Nono.

The problem is, that I DYNAMICALLY fetch the function pointer out of the 
GL library, for all GL functions.
This is done, because not all GL functions are implemented in some 
implementations !
So, there are no more dummy nope functions, and no more DLL's 
for special GL implementations !

For Windows, I use:
	wglGetProcAddress
	
	if not succesfull, I use:

		LoadLibrary
		GetProcAddress
		FreeLibrary

For Unix, I use:

	dlopen
	dlsym
	dlclose

	if on of the following exist (queried by mechanism above), I will use:

	glXGetProcAddress, or glXGetProcAddressARB, or glXGetProcAddressEXT

	otherwise, using the dlsym mechanism above !

So - how is it done for the MAC ?


Yours, Sven
