• 系统环境: Ubuntu 9.10, Kernel 2.6.31-14-generic, i686
• 网络环境: 学生公寓B区 中国电信宽带接入
• Date： 12/12/2009

安装必要的软件包

• 安装git-core, gnupg, sun-java5-jdk, flex, bison, gperf, libsdl-dev, libesd0-dev, libwxgtk2.6-dev, build-essential, zip, curl, libncurses5-dev, zlib1g-dev

  $ sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

本机当前源没有Package: sun-java5-jdk，为安装sun-java5-jdk，将当前源替换为以下Ubuntu 9.04的源

deb http://run.hit.edu.cn/ubuntu/ jaunty main restricted universe multiverse
deb-src http://run.hit.edu.cn/ubuntu/ jaunty main restricted universe multiverse
deb http://run.hit.edu.cn/ubuntu/ jaunty-updates main restricted universe multiverse
deb-src http://run.hit.edu.cn/ubuntu/ jaunty-updates main restricted universe multiverse
deb http://run.hit.edu.cn/ubuntu/ jaunty-backports main restricted universe multiverse
deb-src http://run.hit.edu.cn/ubuntu/ jaunty-backports main restricted universe multiverse
deb http://run.hit.edu.cn/ubuntu/ jaunty-security main restricted universe multiverse
deb-src http://run.hit.edu.cn/ubuntu/ jaunty-security main restricted universe multiverse

然后

$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk

安装sun-java5-jdk后，换回Ubuntu 9.10的源。 若希望系统使用sun-java5-jdk，首先获得root权限并使用命令

# update-alternatives --config java

然后，选择"/usr/lib/jvm/java-1.5.0-sun/jre/bin/java"这一项，使系统使用sun-java5-jdk。 可以用命令

$ java -version

查看系统当前使用的java版本

• 安装Valgrind: a tool that will help you find memory leaks, stack corruption, array bounds overflows, etc.

  $ sudo apt-get install valgrind

• 安装新版libreadline

  $ sudo apt-get install lib32readline5-dev

本机源无此Package, and Android Open Source Project says: 'Intrepid (8.10) users may need a newer version of libreadline'. 在网上只搜到了用于amd64平台的lib32readline5-dev.deb包。 这里有readline5的源代码，可以编译出lib32readline5-dev，有兴趣的可以试一下。笔者目前没有装lib32readline5-dev。(但是，可以使用$sudo apt-get install libreadline5-dev 安装libreadline5-dev。它与lib32readline5-dev 一样？笔者装了libreadline5-dev，目前不知道这是干嘛用的。)

安装Repo

For more information about Repo, see Using Repo and Git.

• 在用户主目录新建bin目录。

  $ cd ~
  $ mkdir bin

• 将该目录添加进PATH环境变量(在~/.bashrc末添加一行"PTAH=$PATH:$HOME/bin"，重新开个终端即可)
• 下载Repo脚本(下载完后可以用编辑器打开这个脚本爽一下)

  $ curl http://android.git.kernel.org/repo >~/bin/repo

• 给Repo脚本加上可执行权限

  $ chmod +x ~/bin/repo

初始化Repo客户端

输入

$ cd ~
$ mkdir yangdroid; cd yangdroid

下载Repo，下列命令将在"下载Android源码阶段"下载Android master version

$ repo init -u git://android.git.kernel.org/platform/manifest.git

下载其他版本的Android用-b选项，如

$ repo init -u git://android.git.kernel.org/platform/manifest.git -b cupcake

在提示符后输入用户名和Email(推荐使用gmail)。

下载Android源码

输入

$ repo sync

下载完后，Android源码将存放于~/yangdroid目录。

Verifying Git Tags

输入

$ gpg --import

粘贴下列Key至终端，回车并按Ctrl-D将Key导入GnuPG key database。
