View Full Version : problems with gl.h?
ok, I am trying to run the first example (the first real code example, not pseudo-code) in the red book, and I keep getting over 100 error messages. The thing is, it says the error messages are in gl.h. I haven't editted the file in any way. Maybe someone who has it working can post their gl.h or something to see if somehow that is the problem. I can't think of anything else, and that is what the compiler error messages say. Weird, hm. Thanks, later.

You're developing on Windows, yes? Official wisdom is that you're supposed to #include <windows.h> before <GL/gl.h>, since it sets up some required #defines. However, this pollutes the living daylights out of your namespace and is generally something to avoid wherever humanly possible. In practice, I find that if I just put
#if !defined(APIENTRY) && defined(WIN32)
#define APIENTRY __stdcall
#endifbefore the #include of <GL/gl.h>, everything's tickety-boo for both MSVC (8beta1) and GCC (mingw).
Holy **** man! I completely forgot about that, lol. Thanks, it's still throwing me errors but I think I can get it from here, thanks man.

as an addition..
i already add the opengl library ...
opengl32.lib ..glu32.lib and glut32.lib in the compiler.

download and install glut library
it is availible in opengl.org
hm, now I'm getting "The procedure entry point GetPixelFormat could not be located in the dynamic link library OPENGL.dll." in a windows error box. BTW, I'm using VC++6 and the project type is win32 console application. thanks all, later.

I'm assuming you meant "opengl32.dll".
GetPixelFormat isn't an OpenGL function; it's in gdi32.lib. Are you linking to that?
nope, it says opengl.dll. and no, i wasn't linking to gdi32.lib, it didn't come with the glut pack or the opengl pack, hm. i'll look for it, thanks.
I take it back, i was linking to gdi32.lib.
