```
$ wget https://raw.githubusercontent.com/racaljk/hosts/master/hosts -qO /tmp/hosts
$ sudo sh -c 'cat /tmp/hosts > /etc/hosts'
```
配置环境
sudo apt-get install gedit git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev pngcrush schedtool libxml2 libxml2-utils xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev gcc-multilib maven tmux screen w3m ncftp ccache pngquant maven
创建bin目录并指定路径，下载repo并赋予读写权限
$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl https://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
创建工作目录，初始化同步源码环境，开始同步
$ mkdir ~/sudamod
$ cd ~/sudamod
$ repo init -u git://github.com/SudaMod/android.git -b sm-2.0 --no-repo-verify
$ repo sync -c -f -j8 --force-sync --no-clone-bundle
设置编译缓存空间
$ echo "export USE_CCACHE=1" >> ~/.bashrc
$ ~/sudamod/prebuilts/misc/linux-x86/ccache/ccache -M 50G
开始编译
$ cd ~/sudamod
$ . build/envsetup.sh
$ breakfast "device name"
$ brunch "device name"
查看编译完成的刷机包
$ cd ~/sudamod/out/target/product/
再次编译，先清理，再同步更新
$ cd ~/sudamod
make clean
repo sync -j 16
