Android4.2模拟器kernel下载及编译-linux kernel3.4.0

======================================================================================================================================

一、源码下载

1.git clone https://android.googlesource.com/kernel/goldfish.git

2.cd goldfish/.git/

git branch -a

/*************************************************/
  *master     （*master表示当前在master分支）
  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
/*************************************************/

3.cd ../

git checkout -t origin/android-goldfish-3.4  -b goldfish

二、源码编译

1.产生配置文件

make ARCH=arm goldfish_armv7_defconfig

或cp arch/arm/configs/goldfish_armv7_defconfig .config

2.编译

make ARCH=arm  CROSS_COMPILE=/home/android/android-4.2/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6/bin/arm-linux-androideabi-

或vi Makefile

修改

#ARCH           ?= $(SUBARCH)
#CROSS_COMPILE  ?= $(CONFIG_CROSS_COMPILE:"%"=%)

为

ARCH    := arm
CROSS_COMPILE   := /home/android/android-4.2/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6/bin/arm-linux-androideabi-

完后make即可。

说明：以上路径为Android4.2中自带交叉编译器目录。
