大家好。是这样的，写了一个opengl程序，编译通过，运行的时候弹出无法定位程序输入点_glutInitWithExit 于动态链接库glut32.dll上。请问啥问题啊?

估计是glut库版本或者编译设置的问题 你把源代码 以及你的glut库上传大家分析一下

麻烦你们了！

我按你们说的换了glut32.lib   结果运行是出现                                                   unresolved external symbol ___glutInitWithExit@12                                           unresolved external symbol ___glutCreateWindowWithExit@8  的错误。

行了。激动！激动啊！

果真是版本问题，换了几个版本才行！老天啊，这东东对于我们这种初学者真是要命！

问题中学到的东西才能记住
