How to set up the JetDroid build environment [rev 1.3]

[Dopi]

There are currently two ways to set up a JetDroid build environment. This post describes the first method using all souces from the github source repositories. The second method based on source archives from the download section of the google code project site will be decribed in another post.

For obtaining a complete build environment the following things are neccessary:

• A Linux system
• Root access to install the neccessary tools

Next these steps neeed to be performed:

1. Install the neccessary software packages
2. Install + setup repo
3. Setup your working directories
4. Fetch the sources

Here are the detailed instructions to perform these steps:

Install the neccessary software packages

1. Open a terminal and run the following comands to install the various tools you will need.
   

   Code: Select all

   sudo aptitude install git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev ncurses-dev libc6-dev-i386 libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind


Install + setup repo

1. Make sure you have a /bin directory in your /home directory
   

   Code: Select all

   cd ~/
mkdir bin
echo $PATH


   
   
   You should see something like ':/home/user_name/bin:' in a line of text. If you don't see this, try restarting your computer or add it to your path (in case you are using the bash shell) by executing
   
   

   Code: Select all

   echo "export PATH=$PATH:$HOME/bin" >>~/.bashrc


   
   
   and restarting your terminal. (we should admit that adding a user writable directory into the path may decrease your computer security)
   
2. Download repo and make it executable
   

   Code: Select all

   curl http://android.git.kernel.org/repo >~/bin/repo
chmod a+x ~/bin/repo


Setup your working directory

1. Run these command to create the working directories
   

   Code: Select all

   mkdir JetDroid
cd JetDroid


Fetch the sources

1. Fetch the platform souce. These files are needed even if you only want to compile the bootloader or the kernel as it contains the cross-compiling tools.
   

   Code: Select all

   mkdir JetPlatform
cd JetPlatform
repo init -u git://github.com/JetDroid/JetPlatform_manifest.git -b eclair
repo sync
cd ..


   
   
2. Now fetch the kernel source. The kernel sources are needed to compile the bootloader.
   

   Code: Select all

   git clone git://github.com/Dopi/JetKernel.git JetKernel
cd JetKernel
git pull origin testing-2.6.29
cd ..


   
   
3. After this you can fetch the bootloader source
   

   Code: Select all

   git clone git://github.com/Dopi/JetQi.git JetQi
cd JetQi
git pull origin testing
cd ..


   
   
4. Finally you need to create two symbolic links
   

   Code: Select all

   ln -s JetKernel linux
ln -s JetPlatform/source android


Now your done! Happy compiling!
