Regarding Chris' post - I ran into a lot of problems too since there are old versions of HOpenGL and corresponding examples floating around out there with differing advice, such as at http://www.haskell.org/HOpenGL/. I'm not sure why it hasn't been updated since it's off of the main haskell.org. There are some sites that include a lot of Red Book examples that should just compile and work with the method I gave (such as ghc --make Planet.hs). Anyone know a reason why some tutorials use the -package GLUT option? Try some of these links: This should have the newer examples (can anyone tell me if there are any better sites than this?) http://cvs.haskell.org/cgi-bin/cvsweb.cgi/~checkout~/fptools/libraries/GLUT/... This is a newer tutorial (blog): http://blog.mikael.johanssons.org/archive/2006/09/opengl-programming-in-hask... This is older: http://www.haskell.org/~pairwise/HOpenGL/HOpenGL.html -Jamin ____________________________________________________________________________________ 8:00? 8:25? 8:40?
