gl

Question

kullanırken birden çok hata Ben her şeyi var rağmen C++ kullanarak bir Snake oyunu, Opengl, SDL ve GL kullanarak oluşturmaya çalışıyorum Bağlantılı doğru bir hata yığını olsun, ben etrafa baktım ve bu hataların olduğunu buldum GL kullanırken oldukça yaygın olsa da neden "GL/freeglut.h" dahil olmak üzere "windows.h" dahil olmak üzere önlemleri aldığım gibi neden alıyorum? dahil

Hatalar şunlardır:

Yanlış önişlemci makro için test ediyoruz. o _WIN32 bu

#ifdef _WIN32 
#include <windows.h> 
#endif 

nota gibi çizgi okumak olun. Diğer makro da orada tanımlandığı gibi _MINGW32_ için test etmeye gerek yok.
