Device configuration for generic Halium 9 systemimage

This repository is used to build a generic systemimage for Halium-compatible operating systems.

Building

This is a "device tree", and as such it can be built by loosely following the instructions at docs.halium.org; please see that page for a list of build dependencies and more explicative informations on each of the build steps.

Assuming that you have all the build dependencies and the repo tool, you should run the following commands:

# Get all the needed repositories for a Halium-based build
repo init -u https://github.com/Halium/android -b halium-9.0 --depth=1

A copy of this very repository will be created in device/halium/halium_arm64/; if you are interested in trying out a modification or branch, apply your changes in the repo located in that directory before proceeding:

# Get the required repositories for this specific build
./halium/devices/setup halium_arm64

# Apply Halium patches to the Android source tree
hybris-patches/apply-patches.sh --mb

# Setup the build environment
source build/envsetup.sh && breakfast halium_arm64

# Build the system image
make systemimage

# After quite some time, the output will be in
# out/target/product/halium_arm64/system.img

Note: you need python 2.7 to build this; if the python program shipped by your distribution is python version 3, the build will fail. Consider building this project in a virtualenv:

virtualenv --python 2.7 ~/python27  # adjust the path to your prefs
source ~/python27/bin/activate
