You'll need to get familiar with Git and Repo, as well as How to build a GSI.
As a first step, you'll have to create and enter a folder with the appropriate name. To do that, run these commands:
mkdir ~/pixelos
cd ~/pixelos
repo init --depth=1 -u https://github.com/PixelOS-AOSP/manifest.git -b fifteen --git-lfs
This adds necessary dependencies for the PixelOS GSI.
git clone https://github.com/mytja/treble_manifest.git -b pixelos-fifteen .repo/local_manifests
repo sync -c --force-sync --no-clone-bundle --no-tags -j$(nproc --all)
Run this command in the ROM folder:
./patches/apply-all.sh .
This command will apply all TrebleDroid and personal patches. If any patch fails to apply correctly, as indicated by ### FAILED APPLYING
output, you need to apply the patch manually. Steps to do so are described in short on treble_pixelos_patches repo.
You can speed up subsequent builds by adding these lines to your ~/.bashrc
OR ~/.zshrc
file:
export USE_CCACHE=1
export CCACHE_COMPRESS=1
export CCACHE_MAXSIZE=50G # 50 GB
This GSI uses a modified Treble app in order to achieve more functionality. You need to build the Treble app.
cd ~/pixelos/treble_app
./build.sh release
In the ROM folder (~/pixelos
), run this to start compilation:
source build/envsetup.sh
ccache -M 50G -F 0
lunch pixelos_arm64_bgN_erofs-bp1a-userdebug
make systemimage -j$(nproc --all)
After compiling the GSI, you can run this to reduce the system.img
file size:
Warning
You will need to decompress the output file to flash the system.img
. In other words, you cannot flash this file directly.
cd out/target/product/tdgsi_arm64_ab
xz -9 -T0 -v -z system.img
If you face any conflicts while applying patches, apply the patch manually. For any other issues, report them via the Issues tab.
