[Micromax A110] ##W4TCH0UT##:
Hello guys. I have seen a lot of activity here. But I found almost no one knew about source building in this community. Another reason for posting is for people who want to build cm11 from scratch themselves. Our computer crashes most of the time.

Here starts the fun :

Prerequisites

Quote:

1. Ubuntu 13.10 / BBQLINUX (I personally use this)
2. patience...lots and lots of patience.

1. Installing ubuntu 13.10.

Quote:

This can be done in 3 ways and I am not gonna cover it all.

- along with windows ,i.e dual boot

- in virtualbox within windows

- as a windows application installation with "wubi" installer

For starting user i think second option, i.e installing in virtualbox is best.

here's starting tutorials

NOTE - you should have atleast 100 Gb partion for virtualbox.

2. Setting up building environment.

THIS ALL BELOW STEPS ARE NOT NEEDED IF YOU HAVE INSTALLED BBQLINUX, BUILDING ENVIRONMENT IS SET IN BBQLINUX BY DEFAULT. IT WORKS OUT-OF-THE-BOX.

Initializing a fresh Android Build Environment in Ubuntu 13.10 sucks, right? The instructions at the AOSP page are outdated and inaccurate. Near as I can tell, they try to have you install 2 JDKs, the first one not even being the correct link for Saucy Salamander, and the second being OpenJDK. Which might work. But I dunno about all that, I’d rather have Oracle’s official stamp when it comes to building for Android.

Currently most of the guides are up to 12.04 LTS, which is fine and dandy, but being on the cutting edge is nice too.

This guide applies to all variations of Ubuntu 13.10 Saucy Salamander 64 bit. Do not use the 32 Bit version. Also, PAY CLOSE ATTENTION when to use “sudo” and when to not. It can make things funky if you do something as root that you shouldn’t.

Much thanks goes out to Google, ProTekk, Canonical, and everyone else that I read a random paragraph here and snippet there.

First lets perform an update:

sudo apt-get update

After this Restart ubuntu.

Okay, let’s set up the correct JDK.

Many of you probably have some kind of wrong Java installed unless you’re starting with a fresh Ubuntu base, and even then maybe.

Let’s get rid of that. Copy and paste this into a Terminal window:

Code:

sudo apt-get purge openjdk-\* icedtea-\* icedtea6-\*

Follow the instructions to remove OpenJDK.

If you must keep it, it’s possible. But I’m not going to tell you how to do it here. I don’t want any chance of confusion or mistake.

Now copy and paste the following into the Terminal:

Code:

sudo add-apt-repository ppa:webupd8team/java

This will add the correct PPA to your system for updated builds of Java 6 JDK that are compatible with 13.10.

No more unrecognized Java version errors! And it will update automatically with the rest of your system.

Next, we actually need to install the package. More copy-paste:

Code:

sudo apt-get update && sudo apt-get install oracle-java6-installer

Follow the on-screen instructions. You have to Accept the Licensing Agreement to complete the install. Hopefully no human centipede clauses.

Let’s make sure the correct version of Java is activated, run the following Terminal command:

Code:

java -version

You should see something like the following:

Code:

java version “1.6.0_45″ Java(TM) SE Runtime Environment (build 1.6.0_45-b06) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01, mixed mode)

Ok, back to a fresh Terminal prompt. Time for installing the guts to build stuff in Ubuntu:

Code:

sudo apt-get install git-core gnupg ccache lzop flex bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 libc6-dev lib32ncurses5 lib32z1 lib32bz2-1.0 lib32ncurses5-dev x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 lib32z-dev libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc readline-common libreadline6-dev libreadline6 lib32readline-gplv2-dev libncurses5-dev lib32readline5 lib32readline6 libreadline-dev libreadline6-dev:i386 libreadline6:i386 bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev lib32bz2-dev libsdl1.2-dev libesd0-dev squashfs-tools pngcrush schedtool libwxgtk2.8-dev python

When that is done installing, run the following command in your Terminal window:

Code:

sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

That’s it on the package side of things.

You guessed it, time for more Terminal. This really is the easiest way, seriously. And it’s totally worth it when you’re basking in the glory of a bunch of people on XDA.

The binary for a program called “repo” will let you talk to git servers and download all that precious source code. That second part after the && allows it to be executable:

Code:

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

Use your favorite text editor to open ~/.bashrc

I like nano:

Code:

sudo nano ~/.bashrc

At the very bottom, add the following line:

Code:

export PATH=~/bin:$PATH

Save it. In nano that would be Ctrl-O and then Enter. Then Ctrl-X to exit back to a prompt. Restart bash:

Code:

source ~/.bashrc

Set up android sdk

Refer this guide. Go only to sdk section.

3. Downloading source

Open terminal

To initialize your local repository using the your Rom trees, use a command like this:

mkdir cm11
cd cm11

Repositories of famous roms. Choose one:

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

repo init -u git://github.com/AOKP/platform_manifest.git -b kitkat

repo init -u git://github.com/ResurrectionRemix/platform_manifest.git -b kitkat1

Of course you have to make rom specific changes as they are not supported yet. But will be in near FUTURE. I Will highlight rom specific changes in second post.

Create local_manifest.xml in .repo folder.

cd .repo
nano local_manifest.xml

Paste following into the terminal

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="device/micromax/a110" name="Ateekujjawal/android_device_micromax_a110" remote="github" revision="cm-11.0" />
<project path="kernel/micromax/a110" name="Ateekujjawal/android_kernel_micromax_a110" remote="github" revision="cm-11.0" />
</manifest>

Save it. In nano that would be Ctrl-O and then Enter. Then Ctrl-X to exit back to a prompt. Restart bash.

Then to sync up:

repo sync -j#

# is number of jobs you want to give for your downloading source. I use 2.

Download gonna be huge. Approx 12-15 GB.

So its gonna take while depending upon your internet connection.

You may get errors while downloading, like

Sync exited due to fetch errors

Just restart download by

repo sync

Let's extract those vendors.

cd cm11
cd /device/micromax/a110
./extract-files.sh

Starting Building process

. build/envsetup.sh && time brunch a110 -j#

Again # is meant for No. of CPU cores you have.

Building gonna take time, depending upon your computer configuration.

Any errors, post here.

I will try my best to solve problems .

Start building your own CM11...

Any suggestion welcome.
