下載編譯Android內核主要可參考：http://source.android.com/source/building-kernels.html
創建工作目錄後，在工作目錄下運行git命令下載指定版本內核：
$ mkdir yourworkdir
$ cd yourworkdir
$ git clone https://android.googlesource.com/kernel/goldfish.git
https連接有問題的話改用http連接試試，https是加密數據協議，在國內會被屏蔽，http是明文協議沒什麼問題。
$ git clone http://android.googlesource.com/kernel/goldfish.git
執行結果可能如下：

remote: Finding sources: 100% (150/150)

其他可以下載的版本列表如下：

|---|---|---|---|
| flo | device/asus/flo-kernel/kernel | kernel/msm | flo_defconfig |
| deb | device/asus/flo-kernel/kernel | kernel/msm | flo_defconfig |
| manta | device/samsung/manta/kernel | kernel/exynos | manta_defconfig |

完成後當前目錄下會出現goldfish目錄，進入goldfish目錄，運行git branch -a命令，列出可抓取的分支版本，結果可能如下。
$
git branch -a
* (no branch)
master
remotes/origin/HEAD -> origin/master
remotes/origin/android-goldfish-2.6.29
remotes/origin/android-goldfish-3.4
remotes/origin/linux-goldfish-3.0-wip
remotes/origin/master
運行git checkout
git checkout -b android-goldfish-2.6.29 /origin/android-goldfish-2.6.29
標記分支可以選用git branch -a命令獲得列表中的任何一個。
編譯之前，配置與編譯有關的環境變量，如果安裝過android SDK，可以在SDK目錄下指定gcc預編譯命令路徑
$ export PATH=$(pwd)/prebuilts/gcc/darwin-x86/arm/arm-eabi-4.6/bin:$PATH
如果沒有安裝過，可以通過git下載一個
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6
設置 ARCH，SUBARCH，CROSS_COMPILE。
$ export ARCH=arm
$ export SUBARCH=arm
$ export CROSS_COMPILE=arm-eabi-
編譯配置
$ make menuconfig
編譯
$ make
