This is not an answer but a plea for help. I am brand new to Linux and cannot figure out how to implement the solution that people say have worked for them. If anybody wouldn't mind explaining:

• how to add a conf file to /etc/ld.so.conf.d/

• what the conf file should contain

• what the conf file should be named

• how to run the ldconfig command (in the command line? what exactly should the command say?)

I would be tremendously grateful thank you!
