下载编译goldfish内核

1、下载代码

mkdir down

cd down
git clone https://android.googlesource.com/kernel/goldfish.git
git branch -a
git checkout remotes/origin/android-goldfish-2.6.29 -b goldfish

2、指定编译器路径和前缀

export PATH=/home/derek/ics/ics-4.0.4/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:$PATH

export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=arm-eabi-

3、编译内核

cd goldfish
make goldfish_defconfig //wrong, for (Android2.3)
make goldfish_armv7_defconfig  （Android4.0）
make

4、在模拟器中使用新内核

ANDROID_PRODUCT_OUT=~/ics/ics-4.0.4/out/target/product/generic

ANDROID_PRODUCT_OUT_BIN=~/ics/ics-4.0.4/out/host/linux-x86/bin

export PATH=${PATH}:${ANDROID_PRODUCT_OUT_BIN}:${ANDROID_PRODUCT_OUT};

cd ~/ics/ics-4.0.4

emulator-arm -kernel /home/derek/down/goldfish/arch/arm/boot/zImage -sysdir ./out/target/product/generic -system system.img -data userdata.img -ramdisk ./out/target/product/generic/ramdisk.img -memory 200 -skindir ./out/host/linux-x86/platforms/android-15/skins -skin HVGA &
