Build Enviorment Set up :

This is a combination of the steps offered in the threads 'Compile JB on Ubuntu' and TeamChopsticks CyanogenMod.

Special thanks to dastin1015 and TeamChopsticks.

Tip: Allocate at least 75 gigs of space for the building of ONE ROM. If you install ccache, you will want 90. A complete build directory can use as much as 100 gigs, so make sure you have plenty of room. One of the ways to fail out a build is too use all of your partition before acquiring all the necessary files.

Here are the steps from those 2 tutorials in correct order:

0.1 ))

Install Gedit

# gedit
sudo apt-get install gedit

1) You need the following:

-JDK 6 if you wish to build Jellybean.

[COLOR="Black"]$ sudo apt-get oracle-java7-installer
-Python 2.4 -- 2.7, which you can download from python.org.[/COLOR]

Or:

[COLOR="black"]$ sudo apt-get install python
-Git 1.7 or newer. You can find it at git-scm.com.[/COLOR]

Or:

[COLOR="black"]$ sudo apt-get install git-core[/COLOR]

-Android SDK:

Download the SDK here: http://developer.android.com/sdk/index.html

Extract the SDK and place it in your home directory.

I renamed my SDK to android-sdk to make it easier to navigate to – this tutorial assumes you've done that as well.

Go to your home folder, press Ctrl+H to show hidden files, and open up your .bashrc file.

Add these lines at the bottom of the file:

[COLOR="black"]# Android tools
export PATH=${PATH}:~/android-sdk/tools
export PATH=${PATH}:~/android-sdk/platform-tools
export PATH=${PATH}:~/bin[/COLOR]

Find your .profile file and add this at the bottom of the file:

[COLOR="black"]PATH="$HOME/android-sdk/tools:$HOME/android-sdk/platform-tools:$PATH"
You have now successfully installed the Android SDK.[/COLOR]

To check for updates issue this into your terminal:

[COLOR="black"]$ android[/COLOR]

2) Install required packages. 64-bit (recommended)

[COLOR="black"]$ sudo apt-get install git-core gnupg flex bison gperf build-essential
zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs
x11proto-core-dev libx11-dev lib32readline-gplv2-dev lib32z-dev
libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown
libxml2-utils lzop schedtool[/COLOR]

On newer versions of Ubuntu such as 11.10 you may need to do the following:

[COLOR="black"]$ sudo ln -s /usr/lib/i386-linux-gnu/libX11.so.6 /usr/lib/i386-linux-gnu/libX11.so[/COLOR]

[COLOR="black"]$ sudo apt-get install git-core gnupg flex bison gperf build-essential
zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev
libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386
libgl1-mesa-dev g++-multilib mingw32 openjdk-6-jdk tofrodos
python-markdown libxml2-utils xsltproc zlib1g-dev:i386
$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so[/COLOR]

3) Configure your USB.

[COLOR="black"]$ gksudo gedit /etc/udev/rules.d/51-android.rules[/COLOR]

Inside of this blank text file insert:

4) Save the file and close it and then issue this command:

[COLOR="black"]$ sudo chmod a+r /etc/udev/rules.d/51-android.rules[/COLOR]

5) Install the repo:

[COLOR="black"]$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
$ chmod a+x ~/bin/repo[/COLOR]

Create your work directory:

[COLOR="black"]mkdir ~/"your directory name here" For example: mkdir ~/cm10
cd ~/cm10[/COLOR]

Setup local manifest:

[COLOR="Black"]mkdir .repo/local_manifests
touch .repo/local_manifests/semc.xml
gedit .repo/local_manifests/semc.xml[/COLOR]
