Hi Vasu,

This is a dynamic linker problem. Linking with shared libraries is done every time you run a program. The compiler has indeed found the libraries and that is why your `a.out' has been created.

The dynamic linker looks into the `LD_LIBRARY_PATH' shell variable to find the libraries. So you have to put `/myinst/lib/' in this variable.

You can do this with a command like below. You can also put it in your `~/.bashrc' to be available at startup of your interactive bash sessions.

export LD_LIBRARY_PATH="/myinst/lib/:$LD_LIBRARY_PATH"

For more on custom installation paths, you can see the explanations in the link below.
