Visual Studio OpenGL 配置方法

Visual Studio OpenGL 配置方法

OpenGL开发库的文件包含：

动态链接库文件（.dll）

glut32.dll、glu.dll、glut.dll、OPENGL.DLL。

头文件（.h）

GL.H、GLAUX.H、GLEXT.H、GLU.H、GLUT.H、WGLEXT.H。

库文件（.lib）

GLAUX.LIB、Glu32.lib、Glu.lib、glut32.lib、glut.lib、Opengl32.lib、opengl.lib。

配置方法：

1.将开发库中的.h文件拷贝到Visual C++ 6.0的\Include\GL目录中

2.将.lib文件拷贝到Visual C++ 6.0的\lib目录中

3.将.dll文件拷贝到操作系统的system32目录中

注意：

忘记

#pragmacomment(lib, "XXX.lib")

会造成链接错误！
