To compile Kit-Kat 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.

You will need 25GB (or more) free to complete a single build, and up to 80GB (or more) for a full set of builds.

1) You need the following:

-JDK 6 if you wish to build Kit-Kat.

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update && sudo apt-get install oracle-java6-installer

-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

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 http://commondatastorage.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 -b android-4.4.4_r2

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

$ cd WORKING_DIRECTORY

AOSP:

$ repo init -b android-4.4.4_r2
$ 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 -b kitkat-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

~FIXES~

If you are running into issues such as:

Which would you like? [full-eng] 5
build/core/product_config.mk:209: *** No matches for product "full_d710". Stop.
Device d710 not found. Attempting to retrieve device repository from CyanogenMod Github (http://github.com/CyanogenMod).
Repository for d710 not found in the CyanogenMod Github repository list. If this is in error, you may need to manually add it to your local_manifest.xml.
build/core/product_config.mk:209: *** No matches for product "full_d710". Stop.

** Don't have a product spec for: 'full_d710'
** Do you have the right repo manifest?

What you need to do is to edit your blob to match the PRODUCT_NAME to the file name. For example with mine I have full_d710.mk therefore in this file I need to have PRODUCT_NAME to match it. Whatever error it is looking for you just need to change the PRODUCT_NAME line to match what the error shows.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If you run into issues with Java being the incorrect version here is the fix:

Make sure Java 6 JDK is installed by typing in:

$ java -version

Open the file main.mk in build/core and delete this line from the java error code section:

$(error stop)
