Default Re: Interesting problem, and would like explanation

For anything above OpenGL 1.1, you need to define GL_GLEXT_PROTOTYPES if you want glext.h to define function prototypes as well as typedefs. Otherwise, you need to use the typedefs and glXGetProcAddress and decide at runtime whether that feature is supported for a given GL implementation.
