android内核编译及模拟器运行过程记录

android内核是在前段时间下载的，由于之前android的源码没有编译成功，所以只是拿来看代码。今天把android的源码编过了，开始到kernel了。

在kernel目录查看版本情况：
[zzz@localhost goldfish]$ git branch -a
* (detached from origin/android-goldfish-3.4)
master
remotes/origin/HEAD -> origin/master
remotes/origin/android-3.10
remotes/origin/android-3.18
remotes/origin/android-3.4
remotes/origin/android-goldfish-2.6.29
remotes/origin/android-goldfish-3.10
remotes/origin/android-goldfish-3.10-l-mr1-dev
remotes/origin/android-goldfish-3.10-m-dev
remotes/origin/android-goldfish-3.18-dev
remotes/origin/android-goldfish-3.4
remotes/origin/android-goldfish-3.4-l-mr1-dev
remotes/origin/linux-goldfish-3.0-wip
remotes/origin/master

重新checkout 了3.4的goldfish的内核：
git checkout remotes/origin/android-goldfish-3.4
这个很快。

[gumh@localhost goldfish]$ make ARCH=arm goldfish_armv7_defconfig .config

configuration written to .config

make[1]: Nothing to be done for `.config’.

[zzz@localhost goldfish]$ make ARCH=arm CROSS_COMPILE=/home/gumh/opensource/android-src/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/bin/arm-linux-androideabi-

上面要说明一下，这个CROSS_COMPILE工具网上有些说要下载，我这边是看到在下载的android的源码的prebuilts目录下就自带了。

运行模拟器：

to the system image. Next time, try using ‘-sysdir -system ’ instead.

emulator: WARNING: system partition size adjusted to match image file (1536 MB > 200 MB)

emulator: WARNING: data partition size adjusted to match image file (550 MB > 200 MB)

等了很多（5，6分钟吧），看起来图片是这样的：

好像不成功的样子。。。。

再等多3分钟左右：

出来主界面了～～～～～～

操作一下，解锁进入主界面：

看一下联系人应用：

感觉还是不错的 ～～～

接下来可开始学习写hal层的代码，熟悉其流程了。
