CentOS6.2 install OpenGL development library under https://blog.51cto.com/wzsts/1828007
do develop Qt under Linux, run the program when the results do not look for tips to GL / gl.h file, we can only put up the OpenGL libraries are installed, do not know the operating right at a later time to consider it, let's start the installation
1, see the mesa relevant packages
yum List mesa *
2, install these packages
yum install mesa *
安装完成后，我们就拥有了一个基础的OpenGL开发环境了，但是仅仅有基础的开发环境是不够的，一般来讲，我们还要安装一个叫做Glut的库，这是一个OpenGL的辅助库，可以让我们创建与平台无关的OpenGL窗口。因此，安装Glut也是必要的。 Glut有很多种实现，在这里我用的是freeglut。
3、查看glut
yum list *glut*
4、安装freeglut
yum install freeglut*
到这里，我们就完成了OpenGL的安装了。
