Android源码编译

源码下载

Android源码下载支持的系统目前只有Ubuntu和Mac OS两种操作系统, 本次以Ubuntu系统为例.

官方网站: http://source.android.com/source/downloading.html

下载单独项目的源码：https://github.com/android

• 下载Git(版本控制工具). 调出命令行: ctrl + alt + T
  sudo apt-get install git

• 安装curl(上传和下载数据的工具).
  sudo apt-get install curl

• 安装repo(repo其实是一个应python脚本对Git的封装，主要是为了简化下载Android源代码的步骤。).

    // 创建目录    mkdir ~/bin    // 下载repo脚本到本地bin文件夹下    curl http://android.git.kernel.org/repo >~/bin/repo      //官网：curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo    // 如果上面下载失败, 采用下面这种方式    curl "http://php.webtutor.pl/en/wp-content/uploads/2011/09/repo" >~/bin/repo    // 给所有用户追加可执行的权限    chmod a+x ~/bin/repo    //或chmod 755 ~/bin/repo    // 临时把repo添加到环境变量中, 方便后面执行.    // 注意: 每次重启ubuntu之后此环境变量失效, 重新配置就可以了.    export PATH=~/bin:$PATH    //注意: 若PATH出现错误导致shell无法正常使用，使用 export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin 即可。

• 创建文件夹, 用于存放下载的Android源码.
  mkdir ~/android_source
cd ~/android_source

• 初始化库.

  // 需要先配置git的用户信息
  git config --global user.email "[e-mail]"
git config --global user.name "wailaixing"

  repo init -u https://android.googlesource.com/platform/manifest -b android-2.3_r1

  // 如果上面初始化失败, 用下面的代码
  repo init -u git://codeaurora.org/platform/manifest.git -b gingerbread

  当屏幕出现以下信息表示成功初始化
  repo initialized in /home/shiyanqi/android_source

• 开始同步下载
  repo sync
  注意: 下载过程中, 因为网络问题, 可能会中断下载. 当中断下载时, 继续使用repo sync命令继续下载.

源码编译

在编译源码之前需要做一些准备操作

• 安装JDK

• 安装其他编译时依赖的软件.

    sudo apt-get install gnupg    sudo apt-get install flex    sudo apt-get install bison    sudo apt-get install gperf    sudo apt-get install zip    sudo apt-get install curl    sudo apt-get install build-essential    sudo apt-get install libesd0-dev    sudo apt-get install libwxgtk2.8-dev    sudo apt-get install libsdl-dev    sudo apt-get install lsb-core    sudo apt-get install lib32readline-gplv2-dev    sudo apt-get install g++-multilib    sudo apt-get install lib32z1-dev    sudo apt-get install libswitch-perl

注意: ubuntu自带的源中速度比较慢, 有些软件找不到, 所以需要修改为国内的源, 修改源步骤如下:
1. 备份ubuntu自带的源.
sudo cp /etc/apt/sources.list /etc/apt/sources.list.old
2. 修改源文件
sudo gedit /etc/apt/sources.list
3. 先删除所有内容, 然后把以下内容拷贝进去, 并保存.

保存之后, 更新数据源.
sudo apt-get update

• 开始编译, 在源码的目录下, 执行一下命令:
  cd ~/android_socure
make
