Yeah SGI !

My recent quest for OpenGL 2.0 function support in my dev environment has hit a milestone. I was able to hack out the pieces of the ATI SDK I needed (rbtree.h, string.cpp, string.h, Platform.cpp, Platform.h, GLextensions.cpp, GLextensions.h) and get them compiling in place of my old ATIextensions.[ch] files. I started out with MAX_GL_1_3 and everything seems to be working since I am currently using only ARB extensions which are turned on for all MAX_GL_X_Y settings. I bumped it up to MAX_GL_1_5 and everything still worked so I tried MAX_GL_2_0 but then it exploded! I got more than 1500 errors due to the fact that the glati.h that is included in the SDK does not contain API binding for the OpenGL 2.0 functions. Now we have a problem in need of a solution, google time.

I searched for the missing API entry string and found a reference on the SGI site for it in their glext.h file. Which has every extension and OpenGL function available (or so it seems). I deleted glati.h and replaced the includes with glext.h and now everything is compiling at MAX_GL_2_0. I have yet to try out the functions but it looks promising.

I’ll post again after testing the functionality.
