GCC源码自动编译-python脚本

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：
