Tom Thanks for the reply. My GSL libraries, 'libgsl' and 'libgslcblas', are in the /usr/lib directory as GSL and the GSL development files were installed via Fedora 8 RPM's. I'm a relative newbie to programming, so I thought the -L switch is only required to add a non-standard library location to the directories searched for libraries. I will give it a go.
