Ok guys, i dunno if i am an idiot or what, but i have written an extension loader for opengl, right, but this is the problem, if i put the declarations for the functions in the header, anything else that links to it gets an error, and that sucks, it is the 2005 link error , already defined in object, i dunno what i am doing wrong, i am structuring everything like i always do, i would use teh functions provided by NVidia in the SDK, but it wont work either, argh, so if i put the function pointer declarations in a different file( the one with the fuction call to load them, ) then the other files can''t "see" the functions... suck
