本文档详细介绍了在Visual Studio环境中配置OpenGL遇到的问题及解决方案，包括如何解决未解析的外部符号错误，以及如何处理因缺少glut32.dll而导致的程序启动失败问题。

1.opencv和OpenGL的配置

参考牧野的博客OpenGL+VS2012编译环境配置：http://blog.youkuaiyun.com/dcrmg/article/details/53049070

2.OpengGL 在配置时出现impglutInitWithExit@12 或imp____glutCreateWindowWit

unresolved external symbol __imp____glutInitWithExit@12 unresolved external symbol__imp____glutCreateWindowWithExit@8
I have the folling files in the following locations: -
glut.h
glu.h
gl.h
C:\Program Files\Microsoft Visual Studio 8\VC\include\GL

glut.32.lib
C:\Program Files\Microsoft Visual Studio 8\VC\lib

glut32.dll
glu32.gll
C:\WINDOWS\system32

I make a new project (Win32 Console App).
Set the Additional Dependencies under
Project | Properties | Config Properties | Linker | Input
I have: -
opengl32.lib glu32.lib glut32.lib

This is basically what just about every site I look at tells me to do.
So I copy over some code that I know compiles and runs under my Dev C++ setup...
And it fails to compile with the following errors: -
1>main.obj : error LNK2019: unresolved external symbol __imp____glutInitWithExit@12 referenced in function _glutInit_ATEXIT_HACK@8

1>main.obj : error LNK2019: unresolved external symbol __imp____glutCreateWindowWithExit@8 referenced in function _glutCreateWindow_ATEXIT_HACK@4

This is didn't happen a little while ago, as I was trying to solve a previous problem. This was that when I tried to run a successfully compiled program, an error would say: -
The procedure entry point __glutInitWithExit could not be located in the dynamic link library glut32.dll

solution:
Try define the following line right before including the header, glut.h.

#define GLUT_DISABLE_ATEXIT_HACK

3.运行出现问题：无法启动此程序因为计算机丢失glut32.dll

将下载的压缩包解开，将得到5个文件（glut.dll, glut32.dll, glut.lib, glut32.lib,glut.h）

（1）把glut.h复制到x:\Program Files\Microsoft\Visual Studio 10.0\VC\include\gl文件夹中,如果没有gl这个文件夹则可以自己新建一个。（x是你安装VS的盘符号）

（2）把解压得到的glut.lib和glut32.lib放到静态函数库所在文件夹（即与include并排的lib文件夹下）。

（3）把解压得到的glut.dll和glut32.dll放到操作系统目录下面的system32文件夹内。（典型的位置为：C:\Windows\System32）

（注：如在开发应用程序时用到OpenGL辅助库函数，则还需下载相应动态链接库，包含glaux.dll, glaux.lib, glaux.h，相应步骤同上）

解决方法：如果是windows7 32位系统，那么上述环境配置已经完成。如果是64位系统话按照上述设置，当编译一个程序是会图示错误“无法启动此程序,因为计算机中丢失glut32.dll。。。”。问题出在第（3）步，这时应该将glut.dll和glut32.dll放到操作系统目录下面的C:\Windows\SysWOW64文件夹内，这时再编译就没有问题了。
