Hi! I'm new to cl-opengl and was reading this tutorial:
http://nklein.com/2010/06/nehe-tutorial-02-drawing-triangles-and-quadrilaterals/ 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 - Rujia
