Open-Source Licenses
The iDroid Project is an Open-Source Project. Android is under Apache License, version 2.0. As such, changes to the source code must be made public.
If you plan to compile Android with your own changes to the source code, please make your changes public. What you have changed may be helpful for the iDroid Project and for helping in troubleshooting.
If you don't have a git repo to put you changes, that's ok. You can always create a pastie of the diffs you've created, especially if only 1 line was changed.
Preparing your build system
The following instructions are for ubuntu 10.04
First you need to ensure you have the jaunty multiverse in your apt sources list (the required jdk version is not available in newer ubuntu versions)
sudo vi /etc/apt/sources.list
Add the following:
deb http://us.archive.ubuntu.com/ubuntu/ jaunty multiverse deb http://us.archive.ubuntu.com/ubuntu/ jaunty-updates multiverse
Update your apt-cache:
sudo apt-get update
Now onto installing required packages to build
x86_64
sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl sun-java5-jdk zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev
i386/i686
sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
Android repo tool. - All Platforms
cd ~ mkdir bin curl http://android.git.kernel.org/repo >~/bin/repo chmod a+x ~/bin/repo
Building
This procedure will download the source from all of the required repositories and then compile them. It would be a good idea to look through the Android guide listed above to prepare your machine before continuing. Note, however, that the compile instructions there are not for building iDroid sources.
mkdir froyo cd froyo repo init -u git://github.com/iDroid-Project/platform_manifest.git -b froyo-iphone repo sync . build/envsetup.sh && choosecombo
If the repo tool is not in your PATH, you will need to use 'repo-dir-path/repo' above instead of 'repo'.
Selections:
- device (1)
- release or debug (depends what you want)
- iPhone3G or iPhone2G or iPodTouch1G (depends what you want)
- eng
make -j2
- (-j = num of compile processes, 2 per core)
Wait for everything to compile and there you go.
