It does not work like that. GLSL binary stuff is provided by the drivers
of your graphic video card.
The only thing that you may need beyond your compiler is:
- A good tutorial on how to set up and using glsl shaders
- glext.h (google for it) which is a handy file #define'ing preprocessors
macro that you can further use to declare your own function pointers to
GLSL ARB functions.
Windows XP client OpenGL API version is 1.1, which does not know anything
about shaders, that why you have to use the OpenGL extension mechanism to
get pointers of function related to GLSL, those being located in the
driver.
So what you will have to do once the opengl context created is to load
function pointers via wglXGetProcAddress (or something named like that),
then use those function pointers.
