What exactly is the problem?
You need to pass paths to the library folders to compiler.
Checkout section Using Library/Install and Compile in Imaging's documentation for FPC compiler setup.

Can someone guide me in installing the Library for Free Pascal. I hardly manage by my self. I tried and didn't succed. Can't really find any useful information. Useful means that it helps me getting further because i'm blocked.

Waiting response,
