gl.h
glew.h
gl.h included before glew.h
如果包含了glew，就不用再包含gl.h
包含的地方
- cocos/cocos2d.h
- cocos/platform/CCGL.h

- CCGL-win32.h

最终解决办法
#include <qsize.h> // 对顺序有要求 #ifdef Q_OS_WIN #include "cocos2d.h" #include <qopenglwidget.h> #include <qopenglfunctions.h> #include <qopenglextrafunctions.h> #else // todo 验证mac #include <qopenglwidget.h> #include <qopenglfunctions.h> #include <qopenglextrafunctions.h> #include "cocos2d.h" #endif 复制代码
#include <qsize.h>是一个无关的头文件，在引入后续OpenGL相关头文件的时候，必须有引入一个头文件，否则也会报错，所以我就随便写了一个无关的头文件，具体原因为啥，我也不清楚
