When ever I try to compile something from nehe.gamedev.net I get an error and says that it cant find the openGL api’s that he is using in the code. I cant give the exact error right now because I am not at home, but I will post it a little later. Does this mean that OpenGL is not properly installed on my machine? Im running XP pro.
You’re probably best asking this on the lwgl forum a few rows down.
Well, the tutorials at nehe.gamedev.net are gl4java, not lwjgl so this is probably the right forum.
Matt_Pociask, please post the exact error, but chances are that gl4java is not in your classpath when you compile.

I typed this in DOS
% java NeHe09
Heres the error:

Any ideas?
Well, I don’t know anything about gl4java, but I could imagine that gl4java has a jar file (something like gl4java.jar maybe? Should be in the gl4java docs anyway) that should be in the classpath when you run it.
The error definately points to a class of gl4java that it can’t find.
Try
java -cp the/path/to/gl4java.jar NeHe09
(of course replacing the path to the correct one), or you could dump the jar file in your /lib/ext directory.
Maybe some of the gl4java folks here can correct me if I’m wrong :).

Can someone tell me how to set it up? I d/l and installed the file from here:
http://www.jausoft.com/products/gl4java/gl4java_install.html
but it still doesn’t work.
