Linking problems

["M.C. Vernon" <mcv21@cus.cam.ac.uk>]

Hi all,

	More compiliation problems I'm afraid: I'm trying to get this
simple program to compile. It produces an object file OK, but ld
complains: 
cannot open -lMesaGL: no such file or directory.

This is confusing, given I have mesage-dev installed, and libMesaGL.a is
next to libMesaGLU.a in the directory, which ld seems to find fine.

Mystified is,

Matthew
