如何在vc++6.0里面使用openGl？

你既可以建立Win32项目使用API，也可以建立MFC工程

（一般不用MFC框架直接用API）

我给你一个例子吧，建立Win32空项目，添加一个cpp文件，编译执行就行了

（这是一个经典的opengl框架了）代码如下：

#pragma comment(lib,"opengl32.lib")

#pragma comment(lib,"glu32.lib")

#pragma comment(lib,"glaux.lib")

#include <windows.h>

#include <gl/gl.h>

#include <gl/glu.h>

#include <gl/glaux.h>

看样子是你建的工程有问题，不然怎么会用到2.pch这种怪东西；

你新建一个控制器程序的工程试试，注意用空的工程；

然后自己建个main.cpp，把你代码拷进去编译试试；

你自己加了个GL文件夹，就要把这个文件夹放到VC6的include目录里，步骤如下：

选择菜单tools-》options-》include files目录下添加GL文件夹目录。

同样的，查看library files目录，如果dll和lib没有包含在里面，也将其所在文件夹加进去。
