[Freeswitch-users] ftmod_libpri won't load (undefined symbol: ftmod_pritap_module_interface**)

[George Diamantopoulos]

It seems I found the culprit (the hint was that no other ftmod module would
load, so it wasn't libpri/freetdm build related)... After configuring
wanpipe, running wancfg_ftdm, editing freetdm config files (xml and
otherwise), ftmod_pritap was loaded sucessfully.

It would be nice if the error message were a bit more helpful, though.
undefined symbol does ring the "something-went-wrong-with-linking" bell...
