[SR-Users] Issue building sip-router (kamailio flavour)

Hi, When I build sip-router (from master) with kamailio flavour using: make config mode=debug FLAVOUR=kamailio; make all; make install I'm getting this error when trying to start kamailio: ERROR: <core> [sr_module.c:396]: ERROR: load_module: could not open module </usr/local/lib/kamailio/modules_k/tmx.so>: /usr/local/lib/kamailio/modules_k/tmx.so: undefined symbol: _tm_table On the other hand, if I use: make FLAVOUR=kamailio cfg; make all; make install kamailio starts correctly. I've tried also: make mode=debug FLAVOUR=kamailio cfg with no luck either. What's the problem? How should I compile kamailio with debugging so it starts correctly? Thank you in advance. Regards, Santi
