There are two link-level libraries. libGL includes the OpenGL and GLX entry points and in general depends on underlying hardware and/or X server dependent code that may or may not be incorporated into this library. libGLU includes the GLU utility routines and should be hardware independent, using only the OpenGL API.

Both forms must exist so that both linking and running will operate properly. The library names are:

So the name that must be used for FFI under linux would be 'libGL.so.1'. Maybe this would make it work in general:

openGLLibraryName
	^ Smalltalk os osVersion = 'linux'
		ifTrue: ['libGL.so.1']
		ifFalse: ['GL']
