Re: [ooc-compiler] Undefined reference from interface module

[Stewart G. <sgr...@ii...>]

Hi August,

If you're working with OpenGL, you might like to check out my 
"quick-and-dirty" translation here:
   http://maple.murdoch.edu.au/~stewart/files/interfaces/gl/

The module GL.Mod is derived from "gl.h" and "glu.h" under Windows NT. 
It needs a some cleaning up, but should be usable. For example, there 
are numerous "AutoPtr_" declarations which are generated to remove type 
constructors in procedure declarations. These should be given names 
that are meaningful in context. I did this a while back, but never 
tested it (other than verifying that it compiles) since I eventually 
managed to do what I wanted using GDI functions. I suspect that if you 
add your "LINK LIB" declarations to the module header it will probably 
work. Either way, I'd be interested to know if you have any success 
with it.

Cheers,
   Stewart
