Acelan’s Life

Just a simple note about what I have did for building my won Android ROM for my Nexus One

get repo utility from below link

http://source.android.com/download/using-repo

Then run
repo init -u git://github.com/cyanogen/android.git -b eclair
repo sync

Create a file buildspec.mk with those contents(for Nexus One)
TARGET_PRODUCT:=cyanogen_passion
TARGET_BUILD_VARIANT:=eng
TARGET_BUILD_TYPE:=release

Run the command to setup you environment
. build/envsetup.sh

To specifically configure the build system for CyanogenMod
lunch cyanogen_passion-eng

Connect you Nexus One with USB and open debug mode to retrieve proprietary library from cell phone
(cd vendor/google/passion;./extract-files.sh)

make -j4
