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

[Ajay Sabat]

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
