I''ve this problem. Whenever I include the glut.h library, I get error in this line (of the glut.h): extern _CRTIMP void __cdecl exit(int); //line 146 I''ve downloaded many times the library, and I''ve installed the .dll and .lib correctly. But always have the same error. For example, using the tutorials of Nehe''s page about Glut. So, what I''m doing wrong?

Uhh sorry, I forgot

This is the message:

[C++ Error] glut.h(146): E2337 Only one of a set of overloaded functions can be "C"

I''m new with C++ so I don''t get it all.

Are you including the file twice?

Do you have a function named exit in your program?

Have you included or ?

glut.h is correct.

You're using Visual C++ 7.0, which changed the prototypes for exit and abort (addedd a __declspec(noreturn) - a Microsoft extension, not standard C++.

Go read the 'correct' declaration in and mirror it into glut.h with an #ifdef testing that you have the 'right' version of Visual C++.

Edit: Ah, well, here's the code to be substituted in glut.h


#if defined(_WIN32)
# ifndef GLUT_BUILDING_LIB
#  if _MSC_VER >= 1200
	_CRTIMP __declspec(noreturn) void   __cdecl abort(void);
	_CRTIMP __declspec(noreturn) void   __cdecl exit(int);
#  else
	_CRTIMP void   __cdecl abort(void);
	_CRTIMP void   __cdecl exit(int);
#  endif
# endif
#else
/* non-Win32 case. */
