一、前言
目前因机器OS GCC版本太老，导致无法编译一些新版本软件，所以写了一个自动编译GCC的python脚本，操作系统是比较老的suse 10, 很多系统自动软件版本都很低，所以此脚本一般可适用目前比较流行的OS，大家可多尝试一下
二、机器环境
OS: SUSE 10 Bit: 64-bit python: 2.6
三、依赖软件
gmp: 4.3.2 mpc: 0.8.1 mpfr: 2.4.2 gcc: 4.4.0
四、安装脚本
1 目录结构
InstallGcc ---bin -----install_gcc.py ---conf ---tmp ---src -----gcc -------gmp-4.3.2.tar.gz -------mpc-0.8.1.tar.gz -------mpfr-2.4.2.tar.gz -------gcc-4.4.0.tar.gz
2 脚本如下：
