hi all OS ubuntu 12.04 or ubuntu 10.04 - just did a check with debian 7 - same problem Module carrierroute not working starting from version kamailio 4.0.x trying to activate carrierroute in kamailio.cfg loadmodule "carrierroute.so" i get the following error when starting kamailio 0(7547) ERROR: <core> [sr_module.c:572]: load_module(): ERROR: load_module: could not open module </usr/lib64/kamailio/modules/carrierroute.so>: /usr/lib64/kamailio/modules/carrierroute.so: undefined symbol: cfg_set_error_function 0(7547) : <core> [cfg.y:3567]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 219, column 12-28: failed to load module ERROR: bad config file (1 errors) the function "cfg_set_error_function" is different, if i use another linux system. I tested with ubuntu 12.04 & 10.04. I installed with apt-get install and I also compiled the version using GIT. I did a crosscheck with kamailio 3.3 and there it seems to work! Any idea?
