ａｎｄｒｏｉｄ４．０ 编译

http://android-sz.iteye.com/blog/1265613

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
