在x86的机器上编译使用Andorid

在X86的机器上编译安装android，做一个简单快速的上网本.我的编译环境为VMwave+ubuntu10.04，编译时对内存占用很大，建议多分一点儿，我分了1.5G.参考网站：
android-x86官方网站：http://www.android-x86.org/
Google OS实验室：http://blog.livedoor.jp/moonlight_aska/

一、编译环境配置：

1、安装必要组件
$ sudo apt-get update
$ sudo apt-get -y install git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind

2、安装repo
$ cd ~
$ mkdir bin
$ curl http://android.git.kernel.org/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ export PATH=$PATH:~/bin

二、获取android-x86源代码
$ mkdir android2.1
$ cd android2.1
$ repo init -u git://git.android-x86.org/platform/manifest.git -b eclair-x86
$ repo sync

-b eclair-x86为制定版本，这里采用的是2.1-eclair来编译的

三、开始编译，一般机器采用eeepc的模式编译。
$ cd android2.1
$ make iso_img TARGET_PRODUCT=eeepc

iso_img为打包为ISO镜像，如果想打包为USB镜像的话可以采用：
$ cd android2.1
$ make usb_img TARGET_PRODUCT=eeepc

错误修正：在编译的过程中碰到了几处错误，修改方法如下：

错误1、错误提示：
