I typed up NeHe''s tutorial 1, and when i compile I get this error implicit declaration of function `int CreateGLWindow(...)'' i included but it still doesnt work.

Is CreateGLWindow in another file? If so, you need to have some type of extern declaration. Is CreateGLWindow below the function calling it in the source files? If so, you need to put a prototype for it above the current function.

this is the code for that part:


if (!CreateGLWindow("NeHe''s OpenGL Framework",640,480,16,fullscreen))
{
return 0; }

how could i do a prototype for that?

Are you sure you should be doing OpenGL if you don''t know enough C/C++ to do that on your own? I''ll help you anyway though:

/*A generic prototype*/returnvalue Name(type, type, type);/*One for CreateGLWindow. Put this near the top of the source file.*/BOOL CreateGLWindow(char *, int, int, int, bool);

heh, i''m pretty sure i know My C++, heh, anyways, thanks

but now i get this linker error message

d:\programming\projects\opengl\template.o(.text+0xb46):template.cpp: undefined reference to `CreateGLWindow(char *, int, int, int, bool)''

I also have these .libs attached:

-lopengl32 -lglu32 -lglut32 -lgdi32 -luser32 -lglaux

I tryed #define CreateGLWindow, but didnt work.

You''re not linking a required file. Is CreateGLWindow in your file? It''s NOT a standard function. If it''s in another file you need to link it also. If you don''t have the file it''s in, you need to write your own or not use it. Those are the easiest situations I can think of, did you simply download one of NeHe''s tutorials?

I''m pretty sure you don''t.

umm....i got it to compile, thx, but now ive run into another problem, when i run the program, if i select windowed mode, you can see a program down in the task bar, but you cant see the program on your desktop, if i run the mouse over the part of the screen where the window is supposed to be (top left) my mouse icon shows its loading, So its there, but its not, same with fullscreen. Do you know what my problem might be?
