1. xiaomi-marble specific forks

Repo is a tool provided by Google that simplifies using Git in the context of the Android source.

1.1 Installing dependencies and Repo

Several packages are needed in order to build

sudo apt install bc bison build-essential ccache curl flex g++-multilib gcc-multilib git git-lfs gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev liblz4-tool libncurses5 libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-gtk3-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc zip zlib1g-dev

Install Repo tool

# Make a directory where Repo will be stored and add it to the path
$ mkdir ~/.bin
$ PATH=~/.bin:$PATH

# Download Repo itself
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo

# Make Repo executable
$ chmod a+x ~/.bin/repo

1.2 Remove these old Repo

This repository contains the manifest file for an Android project. Below are the rm -rf commands to remove specific old paths:

# Remove these old paths since we are now cloning them from the new LineageOS repository

# hardware/qcom-caf/sm8450/audio/agm
rm -rf hardware/qcom-caf/sm8450/audio/agm

# hardware/qcom-caf/sm8450/audio/pal
rm -rf hardware/qcom-caf/sm8450/audio/pal

# hardware/qcom-caf/sm8450/audio/primary-hal
rm -rf hardware/qcom-caf/sm8450/audio/primary-hal

# hardware/qcom-caf/sm8450/display
rm -rf hardware/qcom-caf/sm8450/display

# hardware/qcom-caf/sm8450/media
rm -rf hardware/qcom-caf/sm8450/media

# vendor/qcom/opensource/audio-hal/st-hal-ar
rm -rf vendor/qcom/opensource/audio-hal/st-hal-ar

# vendor/qcom/opensource/agm
rm -rf vendor/qcom/opensource/agm

# vendor/qcom/opensource/pal
rm -rf vendor/qcom/opensource/pal

# hardware/xiaomi
rm -rf hardware/xiaomi

# vendor/qcom/opensource/display
rm -rf vendor/qcom/opensource/display

# vendor/qcom/opensource/commonsys/display
rm -rf vendor/qcom/opensource/commonsys/display

# vendor/qcom/opensource/commonsys-intf/display
rm -rf vendor/qcom/opensource/commonsys-intf/display

1.3 Initializing Repo

# Create a directory for the source files
# You can name this directory however you want, just remember to replace
# WORKSPACE with your directory for the rest of this guide.
# This can be located anywhere (as long as the fs is case-sensitive)
$ mkdir WORKSPACE
$ cd WORKSPACE

# Install Repo in the created directory
$ repo init -u https://github.com/kenway214/manifest_marble.git -b marble-13 --git-lfs

1.4 Downloading the source tree

This is what you will run each time you want to pull in upstream changes. Keep in mind that on your first run, it is expected to take a while as it will download all the required Android source files and their change histories.

# Let Repo take care of all the hard work
#
# The -j# option specifies the number of concurrent download threads to run.
# 8 threads is a good number for most internet connections.
# You may need to adjust this value if you have a particularly slow connection.
$ repo sync --no-tags --no-clone-bundle --current-branch -j8
