programming with opengl extensions


I’ve got a probloem compiling that project with VC 6.0/win2K SP5/Geforce2

it complains about “texture_env_combine” being undefined (although it’s present in glh_ext.h). I’m not sure which version of openGL I’m suppose to use (1.2?), on my machine, I’ve got the basic OpenGL (1.1 I think). Never compiled code with extensions before, so if someone could help me there .

Many thanks
