Android获取源代码、编译、命令

核心提示：显示所有head分支：$ git branch -a显示* android-2.6.27remotes/origin/HEAD -> origin/android-2.6.27remotes/origin/android-2.6.25remotes/origin/android-2.6.27remotes/ori

显示所有head分支：

$ git branch -a

显示

* android-2.6.27

remotes/origin/HEAD -> origin/android-2.6.27

remotes/origin/android-2.6.25

remotes/origin/android-2.6.27

remotes/origin/android-2.6.29

remotes/origin/android-goldfish-2.6.27

remotes/origin/android-goldfish-2.6.29

我们选取最新的android-goldfish-2.6.29，其中goldfish是android的模拟器模拟的CPU。

$ git checkout -b android-goldfish-2.6.29 origin/android-goldfish-2.6.29

$ git branch

显示

android-2.6.27

* android-goldfish-2.6.29

我们已经工作在android-goldfish-2.6.29分支上了。

d)设定交叉编译参数

打开kernel目录下的Makefile文件，把CROSS_COMPILE指向刚才下载的prebuilt中的arm-eabi编译器

CROSS_COMPILE ?= arm-eabi-

把

LDFLAGS_BUILD_ID = $(patsubst -Wl$(comma)%,%,

$(call ld-option, -Wl$(comma)?build-id,))

这一行注释掉，并且添加一个空的LDFLAGS_BUILD_ID定义，如下:

LDFLAGS_BUILD_ID =

e)编译内核映像

$ cd ~/android/kernel

$ make goldfish_defconfig

$ make

f)测试生成的内核映像

$ emulator -avd myavd -kernel ~/android/kernel/arch/arm/boot/zImage
