To compile Lollipop on Ubuntu I'm going to first give you steps to set up your computer to get this thing rolling.

You MUST be running a 64 bit version of Ubuntu, 32 bit is not supported.

This will NOT make a fully functional ROM, but will give you a place to start. Also I CANNOT fix every error you run into.

READ the entire OP and make sure to properly follow instructions. Don't forget to search the thread as your question may have already been answered.

Please use Pastebin for all errors you run into. Posting a link is much easier than a long list of errors in the thread. Thank you.

Source is roughly 8.5GB in size and you will need over 30GB (or more) free to complete a single build, and up to 100GB (or more) for a full set of builds.

1) You need the following:

-JDK 7 if you wish to build Lollipop.

$ sudo apt-get update
$ sudo apt-get install openjdk-7-jdk

Optionally, update the default Java version by running:

$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac

If you encounter version errors for Java, then it could be:

Failing to install the correct JDK

Another JDK previously installed appearing in your path. Prepend the correct JDK to the beginning of your PATH or remove the problematic JDK

-Python, which you can download from python.org. Or:

$ sudo apt-get install python

-Git, which you can find it at git-scm.com. Or:

$ sudo apt-get install git-core

-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.

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:

# Android tools
export PATH=${PATH}:~/android-sdk/tools
export PATH=${PATH}:~/android-sdk/platform-tools
export PATH=${PATH}:~/bin

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

PATH="$HOME/android-sdk/tools:$HOME/android-sdk/platform-tools:$PATH"

You have now successfully installed the Android SDK.

To check for updates issue this into your terminal:

$ android

3) Configure your USB.

$ gksudo gedit /etc/udev/rules.d/51-android.rules

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

$ sudo chmod a+r /etc/udev/rules.d/51-android.rules

4a) [OPTIONAL] Setting up ccache

You can optionally tell the build to use the ccache compilation tool. Ccache acts as a compiler cache that can be used to speed-up rebuilds. This works very well if you do "make clean" often, or if you frequently switch between different build products.

Put the following in your .bashrc or equivalent.

export USE_CCACHE=1

By default the cache will be stored in ~/.ccache. If your home directory is on NFS or some other non-local filesystem, you will want to specify the directory in your .bashrc as well.

export CCACHE_DIR=<path-to-your-cache-directory>

The suggested cache size is 50-100GB. You will need to run the following command once you have downloaded the source code:

prebuilts/misc/linux-x86/ccache/ccache -M 50G

This setting is stored in the CCACHE_DIR and is persistent.

5) Install the repo:

$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

6) Initialize the repo:

$ mkdir WORKING_DIRECTORY
$ cd WORKING_DIRECTORY

6a) For AOSP:

$ repo init -u https://android.googlesource.com/platform/manifest.git -b android-5.1.1_r13

6.1) For people who have already done a repo init:

$ cd WORKING_DIRECTORY

AOSP:

$ repo init -b android-5.1.1_r13
$ repo sync

7) When prompted, enter your real name and email address.

8) Gather the files:

$ repo sync

9) Continue onto adding a device

~How To Add A Device To The List~

1) Find the github for your device you wish to add. (For me it is the Asus Nexus 7 (2013) [codename: flo]

2) Now navigate to the location you are going clone the device tree to:

$ cd WORKING_DIRECTORY/device
$ mkdir asus

3) Clone the github device tree from remote to local: (The name after the branch would be whatever you want that folder to be named so make sure it is whatever standard name would be for your device, example: Nexus One [passion], Nexus S [crespo], Motorola Droid [sholes], HTC Incredible [inc], etc.)

$ git clone https://android.googlesource.com/device/asus/flo.git -b lollipop-dev flo

4) Now navigate into the folder:

$ cd flo

5) Connect phone to computer and make sure USB debugging is enabled and you have adb set up.

6) Extract Device Proprietary Files (if extract script is present):

$ ./extract-files.sh

Or:

./proprietary-files.sh

Or: See use your device's provided proprietary blobs (like flo): Download the binaries from: https://developers.google.com/android/nexus/drivers

Extract the blobs and place them in the directory from the root of your working directory (ex. vendor/asus/flo): vendor/MANUFACTUROR/CODENAME

7) Navigate back to your home directory for building:

$ cd ~/WORKING_DIRECTORY

8) Prepare To Compile:

$ source build/envsetup.sh

Or:

$ . build/envsetup.sh

9) Get your list of devices:

$ lunch

10) Pick your poison.

11) Now compile ('#' being the number of cores in your processor +1):

$ make -j#

Or for a flashable zip:

$ make -j# otapackage
