我的程序使用Qt和OpenGL。它在Linux和Mac下正确编译。 在windows上编译时，我需要#include windows.h才能使用OpenGL，代码如下，

#if defined(_WIN32) || defined(_WIN64) || defined(WIN32) || defined(WIN64)
#include <windows.h>
#endif
#ifdef __APPLE__
#include <OpenGL/glu.h>
#include <GLUT/glut.h>
#else
#include <GL/glu.h>
#include <GL/glut.h>
#endif

但是，有很多错误消息，如

如果我不#include windows.h，则不会出现这些错误。 我使用VS2013和Qt 5.3。

Microsoft Windows上的OpenGL与WGL绑定，后者又与GDI绑定。

因此，如果没有首先包含一些定义GDI / Windows预处理器令牌的特定于Windows的标头，例如{{1}，则不能#include <gl/gl.h>（您通过包含<GL/glu.h>来间接执行此操作） }和WINGDIAPI。但实际上，Windows上的任何OpenGL程序都与特定于Windows的任何内容（标题）相关联。

APIENTRY定义WinDef.h，APIENTRY定义WinGDI.h - 包括WINGDIAPI带来这两个标题（不幸的是还有很多其他垃圾）。所以包括Windows.h主要是方便;要 最低限度 在Windows上编译OpenGL软件，您应该Windows.h后跟#include <WinDef.h>，然后最后#include <WinGDI.h>。

或者，您可以在#include <GL/gl.h>之前#define WIN32_LEAN_AND_MEAN， 显着 减少包含的不相关内容的数量那个标题。许多Visual C ++项目实际上在首次创建时默认定义了预处理器定义，您可能希望查看项目是否以这种方式配置。

windows.h使全局命名空间变得混乱，有大量的错误，如ERROR，Rectangle ...

解决问题的一种方法是声明自己所需的功能（我想这不是太多的工作，因为你不需要超过10个功能）。您可以调用包含文件wgl.h或其他内容。

__declspec(dllimport) void* __stdcall wglCreateContext(void* hdc);
//... Other functions you need

OpenGL API在windows.h之外定义，所以没问题
