1. 下载安装svn客户端,例如TortoiseSVN。安装完后,svn执行目录自动被添加入系统环境变量PATH中。 2. 下载并安装msysgit和Tortoisegit msysgit下载地址:http://code.google.com/p/msysgit/downloads/list Tortoisegit下载地址:http://code.google.com/p/tortoisegit/downloads/list 选择适合自己系统的版本,下载并安装(注:Tortoisegit只是一个gui,必须安装msysgit) Tortoisegit安装时会找到git目录并自动配置好。把msysgit中bin目录手动添加到系统环境变量PATH中,比如我的目录是“D:/Program Files/Git/bin” 3. 下载并安装Python,建议安装Python2.6 下载地址:http://www.python.org/download/releases/2.6/。安装后Python执行目录自动被添加入系统环境变量PATH中。 4. 下载并配置depot_tools     建立一个存放depot_tools的目录,command进入该目录     svn co http://src.chromium.org/svn/trunk/tools/depot_tools     下载后把depot_tools目录手动添加到系统环境变量PATH中 5. 建立WebRTC的源码目录     比如E:/Developer/WebRTC/ 6. 打开cmd,进入第5步建立的源码目录 7. 执行:  gclient config https://webrtc.googlecode.com/svn/trunk         或者 gclient.bat config https://webrtc.googlecode.com/svn/trunk 8. 执行:  gclient sync –force (注意这里是两个- […]
