[GUIDE CM11] How to build your own CyanogenMod 11.0 ROM from sources for the Nexus 4

Raum1807 · Nov 8, 2013

Make your 'own' KitKat-ROM today!

V1.1 - 20131108 Update 1: Java part added. Error remarks. Local_manifest: branch update.
V1.0 - 20131106 Initial release

Thank you note: Thank you to the whole CM-Team for bringing up-to-date-Android to so many devices.

Overview

I. Preparation
II. Installation of the required packages
III. Installing Java
IV. The sources
V. Building the ROM
VI. Rebuilding with newest sources

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:

Code:

$ 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:

Code:

$ java -version

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

Code:

$ 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:

Code:

$ 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.

Code:

$ 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:

Code:

$ mkdir ~/cm11
$ cd ~/cm11

Initialize Repo:

Code:

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

and enter your credentials.

Download the sources:

Code:

$ repo sync

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

Have a break, have a KitKat!

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

Code:

$ repo sync

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

Code:

$ repo sync -j1

Initialize the environment

Code:

$ . build/envsetup.sh

Obtain the proprietary files:

First get two missing repositories for the Nexus 4 by running

Code:

$ breakfast mako

Then create a file with the name local_manifest.xml in the local_manifests directory. To see this directory, you have to press Ctrl-H in your file manager.

Use this code

Code:

$ gedit ~/cm11/.repo/local_manifests/local_manifest.xml

Update: Branch revision is now cm-11.0
Paste the following lines to the editor

Code:

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
  <project name="TheMuppets/proprietary_vendor_lge.git" path="vendor/lge" remote="github" revision="cm-11.0"/>
</manifest>

Save the file.

Run

Code:

$ repo sync

again to get the files needed.

Download the necessary prebuilts from cyanogenmod by running

Code:

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

And you're done!

V. Building the ROM

Now build it:

Code:

$ brunch mako

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.

Update 20131108: The errors from 20131106 are gone now. If you made the changes revert them, sync the repo and then brunch again. There is no need to edit the source at the moment.

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

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

VI. Rebuilding with newest sources

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

Code:

$ cd ~/cm11
$ repo sync
$ . build/envsetup.sh
$ brunch mako

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!

Nice Tutorial, thank you for the work :good:

Now i have to organize a linux-computer... :/

Thank you for your post. I knew how to compile but I was lazy to compile for myself any rom until now. I planned to wait until someone will post it, but your post just got me excited and I will compile.

Thank you for your instructions and all. Good luck!

This is what I keep getting...

If you have a quite new PC running Windows, you could use a virtual machine to install Linux ontop of your Windows installation. Have a look at VirtualBox for example. It's free. https://www.virtualbox.org/

@Raum1807 How's cm11? What features have been implemented so far?

Of course, because you didn't hit the thanks button. (joking, but of course, just press it now)

Your problem is with folder permissions. I don't know how you created the folders but somehow you just don't have enough permisions now.

Try to:
chmod a+x /home/bruce/bin/repo

sjoerd0301 · Nov 6, 2013 at 8:29 PM

Bah my linux box broke.. @op Can you release the cm11 build you made?

It's work in progress... :fingers-crossed:

It's actually very nice. A bit rough around the corners at the moment... But since KitKat is just a few days old, the progress right now is already fantastic compared to last year's Android 4.2-Release. I am looking forward to the days after the M2 release of CM10.2 when most of the devs will focus on CM11.0. Everything is mostly in English, but the handling is very smooth and my short test didn't reveal anything as not working.

Oh, and a printing feature has been implemented (not tested), new launcher is coming (Launcher 3), etc.

Looks very promising!

Remember guys if you try this that you can't use the ART compiler with De-Odexed GApps, so you will have to use PA GApps instead.

looks great. printing is part of 4.4 not CM

can you check if compass is working?

Right! Thanks. Forgot to post it.

The PA-GAPPS (FULL COMPLETE PACKAGE) from yesterday is what I was using with my test-build.

Look for Download-Link under
Full Complete Package ~201MB
then for
pa_gapps-full-4.4-20131105b-signed.zip

Maps was working; GPS signal was fast and precise. But I must admit that I haven't tested the compass function while in maps...

iceolate · Nov 6, 2013 at 8:52 PM

Dang!! Now I can't wait to get out of work and try this. I've never compiled my own ROM before, but I'm looking forward to trying it with your instructions. I have full backups of my phone right now in case I blow it up. Will need to fire up Virtual Box, as one commenter pointed out. Good idea

jukiewalsh · Nov 6, 2013 at 9:09 PM

Could this work with other phones? Assuming we use the correct device specific calls

I said that, then the build I tried from Dev-Host still FC's with the PA GApps you linked and the ART compiler :S

pa gapps are deodexed. you need odex gapps to work with ART. Use this - http://d-h.st/8PP

PA Odexed GApps?
