获取android源代码
To clone one of these trees, install git , and run:
git clone git://android.git.kernel.org/ + project path.
To clone the entire platform, install repo , and run:
mkdir mydroid
cd mydroid
repo init -u git://android.git.kernel.org/platform/manifest.git
repo sync

打算全部下载回来再说，先下载repo脚本
更多git和repo使用说明看这里：
http://source.android.com/download/using-repo
curl http://android.git.kernel.org/repo >repo
chmod +x repo
wen@debian:~/android/source$ ./repo init -u git://android.git.kernel.org/platform/manifest.git

Getting repo ...
from git://android.git.kernel.org/tools/repo.git
wen@debian:~/android/source$ ./repo sync
和远程服务器同步，过程比较长，全部代码下来好几Gb
打算编译一个vmware虚拟机上能运行的
目前google已经出e pc支持的版本了
切换到cupcake 分支，master分支不是太稳定
$ repo init -u git://android.git.kernel.org/platform/manifest.git -b
cupcake
$ repo sync
同步后，很多的更改会uncommit
建立一个local_manifest.xml
$ vi ./.repo/local_manifest.xml
<manifest>
<project name="platform/vendor/asus/eee_701" path="vendor/asus/
eee_701"/>
</manifest>
$ repo sync
... A new repo command ( 1.8) is available.
... You should upgrade soon:
cp /home/invain/bin_x86/mydroid/.repo/repo/repo /home/invain/bin/

Ubuntu Linux (32-bit x86)
- Required Packages:
- Git 1.5.4 or newer and the GNU Privacy Guard.
- Git 1.5.4 or newer and the GNU Privacy Guard.
-
- JDK 5.0, update 12 or higher. Java 6 is not supported, because of incompatibilities with @Override.
- JDK 5.0, update 12 or higher. Java 6 is not supported, because of incompatibilities with @Override.
-
- flex, bison, gperf, libsdl-dev, libesd0-dev, libwxgtk2.6-dev (optional), build-essential, zip, curl.
$ sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl li b ncurses5-dev zlib1g-dev
- You might also want Valgrind, a tool that will help you find memory leaks, stack corruption, array bounds overflows, etc.
$ sudo apt-get install valgrind
- Intrepid ( 8.10) users may need a newer version of libreadline:
Device drivers / Network device support / Ethernet (10 or 100Mbit) / EISA, VLB, PCI and on board controllers / AMD PCnet32 PCI support
Device drivers / Graphics support / Support for frame buffer devices / VESA VGA graphics support
Device drivers / Graphics support / Console display driver support / Framebuffer Console support
Device drivers / Graphics support / Console display driver support / Select Compiled-in fonts (VGA 8x8 font, VGA 8x16 font)
，再把這些取消：
Device drivers / Real Time Clock / Android alarm driver
Device drivers / Misc devices / Android pmem allocator
，然後重新建置 kernel：make bzImage。
編譯好之後，把 arch/x86/boot/bzImage 複製為 mydroid/vendor/asus/eee_701/kernel。
TARGET_ARCH=x86 TARGET_PRODUCT=eee_701 DISABLE_DEXPREOPT= true make -j2 installer_img CC=gcc CXX=g++
出现错误
No rule to make target `vendor/google/frameworks/maps/com.google.android.maps.xml'
把eee_701.mk中的 'generic_with_google.mk' 改为 'generic.mk'
编译遇到新错误
其他用户编译会提示没有找到e2fschk
这里不能简单的把文件从sbin目录复制到bin目录 否则会和root用户编译一样 出现下面的错误
Copy: out/target/product/eee_701/installer/root/system/bin/netcfg

android目录下的external/e2fsprogs 就是这些工具，没有编译而已
打下面的patch
project external/e2fsprogs/
diff --git a/Android.mk b/Android.mk
index e71cf08..3d39a41 100644
--- a/Android.mk
+++ b/Android.mk
@@ -1,3 +1,3 @@
-ifneq ($(TARGET_SIMULATOR),true)
-# include $(call all-subdir-makefiles)
+ifeq ($(TARGET_ARCH),x86)
+include $(call all-subdir-makefiles)
endif
这样e2fsprogs下面的工具就编译好了，可以在out/target/
