Android Linux内核编译

平台：

Wind7_64 + Ubuntu12_04_64 + VMware

 

这里以Android5.0为例：

Android5.0的编译可以参考：

遇到的问题

需要使用openjdk7

apt-get install openjdk-7-jdk apt-get install openjdk-7-jre

编译：

root@ubuntu:~/work/android/android5/android-5.0# . build/envsetup.sh including device/moto/shamu/vendorsetup.sh including device/samsung/manta/vendorsetup.sh including device/generic/mini-emulator-x86/vendorsetup.sh including device/generic/mini-emulator-arm64/vendorsetup.sh including device/generic/mini-emulator-mips/vendorsetup.sh including device/generic/mini-emulator-x86_64/vendorsetup.sh including device/generic/mini-emulator-armv7-a-neon/vendorsetup.sh including device/lge/mako/vendorsetup.sh including device/lge/hammerhead/vendorsetup.sh including device/asus/tilapia/vendorsetup.sh including device/asus/deb/vendorsetup.sh including device/asus/grouper/vendorsetup.sh including device/asus/flo/vendorsetup.sh including device/asus/fugu/vendorsetup.sh including sdk/bash_completion/adb.bash root@ubuntu:~/work/android/android5/android-5.0# choosecombo Build type choices are: 1. release 2. debug Which would you like?

编译完成后，设置工具链路径，为编译内核方便：

export PATH=$PATH:/root/work/android/android-5.0/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin

编译内核：

下载内核后，解压

root@ubuntu:~/work/android/android5/goldfish# git branch -a master remotes/origin/HEAD -> origin/master remotes/origin/android-3.10 remotes/origin/android-3.4 remotes/origin/android-goldfish-2.6.29 remotes/origin/android-goldfish-3.10 remotes/origin/android-goldfish-3.4 remotes/origin/linux-goldfish-3.0-wip remotes/origin/master

由于Android5.0的模拟器使用的内核是3.4（可以用模拟器自带的内核启动一个模拟器，然后看一下内核版本 cat /proc/version ）， 所以我们也是用3.4:

root@ubuntu:~/work/android/android5/goldfish# git checkout remotes/origin/android-goldfish-3.4 -b linux-3.4

然后修改Makefile

ARCH        ?= arm CROSS_COMPILE ?= arm-eabi-

配置内核

root@ubuntu:~/work/android/android5/goldfish# make goldfish_armv7_defconfig

注意：这个默认的内核并没有配置模块加载功能，需要执行make menuconfig设置，否则无法编译和加载内核模块

编译内核

make zImage -j2

用我们编出的内核启动模拟器：

root@ubuntu:~/work/android/android5/android-5.0# emulator64-arm -kernel ../goldfish/arch/arm/boot/zImage
