How To Build

Step 1: Setting up the Build Environment.

You'll need Linux to be able to build Cyanogenmod. You have three choices here; you can:

1. Install Linux natively on your computer.
2. Dual boot Linux and Windows.
3. Use virtual machine software ( virtual box, vmware ) to run linux.

NOTE: I recommend you use Ubuntu 14.04 LTS to build. That's what I use.

Now read this: http://source.android.com/source/initializing.html

NOTE: When I say "read", I mean read and comprehend.

In addition to Android's build prerequisites CyanogenMod requires "maven"

sudo apt-get install maven2

NOTE: Read through the topics here as well: http://wiki.cyanogenmod.org/w/Development

Step 2: Downloading the Source.

NOTE: Some say that it is better to download the ROM source and put in your local manifest later. I don't know if that's best but that's what we are going to do.

BEFORE YOU BEGIN: You are about to start downloading 5 - 15 Gigs of data. That could take a very long time, so plan accordingly. I like to start just before I go to sleep and let it go overnight! If you have to work, perhaps start it before work and let it go through out the day.

Execute the following commands in a linux terminal:

mkdir /home/$USER/cm
cd /home/$USER/cm
repo init -u git://github.com/CyanogenMod/android.git -b cm-13.0
repo sync

WARNING: There may be times, towards the end when it seem like, the download is stuck and not making any progress because there are no updates on the screen. BE PATIENT!, open a program that will show how much bandwidth you are using to be sure!

Step 3: Set up local manifest.

The local manifest is different for every device. It contains those repos that are device specific, where as the ROM code you just "repo sync'd" is code that is general to any device.

NOTE: Meticulus Development also builds some extra features and functions into its builds and we include the source for those builds in this tree as well. If you would like to include those "extras", then when asked to issue the "./patch.sh" command, include the keyword "meticulus" after it e.g. "./patch.sh meticulus". We respectfully ask that you do not publish or distribute these builds.

Execute the following commands in a linux terminal:

mkdir /home/$USER/cm/.repo/local_manifests
gedit /home/$USER/cm/.repo/local_manifests/hi6250.xml

Copy the following into hi6250.xml, save and close.

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
  <project name="Meticulus/android_kernel_huawei_hi6250" path="kernel/huawei/hi6250" remote="github" revision="master"/>
  <project name="Meticulus/android_device_huawei_hi6250" path="device/huawei/hi6250" remote="github" revision="master"/>
  <project name="Meticulus/android_vendor_huawei_hi6250" path="vendor/huawei/hi6250" remote="github" revision="master"/>
  <remove-project name="platform/packages/apps/Nfc"/>
  <project name="CyanogenMod/android_vendor_nxp-nfc_opensource_Nfc" path="vendor/nxp-nfc/opensource/Nfc" remote="github" revision="cm-13.0"/>
  <project name="CyanogenMod/android_vendor_nxp-nfc_opensource_libnfc-nci" path="vendor/nxp-nfc/opensource/libnfc-nci" remote="github" revision="cm-13.0"/>
  <project name="CyanogenMod/android_vendor_nxp-nfc_opensource_frameworks" path="vendor/nxp-nfc/opensource/frameworks" remote="github" revision="cm-13.0"/>
</manifest>

Alternatively, if you would like to include Meticulus Development's "extras" then copy the following into hi6250.xml, save and close.

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
  <project name="Meticulus/android_kernel_huawei_hi6250" path="kernel/huawei/hi6250" remote="github" revision="master"/>
  <project name="Meticulus/android_device_huawei_hi6250" path="device/huawei/hi6250" remote="github" revision="master"/>
  <project name="Meticulus/android_vendor_huawei_hi6250" path="vendor/huawei/hi6250" remote="github" revision="master"/>
  <remove-project name="platform/packages/apps/Nfc"/>
  <project name="CyanogenMod/android_vendor_nxp-nfc_opensource_Nfc" path="vendor/nxp-nfc/opensource/Nfc" remote="github" revision="cm-13.0"/>
  <project name="CyanogenMod/android_vendor_nxp-nfc_opensource_libnfc-nci" path="vendor/nxp-nfc/opensource/libnfc-nci" remote="github" revision="cm-13.0"/>
  <project name="CyanogenMod/android_vendor_nxp-nfc_opensource_frameworks" path="vendor/nxp-nfc/opensource/frameworks" remote="github" revision="cm-13.0"/>
  <project name="Meticulus/android_packages_CodinalteParts" path="packages/apps/CodinalteParts" remote="github" revision="hi6250"/>
  <project name="omnirom/android_packages_PerformanceControl" path="packages/apps/PerformanceControl" remote="github" revision="android-4.4"/>
</manifest>

Execute the following commands in a linux terminal:

cd /home/$USER/cm
repo sync

NOTE: Yes we are syncing again and No, it shouldn't take quite as long. Every time you repo sync just new data is downloaded. So we are downloading the 4 repo's we just put in and any updates that may have occured to the repo's we already have.

Step 4: Building

Now you will want to apply the repo patches. These patches modify code in the ROM to work with this device. Execute the following commands in a linux terminal:

cd /home/$USER/cm/device/huawei/hi6250/patches
./patch.sh

NOTE: If you are going to be offline while you are building, you will need download some prebuilts first.

cd /home/$USER/cm
make fetchprebuilts

NOTE: Now you have everything that you need to build CyanogenMod for your Huawei P9 Lite. Build times depend on you PC performance specifications. In the following terminal command "-j8" represents the number of concurrent tasks to execute. For low specs machines (such as mine) lowering the value to "-j3" may help speed things up. For high spec'd machines raising the value may speed things up.

NOTE: It may take anywhere from 5 hours to 15 hours depending on system specs for a complete build. Execute the following commands in a linux terminal:

cd /home/$USER/cm
. build/envsetup.sh
lunch cm_hi6250-userdebug
make -j8 bacon

Build TWRP ( optional )

NOTE: Currently TWRP can only be built after a successful build of CyanogenMod 13.

Step 1: Setup build env for TWRP

Clone OMNI's recovery (TWRP) into the build system.

cd /home/$USER/cm
git clone https://github.com/omnirom/android_bootable_recovery.git -b android-6.0 bootable/recovery-twrp

Open the BoardConfig.mk file and remove the comment "#" before the line "RECOVERY_VARIANT := twrp". Save BoardConfig.mk

Re-run patch.sh to patch bootable/recovery-twrp

cd /home/$USER/cm/device/huawei/hi6250/patches
./patch.sh

Step 2: Build TWRP

cd /home/$USER/cm
. build/envsetup.sh
lunch cm_hi6250-userdebug
make -j8 recoveryimage

NOTE: remember to re-add the "#" before "RECOVERY_VARIANT := twrp" in the BoardConfig.mk before doing a clean build or it will fail to build!
