if u dont have internet connection to make a ROM this guide is for you and you dont need to have download for GB's of file ;)

first im taking carbon ROM for example

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

To create them run:

mkdir -p ~/bin

mkdir -p ~/carbon

2.Install the Repository

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

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

You may need to reboot for these changes to take effect. Now enter the following to initialize the repository:

cd ~/carbon

Repositories:

Before you continue --> run this in the terminal:

repo init -u https://github.com/CarbonDev/android.git -b kk

3.now open carbon folderand press ctrl + H if u see .repo folder u can continue to next

repo sync --> firsy sync for 5mins to load the folder and then stop syncing by closing terminal

4.after that see the manifest.xml with notepad or any suitable one and you can see link for the packages EXAMPLE: android_art search in the cyanogenmod or in which u want to build

5.im sharing link database of packages for building carbon rest u have the job to search and typer in github

package which to be downloaded for carbon ROM is here http://d-h.st/zru

6.after making source proper --> Building the System --->>>Initialize the environment with the envsetup.sh script. Note that replacing "source" with a single dot saves a few characters, and the short form is more commonly used in documentation.

. build/envsetup.sh

lunch

Enter the number of the build you want to start and press enter:

make carbon -j7 = Run Squisher/Run Opticharger

make otapackage -j7 = No Squisher/No Opticharger

optional --> Submitting Patches
