gluv 编译使用
看到国外的牛们在使用这个框架，编译使用之。记录一下过程和问题：
源代码：http://www.cs.unc.edu/~walk/software/glvu/
过程和问题：
1.打开VS2008，全部转换至2008工程（初始工程是6.0版本的）
2.替换全部#include <iostream.h>为 #include <iostream>
3.将glut头文件放在#include <stdlib.h>后面，否则报错 err
4.编译成功，但是例子运行提示连接lib 有错。
5.直接改造glut.h ,呵呵，改造后头函数头部如下：
#ifndef __glut_h__
#define __glut_h__
/* Copyright (c) Mark J. Kilgard, 1994, 1995, 1996, 1998. */
/* This program is freely distributable without licensing fees and is
provided without guarantee or warrantee expressed or implied. This
program is -not- in the public domain. */
// 邵延华 添加，防止对glut.lib 的连环依赖，有错
/**//** 定义避免在glut使用atexit*/
#ifndef GLUT_DISABLE_ATEXIT_HACK
#define GLUT_DISABLE_ATEXIT_HACK
#endif
#ifdef WIN32
#include<windows.h>
#endif
#include <stdlib.h>
6.设置编译器可以连接到我们编译产生的lib。
7.编译例子
