great! I'll give it a try.
BTW: Is there a binding for cgGL? Before you told me this, I've already moved on by wrapping my OpenGL calls in C functions and call them in Common Lisp via CFFI. It worked for both SBCL and CCL until I added cg support. After that CCL compaint "invalid profile type" and the image is exactly the one without the cg shader. So it would be very helpful if there is a well-written cg binding for cl-opengl.

Sounds like https://github.com/3b/cl-opengl/issues/42 which is fixed in the git repo at https://github.com/3b/cl-opengl and should be in next quicklisp update.

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. Thanks!!!

Hi!
I'm new to cl-opengl and was reading this tutorial:
http://nklein.com/2010/06/nehe-tutorial-02-drawing-triangles-and-quadrilater...
I've downloaded tut02.lisp, but have trouble running it.
On my machine, ccl 1.6 (windows XP, 32 bit, OpenGL 1.5) gives:
; Warning: Don't know how to setup a hook before saving cores on this Lisp. ; While executing: #<Anonymous Function #xCE06D0E>, in process listener(1).
Error: Couldn't find function glClearColor While executing: CL-OPENGL-BINDINGS::GENERATE-GL-FUNCTION, in process listener
(1).
Type :GO to continue, :POP to abort, :R for a list of available restarts. If continued: Skip loading "tut02.lisp" Type :? for other options.
But SBCL 1.1.4 (win32-thread fork) runs perfectly.
On another machine (windows 7, 64 bit, OpenGL 4.3), both ccl 1.6 and
SBCL
(both 32-bit) gave the error message before.
Could anyone give me some suggestions? Thanks in advance
