How to compile CM11 by Andromadus Team

Make your 'own' KitKat-ROM today!

Thank you note: Thanks very much Andromadus Team ([MENTION=4350964]Flinny[/MENTION] [MENTION=1270461]NeverGone\RU[/MENTION] ) for the awesome work bring the kitkat for our device

I. Preparation

Things you need for building:

A computer

An internet connection

An open mind

Time

Patience

First of all, you need a running up-to-date Ubuntu/Linux system. I am using Ubuntu 13.10 64-bit.

Use the terminal to make the steps. A terminal window can be opened by pressing Ctrl+Alt+T. Every single command for the terminal is marked with a $ sign. Just paste every command (without the $ sign) to your terminal window and there shouldn't be any problem.

IMPORTANT: INSTALL EVERYTHING AS A NORMAL USER. DON'T INSTALL AS ROOT!

II. Installation of the required packages (Ubuntu 13.10 64-bit)

Install packages:

$ sudo apt-get install bison build-essential curl flex \
g++-multilib gcc-multilib git-core gnupg gperf \
lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev \
libesd0-dev libncurses5-dev libsdl1.2-dev \
libwxgtk2.8-dev libxml2 libxml2-utils lzop \
openjdk-6-jdk openjdk-6-jre pngcrush schedtool \
squashfs-tools xsltproc zip zlib1g-dev

III. Installing Java

You need a version 6 Java Development Kit for building CM11.0. Usually, the SUN JDK 6 is recommended. But there is another way: you can use the OpenJDK 6. When you installed the required packages as described above, you will just need to configure your Java installation.

Check your Java version:

$ java -version

Verify the symlinks. Javac, Java, Javaws, Javadoc, Javah, Javap and Jar should all point to the right Java location and version:

$ ls -la /etc/alternatives/java* && ls -la /etc/alternatives/jar

If they are pointing to the wrong versions you have to change that to OpenJDK6.

Select the default Java version for your system:

$ sudo update-alternatives --config javac
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javaws
$ sudo update-alternatives --config javadoc
$ sudo update-alternatives --config javah
$ sudo update-alternatives --config javap
$ sudo update-alternatives --config jar

That's it.

IV. The sources

Install repo:

Repo is a tool that makes it quite easy to download and maintain the sources of Cyanogenmod.

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

Create the working directory:

$ mkdir ~/cm11
$ cd ~/cm11

Initialize Repo:

$ repo init -u git://github.com/Andromadus/android.git -b cm-11.0

and enter your credentials.

Download the sources:

$ repo sync -j# -f -c

Wait until it's finished - takes some time to download the hefty 12 GB of source code!

The -c command is evaluated through /bin/sh and any arguments after it are passed through as shell positional parameters.

Only use -f if you had a slow connection. This will force sync

The -j# command is for 'boos' the sync. The # is the number of cores of your pc + 1 (I use -j4)

Have a break, have a KitKat!

If the process hangs use Ctrl+C to break out of it and resume the download with another

If you are running into a lot of syncing errors the reason might be that the 'repo sync' command is establishing four threads automatically. This might be too much. So try to change the command to run with one thread only by using

$ repo sync -j1

Download the necessary prebuilts from cyanogenmod by running

$ cd ~/cm11/vendor/cm
$ . get-prebuilts
$ cd ../../

Initialize the environment

$ . build/envsetup.sh

Configure it for our device

$ lunch cm_vision-userdebug

And you're done!

V. Reduce the time of building [OPTIONAL]

This is reduce the time of your build, otherside will use more space.

Navigate to your home directory and type:

$ cd ~/cm11

$ export USE_CCACHE=1

$ export CCACHE_DIR=~/.ccache

$ prebuilts/misc/linux-x86/ccache/ccache -M 20G

The suggested ccache size is 20-100GB. The recomended is 20 GB, if you had a lots of space on your computer you can increase it to 100 GB

VI. Building the ROM

Now build it:

$ mka bacon

And the building process starts. Now have patience. Building takes around half an hour on fast systems and a lot more on older and slower machines.

When everything worked as it should you will find your new ROM-image in ~/cm11/out/target/product/vision

It is called cm-11-DATE-UNOFFICIAL-vision-zip. You can flash it via CWM/TWRP as usual.

VII. Rebuilding with newest sources

Whenever you like to update your sources and build a new version you have to run these four simple commands:

$ cd ~/cm11
$ repo sync
$ . build/envsetup.sh
$ lunch cm_vision-userdebug
$ mka bacon

Compiling takes less time than it took for creating the ROM the first time because it's only building new parts while reusing old parts that haven't changed.

Happy building!
