1.首先安装Glut，我选择的是下载的是FreeGlut，具体安装命令过程：

   http://freeglut.sourceforge.net/docs/install.php

   //安装过程中，出现 “ error:
X11/extensions/XInput.h: No such file or directory ”，解决：$sudo apt-get install libxi-dev

   //安装完毕后，我的电脑在/usr/local里面的/include和/lib文件夹下建立一些引用库和头文件等

2.配置Codeblocks：

  打开codeblocks，选中glut项目，选择新建，输入项目名称，会提示要求指定glut的安装路径，直接指定到/usr/ (我指定到的是/usr/local/)就可以。如果上面的两个文件都在，应该很顺利就可以建   立起项目了。 
  最后，还有一点，就是编译的时候会出现一个关于Xxf86vm的错误。右键点击项目打开项目属性窗口，看到”project settings“选项卡。点击“project's build

 options”，然后点击“Linker settings”选项卡，删除对于Xxf86vm的引用就可以正确编译了。

3.另外的简单方法：（直接使用vim即可）

   1). Install build-essential sudo apt-get install build-essential
//安装autotool，否则无法./autoconf

   2). Install opengl sudo apt-get install freeglut3-dev            //直接配置安装freeglut

   3). 编译时使用命令:：gcc
simple.c -lglut -o simple 

            其中simple.c可以使用：

/*
 * GLUT Shapes Demo
 *
 * Written by Nigel Stewart November 2003
 *
 * This program is test harness for the sphere, cone
 * and torus shapes in GLUT.
 *
 * Spinning wireframe and smooth shaded shapes are
 * displayed until the ESC or q key is pressed.  The
 * number of geometry stacks and slices can be adjusted
 * using the + and - keys.
