现在Windows系统的主流编译环境有Visual Studio，Broland C++ Builder，Dev-C++等，它们都是支持OpenGL的。但老师上课选择VC++ 6.0作为学习OpenGL的环境。
但是我自己选的是VS2010 比较好用。
2.安装glew-1.9.0-win32
在官方网站上面下载：
以前那个官网已经没有了，这个是新的官网
解压后.h文件放在../Microsoft Visual Studio\VC98\include\GL文件夹里，.lib文件放在lib文件夹里，.dll放在system32里面
下面就可以添加代码啦：
/*第一个OPENGL程序*/
#include <GL/glew.h>
#include <GL/wglew.h>
#include <GL/glut.h>
#include <stdio.h>
#include<windows.h> // Header File For Windows
#include<stdlib.h>
