建立scons开发环境

概述

本文重点介绍win7环境下安装arm gcc编译器和scons编译系统的过程

注意：对于arm gcc和scons的介绍信息，请参考本博客《arm gcc简介》，《scons系统简介》

安装步骤

1. 安装gcc

这里采用launchapad的arm-none-eabi-gcc，官网https://launchpad.net/gcc-arm-embedded/
进入下载页面，根据自己的系统，选择对应的版本，我这里下载32位最新版4.9gcc-arm-none-eabi-4_9-2015q3-20150921-win32.exe

点击安装，一路next，保持默认安装路径，安装完成界面，会有4个复选框，勾选

Add path to environment variable
Add registry information
点击完成，arm gcc安装完成

2. 安装python 2.xx

注意: 一定要安装2.xx版本的python
进入python下载页面https://www.python.org/downloads/release/python-2710/，选择对应系统的python
这里选择32位2.7自安装包版本
https://www.python.org/ftp/python/2.7.10/python-2.7.10.msi

点击安装，一路next，保持默认安装路径和配置选项，直到安装完成

3. 安装scons

进入scons下载页面http://www.scons.org/download.php
下载2.4版本的windows安装包http://prdownloads.sourceforge.net/scons/scons-2.4.0-setup.exe

点击安装，一路next，保持默认安装路径和配置选项，直到安装完成

4. 更新环境变量

打开系统环境变量配置页

1	开始－》计算机－》属性－》高级系统设置－》环境变量－》系统变量－》Path－》编辑

检查Path是否有下面三项，没有则添加

1	C:\Python27;C:\Python27\Scripts;C:\Program Files\GNU Tools ARM Embedded\4.9 2015q3\bin

注意: Path 用;来分割路径

5. 测试系统

打开Cmd窗口，输入arm-none-eabi-gcc -v, python -V, scons -v
注意: python -V中的V要大写
