连接中的错误!请大家帮忙!

刚开始学openGl,打开一个源码连接的时候出错了。
.lib,.h文件我都添了,.dll文件也有,出现了一下错误:

--------------------Configuration: PRIM - Win32 Debug--------------------
Compiling...
PRIM.C
Linking...
PRIM.OBJ : error LNK2001: unresolved external symbol ___glutInitWithExit@12
PRIM.OBJ : error LNK2001: unresolved external symbol ___glutCreateWindowWithExit@8
Debug/PRIM.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

PRIM.exe - 3 error(s), 0 warning(s)


怎么解决,谢谢!!

程序里有用到#include <GL/glut.h>,
那么需要添加什么.lib文件。
我已经添加了opengl32.lib glu32.lib glaux.lib glut32.lib,
但还是出现上面的错误!请帮忙!谢谢!

glu.dll,glu32.dll,glut.dll,glut32.dll,opengl32.dll在/system32下已经有了。
还是出错,有人遇到吗?

3个dll文件我已经在system32下添加了,重新编译很多次了,还是不行。
会不会是显卡驱动的事情?

你们试试:乱码的部分是注释,不用管他
#include <stdlib.h>
#include <GL/glut.h>
