I've tested on 3 other machines. 2 with OpenGL 2.1 and 2 with OpenGL 4.3 It seems that OpenGL 2.1 machines can run SBCL executable while OpenGL 4.3 cannot. But on all machines ccl executable cannot run.
I don't think glClearColor has changed between OpenGL 2.1 and OpenGL 4.3, from the latest reference: http://www.opengl.org/sdk/docs/man/xhtml/glClearColor.xml So I'm confused. Any help would be appreciated.
