To get started with building RisingOS GSI,

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

Create the directories

As a first step, you'll have to create and enter a folder with the appropriate name. To do that, run these commands:

mkdir RisingOS
cd RisingOS

To initialize your local repository, run this command:

repo init --no-repo-verify -u https://github.com/RisingTechOSS/android -b thirteen --git-lfs -g default,-mips,-darwin,-notdefault

Clone the Manifest to add necessary dependencies for gsi:

git clone https://github.com/MisterZtr/treble_manifest.git .repo/local_manifests  -b 13

Afterwards, sync the source by running this command:

repo sync --force-sync --optimized-fetch --no-tags --no-clone-bundle --prune -j$(nproc --all)

After syncing, apply the patches:

Copy the patches folder to rom folder and in rom folder

bash patches/apply-patches.sh .

Generating Rom Makefile

Clone this repository and then copy pixel.mk to device/phh/treble in rom folder. Then run the following commands:,

cd device/phh/treble

For vanilla version,

bash generate.sh RisingOS

For gapps version,

bash generate.sh RisingOS+GApps

Turn on caching to speed up build

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

Compilation

In rom folder,

. build/envsetup.sh
ccache -M 50G -F 0
lunch treble_arm64_bvN-userdebug 
make systemimage -j$(nproc --all)

Compress

After compilation, If you want to compress the build. In rom folder,

cd out/target/product/tdgsi_arm64_ab
xz -z -k system.img

Troubleshoot

If you face any conflicts while applying patches, apply the patch manually.
