suggests... so copy and pasted...

Debian Squeeze amd64
Installed ptlib & h323plus versions are:
ii libpt-dbg 2.10.4~dfsg-1 Portable Tools Library development debug files
ii libpt-dev 2.10.4~dfsg-1 Portable Tools Library development files
ii libpt2.10.4 2.10.4~dfsg-1 Portable Tools Library
ii libh323-1.24.0 1.24.0~dfsg-1 H.323 aka VoIP library
ii libh323-dbg 1.24.0~dfsg-1 H.323 aka VoIP library development debug files
ii libh323plus-dev 1.24.0~dfsg-1 H.323 aka VoIP library development files

These are built on squeeze from the sid sources (unchanged, just downloading from packages.debian.org and running dpkg-buildpackage) - the h323plus version 1.21.0 included in squeeze does not compile against mod_h323 (too old). http://packages.debian.org/source/sid/ptlib
http://packages.debian.org/source/sid/h323plus

(I realise this isn't a "normal" squeeze environment).

Sure, I was just adding it to be clear where the packages came from.

I'll close this ticket and reopen it if I still have problems with the recommended versions.
