Hi there - 

I'm in a similar boat to Gilbert, and was wondering what the current
state is with cl-opengl under win32.  Does it currently work for
anyone on win32?

My opengl32.dll doesn't have, for example, an entry point for
glActiveTexture.  Searching on the net suggests that the way to get
hold of this function under windows is to do something like (in C):

glActiveTexture = (PFNGLCLIENTACTIVETEXTUREARBPROC)
        wglGetProcAddress("glActiveTextureARB");

I've had a look through the archives but couldn't find anything
relevant.  I found the messages about getting hold of freeglut.dll
(which suggests to me that people are successfully running cl-opengl
under windows), but didn't see anything else about getting hold of the
extensions.


Is there something I need to install, or should I start trying to get
these functions through wglGetProcAddress?
