HOWTO Build Android-X86 Full Source
====================================
Last Modified on 23-Dec-2008 23:10
I Summarized how to build android full source for x86 target.
0. My development environments
- OS : Ubuntu 8.10 Distribution ( 2.6.27-4-generic )
- CPU: Intel(R) Core(TM)2 Duo CPU T5750 @ 2.00GHz ( Samsung SENS
R60 Laptop )
- RAM: Samsung DDR Ram
- Target: Eee PC (ASUS)
1. Query of Linux distribution information
- At first, Prepare ASUS Eee 701 Lattop or Samsung nettop (NC01).
And then, confirm system information on your linux distribution
like belows.
$ uname -a
Linux invain-laptop 2.6.27-4-generic #1 SMP Wed Sep 24 01:30:51 UTC
2008 i686 GNU/Linux
$ gcc --version
gcc (Ubuntu 4.3.2-1ubuntu10) 4.3.2

PURPOSE.
2. repo init and Sync
- You have to download android full source for x86 architecture like
ASUS Eee PC 701.
- Eee pc dev tree is "git://android.git.kernel.org/platform/vendor/
asus/eee_701.git".
$ cd ~
$ mkdir bin_x86 && cd bin_x86
$ mkdir mydroid && cd mydroid
$ repo init -u git://android.git.kernel.org/platform/manifest.git -b
cupcake
$ repo sync
$ vi ./.repo/local_manifest.xml
<manifest>
<project name="platform/vendor/asus/eee_701" path="vendor/asus/
eee_701"/>
</manifest>
$ 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/
repo
