python练习贴06 为MinGW配置环境变量

继吉

　　运行MinGW
有一个"Automated MinGW Installer", 运行他的时候，会提示我下载一堆东西。
　　因为我的网络环境比较恶劣（公司下载会比较麻烦），
　　所以我现在使用的还是C同学当年给我的版本：MinGW3.1.0. 对应的gcc版本是3.2.3。
　　他只有一个安装文件，一顿下一步全都搞定（事实上他只有14M，我已经把它放到了我的邮箱里面）
　　然而他也存在着一个不方便的地方，就是安装完后需要手动配置环境变量。需要做的配置大体如下：

set PATH=%PATH%;D:\DevelopingTools\MinGW\bin
set LIBRARY_PATH=D:\DevelopingTools\MinGW\lib
set C_INCLUDE_PATH=D:\DevelopingTools\MinGW\include
set CPLUS_INCLUDE_PATH=D:\DevelopingTools\MinGW\include\c++\3.2.3;D:\DevelopingTools\MinGW\include\c++\3.2.3\\mingw32;D:\DevelopingTools\MinGW\include\c++\3.2.3\backward;D:\DevelopingTools\MinGW\include
 　　一次两次还好，每次都这么配置便有点麻烦。于是参照这篇blog: python练习贴03 修改注册表
。
　　写了段为MinGW配置环境变量的python代码。如下：

#! /usr/bin/python
# MinGW Version:  3.2.3
# --- use this script to set environment value as following: ---
# set PATH=%PATH%;D:\DevelopingTools\MinGW\bin
# set LIBRARY_PATH=D:\DevelopingTools\MinGW\lib
# set C_INCLUDE_PATH=D:\DevelopingTools\MinGW\include
# set CPLUS_INCLUDE_PATH=D:\DevelopingTools\MinGW\include\c++\3.2.3;D:\DevelopingTools\MinGW\include\c++\3.2.3\\mingw32;D:\DevelopingTools\MinGW\include\c++\3.2.3\backward;D:\DevelopingTools\MinGW\include
