Ubuntu9.10下擷取Android源碼

首先根據http://source.android.com/download網頁上的描述可知，源碼大概有2.1GB，需要6GB空間才能編譯，因為我是在虛擬機器上裝的Ubuntu9.10，所以虛擬機器至少要有10GB空間。粗體，底線部分是我安裝中遇到的一些問題，或者重點關注的地方

 

首先需要安裝開發環境，需要如下包：

• Required Packages:
  • Git 1.5.4 or newer and the GNU Privacy Guard. 

•  
  • JDK 5.0, update 12 or higher.  Java 6 is not supported, because of incompatibilities with @Override. //只能用JDK5，JDK6不能相容@Override

•  
  • flex, bison, gperf, libsdl-dev, libesd0-dev, libwxgtk2.6-dev (optional), build-essential, zip, curl.  

$ 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

• You might also want Valgrind, a tool that will help you find memory leaks, stack corruption, array bounds overflows, etc.//這個是幫你尋找記憶體漏洞，堆溢出，數組越界溢出的工具 

$ sudo apt-get install valgrind

 

 

Ubuntu9.10的安裝源已經沒有JDK5了，所以需要用到9.04的安裝源

修改/etc/apt/sources.list把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

update之後，用sudo apt-get install sun-java5-jdk 即可像以往一樣安裝java 1.5

安裝後的基本設定：
sudo update-alternatives --config java
sudo update-java-alternatives -s java-1.5.0-sun
這時候再用java -version就能看到java 1.5已經正常工作了

 

 

接下來就是安裝repo

To install, initialize, and configure Repo, follow these steps:

1. Make sure you have a ~/bin directory in your home directory, and check to be sure that this bin directory is in your path:
     $ cd ~
     $ mkdir bin
     $ echo $PATH
   
2. Download the repo script and make sure it is executable:
   $ curl http://android.git.kernel.org/repo >~/bin/repo$ chmod a+x ~/bin/repo

初始化repo

1. Create an empty directory to hold your working files: 
   $ mkdir mydroid
   $ cd mydroid
2. Run repo init to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest:
   $ repo init -u git://android.git.kernel.org/platform/manifest.git
   • If you would like to check out a branch other than "master", specify it with -b, like:
     $ repo init -u git://android.git.kernel.org/platform/manifest.git -b cupcake
3. When prompted, configure Repo with your real name and email address. If you plan to submit code, use an email address that is associated with a Google account. 
   

A successful initialization will end with a message such as
   repo initialized in /mydroid

Your client directory should now contain a .repo directory where files such as the manifest will be kept. 

 

 

 

擷取代碼

To pull down files to your working directory from the repositories as specified in the default manifest, run 

   $ repo sync  

For more about repo sync and other Repo commands, see Using Repo and Git.

The Android source files will be located in your working directory under their project names.

編譯代碼

To build the files, run make from within your working directory:
    $ cd ~/mydroid  
    $ make
If your build fails, complaining about a missing "run-java-tool", try setting the ANDROID_JAVA_HOME env var to $JAVA_HOME before making.  E.g.,
    $ export ANDROID_JAVA_HOME=$JAVA_HOME
