HOW-TO BUILD:

This short guide assumes you're on Ubuntu 11.04 or above

Getting the (right) source

First, we need to create directories for the build (system can be whatever you want to name your working directory):

$ mkdir -p ~/bin

$ mkdir -p ~/android/system

Now we'll need repo. Let's download it and make it executable:

$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo

$ chmod a+x ~/bin/repo

Log out and back in so the changes take effect.

Now initialized the repository and pull the source (with my repos attached):

$ cd ~/android/system/

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

$ repo sync

Depending on your connection, this might take awhile.

Getting my LG Esteem 4G LGMS910 repo

$ cd ~/android/system/device/

$ mkdir lge

$ cd lge

$ git clone https://github.com/playfulgod/android_device_lge_ms910.git -b jellybean ms910

Getting my kernel source repo

$ cd ~/android/system/kernel

$ mkdir lge

$ cd lge

$ git clone https://github.com/playfulgod/android_kernel_lge_ms910.git -b jellybean ms910

Extract necessary binaries and proprietary files

We will need to reuse some proprietary files from the stock ROM:

$ cd

$ cd ~/android/system/device/lge/ms910

$ ./extract-files.sh

or if you have a ROM zip handy you can copy it into the device tree and:

$ ./unzip-files.sh yourROM.zip

Building CM10

Once thats done you can start compiling.

Follow the aosp instructions on setting up the build environment. - http://source.android.com/source/download.html

When the environment is setup, we need to grab a copy of Koush's ROM Manager and the Term.apk. This is necessary to build CM10.

$ cd ~/android/system/vendor/cm

$ ./get-prebuilts

Now, we build (system being your work directory):

$ cd ~/android/system

To build for the LG Esteem:

$ . build/envsetup.sh && brunch ms910

Installing CM10

If the build was successful, you can now take the update zip found in out/target/product/ms910/ and flash using a custom recovery. Make sure to grab the latest Gapps to complete the experience.

When you want to rebuild with new changes to the BoardConfig.mk or after syncing to the latest CM src make sure to do the following before you recompile.

$ make clobber
