Hi again,<br><br>I've been working with a number of OpenGL 2.0 concepts such as shader programs, and I've come across a bit of a snag with ATI's OpenGL 2.0 support. <br><br>The shader programs work fine with the
libGL.so as supplied by nvidia (on my home machine), but when using libGL.so from ATI on my work machine, functions such as create-shader fail, as there is no such symbol in the library. Using glXGetProcAddress to get the function pointer for glCreateShader, however, is the required work around for the ATI library.
<br><br>I was tempted to create a cl-glew library binding, however this won't really work that well, as _that_ library also doesn't include all the symbols, and relies on C preprocessor macros heavily to do the right thing.
<br><br>Anyways, I was thinking instead of modifying cl-opengl instead to (perhaps dependant on some switch?) use glXGetProcAddress for those functions that aren't directly callable, memoized of course.<br><br>Does this sort of thing make sense in this context? It's been a while since I've done a lot of lisp, and I'm also not super familiar with FFIs, so I want to make sure I do this the lispyiest way possible.
