进过几天的等待，几经波折终于把android 4.0 的代码下载下来。（http://android-sz.iteye.com/blog/1259206）
终于可以编译了，期待……
编译环境：
1,系统: Ubuntu 10.10 (64bit)
2,Jdk: java (64bit)
3,交叉编译链: 自带
为了避免编译过程中出现错误，执行如下命令安装下面软件
$:sudo apt-get install zlib1g-dev lib64z1-dev bison flex libncurses5-dev libgl1-mesa-dev gperf gnupg zip libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential
个人习惯，修改一些配置文件。减少系统语言的种类，设置系统显示的样式及设置jdk变量。

做完上面几步，可以开始编译了……
1, 配置编译环境
SOURCE_PATH$:source ./build/envsetup.sh
执行了下面几个文件
including device/samsung/maguro/vendorsetup.sh
including device/samsung/tuna/vendorsetup.sh
including device/ti/panda/vendorsetup.sh
including sdk/bash_completion/adb.bash
2, 设置编译选项
SOURCE_PATH$:lunch
You're building on Linux
Lunch menu... pick a combo:
1. full-eng
2. full_x86-eng
3. vbox_x86-eng
4. full_maguro-userdebug
5. full_tuna-userdebug
6. full_panda-eng
Which would you like? [full-eng] 1
============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=4.0.1
TARGET_PRODUCT=full
TARGET_BUILD_VARIANT=eng
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=arm
TARGET_ARCH_VARIANT=armv7-a
HOST_ARCH=x86
HOST_OS=linux
HOST_BUILD_TYPE=release
BUILD_ID=ITL41D
============================================
呵呵，可以看到平台的配置。
3,开始编译
SOURCE_PATH$:make -j4
启用4线程编译吧!
等待中 …………
足足编译了4个小时，中间遇到磁盘不足。各位大能记得预留足够的磁盘空间。
终于编译完了。是不是迫不及待想看看效果呢？
4, 执行自己编译出来的android 4.0 吧！
设置sdk环境变量
SOURCE _PATH$:export PATH=~/Android/out/host/linux-x86/sdk/android-sdk_eng.root_linux-x86/tools:$PATH
执行编译出来的img
SOURCE_PATH$: $OUT/emulator -system system.img -data userdata.img -ramdisk ramdisk.img
5, 图出来咯
启动
进入系统
查看一下编译信息
ok 大功告成！
可以更深一步研究Android 4.0
