在x86的機器上編譯使用Andorid

看門狗

在X86的機器上編譯安裝android，做一個簡單快速的上網本.我的編譯環境為VMwave+ubuntu10.04，編譯時對內存占用很大，建議多分一點兒，我分了1.5G.參考網站：
android-x86官方網站：http://www.android-x86.org/
Google OS實驗室：http://blog.livedoor.jp/moonlight_aska/

一、編譯環境配置：

1、安裝必要組件
$ 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、安裝repo
$ cd ~
$ mkdir bin
$ curl http://android.git.kernel.org/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ export PATH=$PATH:~/bin

二、獲取android-x86源代碼
$ 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為制定版本，這里采用的是2.1-eclair來編譯的

三、開始編譯，一般機器采用eeepc的模式編譯。
$ cd android2.1
$ make iso_img TARGET_PRODUCT=eeepc

iso_img為打包為ISO鏡像，如果想打包為USB鏡像的話可以采用：
$ cd android2.1
$ make usb_img TARGET_PRODUCT=eeepc

錯誤修正：在編譯的過程中碰到了幾處錯誤，修改方法如下：

錯誤1、錯誤提示：

-LOCAL_LDLIBS += -lrt

endif

編譯成功后，可在out/target/product/eeepc/eeepc.iso找到ISO鏡像，用虛擬機載入該鏡像即可。

已知不完善的地方，gapps安裝后會FC，電子市場FC
