Hello, Using matlab 2013a in Ubuntu 12.04 I wrote a small function in matlab, compiled it as a c++ shared library and wrote a c++ app to access the data from the library. It compiled ok. The problem is the app only works if I run as sudo. If I run as non sudo, I'm not able to initialize the compiled library, it returns false.
Any ideas? Its really important that I don't run as sudo.
Thank you, -Nav

Did you change the ownership of the file and its access permissions?
( unix commands chmod chown)

Yes, I made sure user had read write access to the shared lib and chowned it so user is the owner. In both cases, sudo and non sudo , mclinitialzation seems to return true but libinitialzation returns false in non sudo case.
