Hi Guys I'm having trouble getting mod_fax to load. Running on Debian testing (squeeze). Everything is installed as per - http://wiki.freeswitch.org/wiki/Installation_Guide. (dpkg-buildpackage etc) When trying to load the fax module I get: 2010-02-19 01:48:17.554935 [CRIT] switch_loadable_module.c:882 Error Loading module /opt/freeswitch/mod/mod_fax.so **/opt/freeswitch/mod/mod_fax.so: undefined symbol: TIFFDefaultStripSize** And when a fax is sent, I'm getting: 2010-02-19 01:04:57.355330 [ERR] switch_core_session.c:1490 Invalid Application rxfax I guess because mod_fax isn't loaded. I've got libtiff4 and libtiff4-dev installed: ii libtiff4 3.9.2-2 Tag Image File Format (TIFF) library ii libtiff4-dev 3.9.2-2 Tag Image File Format library (TIFF), development files ii libtiffxx0c2 3.9.2-2 Tag Image File Format (TIFF) library -- C++ interface Just tried updating to the latest svn trunk (16700M) and it hasn't made any difference. From googling, it suggests that it could be because the module is complied against a different one currently running on the system, however I'm not sure how this can be the case, there is only the one version installed. Any suggestions as to what I can try? Any help appreciated Russ
