1. Linux發行版訊息
首先是驗證系統訊息
Fedora9$> uname -a

2. repo init 和 Sync 操作
- 首先下載Android for x86的完整源代碼。Eee pc 的 dev tree 在 “git://android.git.kernel.org/platform/vendor/asus/eee_701.git”.
Fedora9$> cd ~
Fedora9$> mkdir bin_x86 && cd bin_x86
Fedora9$> mkdir mydroid && cd mydroid
Fedora9$> repo init -u git://android.git.kernel.org/platform/manifest.git
-b cupcake
Fedora9$> repo sync
Fedora9$> vi ./.repo/local_manifest.xml
Fedora9$> 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/

3. 構建 x86 android
Fedora9$> export PATH=$PATH:/usr/sbin:/sbin (to use /sbin/tune2fs
command of e2fsprogs pack )
Fedora9$> TARGET_ARCH=x86 TARGET_PRODUCT=eee_701 DISABLE_DEXPREOPT=true CC=gcc34 CXX=g++34 make -j2 installer_img

…………… Below Omission ……………….
* 在構建中可能遇到一些問題,解決辦法是
- 用低版本gcc 替換 gcc-4.3 version. Ubuntu 8.04LT用的是GCC 4.2, Ubuntu 8.10是GCC 4.3,所以推荐用8.04來做build
- 如果你正在使用 GCC 4.3, 請照下面修改源代碼中的相關頭文件:
Fedora9$> vi external/srec/tools/thirdparty/OpenFst/fst/lib/../../fst/
lib/vector-fst.h
Fedora9$> vi external/srec/tools/thirdparty/OpenFst/fst/lib/symbol-
table.cpp
Fedora9$> vi frameworks/base/tools/aidl/aidl.cpp –> #include
, #include
等等。
- Lim,GeunSik使用的是gcc 3.4
#> yum install compat-gcc*
#> rpm -qa grep compat-gcc

4. 制作USB Pen Disk安裝包
- 在BIOS中把第一啟動設備設置成USB,然後
Fedora9$> dd if=out/target/product/eee_701/installer.img of=/dev/your_usb_disk(例如/dev/sda1)
好了,接下來可以用你的android USB Pen Disk來嘗試啟動了。Enjoy it。
最後友情提示一句,我還沒有試這種方法,不過反正也不會破壞什麼,有興趣的朋友可以試一下。
