如何在Linux系统中安装gcc
身为菜鸟的我，最近准备复习一遍C语言，之前都是在VS上运行C程序的，现在想在linux环境下进行编程联系。众所周知，gcc是C语言最原始的编译器。所以，安装gcc是必要的。
我是在虚拟机上运行Linux的，先说说我的简单配置：用的是CentOS5.3 64位的系统，内核版本号为2.6.18-128.el5，该Linux系统没有预装gcc，我们可以用yum命令来安装gcc。
安装命令
yum install gcc安装过程如下

* updates: mirrors.opencas.cn
* addons: mirrors.btte.net
* extras: mirrors.opencas.cn
