Ok, Let's build CyanogenMod for the Epic 4G Touch.

This guide is for Debian or Ubuntu based distros. Works fine for Mint as well.

First, we need to setup a local repo for java6 since its no longer in debian or ubuntus repos..

Setting up a Local Java Repo:

	cd ~/
	wget https://github.com/flexiondotorg/oab-java6/raw/0.2.4/oab-java.sh -O oab-java.sh
	chmod +x oab-java.sh
	sudo ./oab-java.sh
 
 
Install the Build Packages using the package manager:

For 32-bit & 64-bit systems: 

	sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev sun-java6-jdk pngcrush schedtool

Also for 64-bit systems:

	sudo apt-get install g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline5-dev gcc-4.3-multilib g++-4.3-multilib



Create the Directories:

You will need to set up some directories in your build environment.

To create them:

    mkdir -p ~/bin 
    mkdir -p ~/android/system 

Install the Repository

Enter the following to download make executable the "repo" binary:

    curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo 
    chmod a+x ~/bin/repo

Now enter the following to initialize the repository:

    cd ~/android/system/ 
	repo init -u https://github.com/chris41g/cyanogenmod_epic4gtouch.git -b ics

*	repo sync -j$  (where $ is the number of download threads you want to use)
	
When that completes (it will take a while, yes everything takes a while) you need to download some pre-builts.

	vendor/cm/get-prebuilts
	
Now we want to apply any device specific patches that haven't merged upstream.. Darchstar has a script to do that.

	e4gttools/apply.sh
	
Now let's specify what we are going to build.. (Don't forget the . at the begining)

	. build/envsetup.sh && breakfast cm_epic4gtouch-userdebug
	
Ready to start building?

	export THREADS=$(expr 1 + $(grep processor /proc/cpuinfo | wc -l))
    export USE_CCACHE=1
    make -j -l$THREADS bacon
    
When that's done (yes.. it takes a while..) you will have some files in out/target/product/epic4gtouch/ :
	cm-9-XXXXXXX-UNOFFICIAL-epic4gtouch.zip (Where XXXXXX is the date) is the flashable build.
	boot.img is the flashable kernel img.
	
Cleanup:

Now you need to cleanup for your next build, this erases all your builds.. so if you haven't copied them out of that folder, now is a good time.

	make clobber
	make installclean
	
Next build:

Next time you get ready for a build, you need to make sure you get any upstream changes..

To do that, just go back to the step I left an asteriks by and continue from there, everytime you want to make a build.

	*	repo sync -j$  (where $ is the number of download threads you want to use)
