How to prevent macro redefinition

Question

After working some time on my project, this warning begins to appear:

2>Game.cpp
2>c:\\program files\\microsoft sdks\\windows\\v6.0a\\include\\windef.h         


        

Answer 1

The problem is in the file Game.cpp. Try to include windows.h before glfw.h. There is a guard in glfw.h which will prevent that warning:

#ifndef APIENTRY
 #ifdef _WIN32
  #define APIENTRY __stdcall
 #else
  #define APIENTRY
 #endif
 #define GL_APIENTRY_DEFINED
#endif // APIENTRY
