GLvoid?
Author
I just started reading through the NeHe tutorial, and of course when I finished the code, I got a ton of build errors. I figured the most important ones to solve first are the ones that say GLsizei and GLvoid are undeclared identifiers. Can someone tell me where those are defined? I have gl.h, glu.h, and glaux.h included. I just need to figure out which one is acting screwy.
*EDIT*
Nevermind, I just found it in gl.h, but now I wonder what the purpose is of even using GLvoid and GLsizei, since GLvoid is just void and GLsizei is just an int. What's the point?
GLvoid is likely for consistency...everything else gets a typedef, why not void? GLsizei looks as though it is meant to be the equivalent of size_t. Mostly just a way of providing extra type information, even if c++ doesn't respect it. GLsizei somefunc() isn't just returning any old integer, it is returning a size of something.

For some reason, Visual Studio is very unhappy about my use of GLvoid and GLsizei.
The last line there where GLsizei and GLvoid are mentioned is where it freaks. I can't figure it out.

Well, I stuck my own typedef into the code for GLvoid and it worked just fine, so apparently it isn't really including gl.h for some interesting reason.

Your problem is that the preprocessor removes everything before #include "stdafx.h". #include "stdafx.h" must be before everything (except for comments).
