Building

You'll need to get familiar with Git and Repo as well as How to build a GSI.

Glone base repo

Firstly we need to clone the base repo (this one) which we can do by runnng the following:

git clone --depth=1 https://github.com/cawilliamson/treble_voltage.git
cd treble_voltage/

Initalise the Treble VoltageOS repo

Now we want to fetch the VoltageOS manifest files:

mkdir -p src/
cd src/
repo init -u https://github.com/VoltageOS/manifest.git -b 14 --depth=1 --git-lfs

Copy our manifest

Copy our own manifest which is needed for the GSI portion of the build:

mkdir -p .repo/local_manifests
cp -v ../configs/*.xml .repo/local_manifests/

Sync the repository

Sync ALL necessary sources to build the ROM:

repo sync -c -j$(nproc --all) --force-sync --no-clone-bundle --no-tags

Apply the patches

Copy the patches folder to the ROM folder and copy the apply-patches.sh to the rom folder. and run this in the ROM folder:

../patches/apply.sh . trebledroid
../patches/apply.sh . personal

Build the TrebleApp

In order to build our patched TrebleApp you need to run the following:

. build/envsetup.sh
pushd treble_app/
bash build.sh release
cp -v TrebleApp.apk ../vendor/hardware_overlay/TrebleApp/app.apk
popd

Generate base ROM config

In order to generate the base ROM config run the following commands:

pushd device/phh/treble
cp -v ../../../configs/voltage.mk .
bash generate.sh voltage
popd

Compilation

In the ROM folder, run this for building an arm64 standard build (needed even if you want a vndklite build):

. build/envsetup.sh
lunch treble_arm64_bvN-ap1a-userdebug
make systemimage -j$(nproc --all)

Convert standard build to vndklite build (optional)

Run the following commands if you require a vndklite build:

pushd treble_adapter/
cp -v ../out/target/product/tdgsi_arm64_ab/system.img standard_system_arm64.img
sudo bash-adapter.sh 64 standard_system_arm64.img
sudo mv s.img s_arm64.img
sudo chown $(whoami):$(id | awk -F'[()]' '{ print $2 }') s_arm64.img
popd

Troubleshooting

If you face any conflicts while applying patches, apply the patch manually. For any other issues, report them via the Issues tab.
