I found the problem. It was with the shared library path. After setting the system environmental variable LD_LIBRARY_PATH appropriately it worked fine.

$ export LD_LIBRARY_PATH=<my custom lib path>:$LD_LIBRARY_PATH

$ ./sbin/kamailio -E -d -f /home/ajay/projects/video_conf/etc/kamailio/kamailio.cfg

Subject: [SR-Users] Error while loading modules, if given a custom library path

Hi

I have trouble loading modules from a custom lib directory. It works fine if the libraries are located under PREFIX/lib/Kamailio/ (PREFIX is the path that I gave while building Kamailio). But on the target I will have to keep the libraries in a custom directory.

I tried by changing the mpath in kamailio.cfg. Also I tried by giving the path in –L option while invoking kamailio. It is not working. It fails with the following errors, even if the libraries are present at the location where it compains.

I searched but couldn’t find any answer why it is failing, though it is supposed to work. Please help me.

$ ./sbin/kamailio -E -d -f /home/ajay/projects/video_conf/etc/kamailio/kamailio.cfg -c
