Thread: C programming MQ error Clibmqm.so: cannot open shared object file

I have the program, which we compile to connect to MQ remotely. It was compiled OK, but when I run it, got an error message: Code: error while loading shared libraries: libmqm.so: cannot open shared object file: No such file or directory but Code: /opt/mqm/lib64> ls -ltr libmqm.so -r-xr-xr-x 1 mqm mqm 17237 Nov 22 2016 libmqm.so :/usr/lib> ls -ltr libmqm.so lrwxrwxrwx 1 root root 24 Jun 9 18:18 libmqm.so -> /opt/mqm/lib64/libmqm.so Can somebody help me to understand, why the C executable cannot find this file?

You likely need to put /opt/mqm/lib64/ in the search path for executable libs.

From Installing Code::Blocks from source on Linux - CodeBlocks

To add it to the search path for libraries do the following (as root / using sudo respectively): Add the following line to the file /etc/ld.so.conf:

...and run:

Code:

ldconfig
