编译android源码一（设置环境）

环境信息:

Ubuntu：v 12.04

Vmware 6.7

具体步骤:

1 . 初始化编译环境

设置编译环境：

安装Python 2.6 -- 2.7 命令:sudo apt-get install python-setuptools

参考：http://pymcu.com/Installation.html#LinInstall

安装成功验证命令: python --version

安装GNU Make 3.81 -- 3.82 命令:sudo apt-get install build-essential

参考：https://help.ubuntu.com/community/InstallingCompilers

安装成功验证命令: make --version

安装JDK 6
命令:http://blog.csdn.net/luhuajcdd/article/details/8777926

参考：http://www.liberiangeek.net/2012/07/download-and-install-sun-java-6-7-in-ubuntu-12-04-precise-pangolin-easily-with-this-script/

安装成功验证命令: java -version

安装Git 1.7 or newer
命令:sudo apt-get install git

参考：https://www.digitalocean.com/community/articles/how-to-install-git-on-ubuntu-12-04

安装成功验证命令: git --version

2.安装必须的软件(

Ubuntu 12.04

)

sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libglapi-mesa:i386  libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386

sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

3. 配置USB访问

文件位置:/etc/udev/rules.d/51-android.rules



内容:

# adb protocol on passion (Nexus One)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e12", MODE="0600", OWNER="<username>"

SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee0", MODE="0600", OWNER="<username>"

<username>要换成真正需要访问USB的用户名字。

4. 设置ccache

在~/.bashrc中添加：

export USE_CCACHE=1

缓存大小建议在50 - 100 GB。下载了源代码需要运行以下命令（适用于4.0或者之后的版本）:

prebuilts/misc/linux-x86/ccache/ccache -M 50G
