    open gl extensions

    how do i get them work?

    so there seems to be 2 ways: either use those wglSomething functions to check for specific functions and store the result ina glXARB function pointer.
    or simply use that

    sdk library there.
    so i want to go with the second option - but somehow i don't get it to work with my project - the glprocs.c file there won't compile. (errors below)

    so i have such extensions headers in my /usr/include/GL directory, but that sdk comes with its own. so should i overwrite the original headers with the ones from the sdk or better store them in another directory?

    so has anyone used that before (and got it to work)?

    glprocs.c: In function ‘void InitBlendColor(GLclampf, GLclampf, GLclampf, GLclampf)’:
    glprocs.c:57: error: invalid conversion from ‘const char*’ to ‘const GLubyte*’
    glprocs.c:57: error:   initializing argument 1 of ‘void (* glXGetProcAddressARB(const GLubyte*))()’
    glprocs.c:64: error: invalid conversion from ‘void*’ to ‘void (*)(GLclampf, GLclampf, GLclampf, GLclampf)’
    same error repeat till line >15000 *g*
    edit: im using gcc under fedora.

    ack... figured the problem out.
    the glprocs.c is a c file - and i used g++ instead of gcc to compile it... oh well... now i just get like 10k warnings :P
    (compiling with -ansi -pedantic - Wall can be a pain in the *** lol)
