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 evo
cd evo

repo init -u https://github.com/Evolution-X/manifest -b udc

This adds necessary dependencies for the Evolution-X GSI.

git clone https://github.com/ahnet-69/treble_manifest.git -b evo-udc .repo/local_manifests

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

Copy the patches folder to the ROM folder, and run this in the ROM folder:

patches/apply-patches.sh . trebledroid

Repeat the command for personal, ponces in the patches folder in the order. (e.g. personal then ponces) by replacing trebledroid with the folder name.

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

 cd device/phh/treble
 bash generate.sh evo

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

In the ROM folder, run this to start compilation:

source build/envsetup.sh

ccache -M 50G -F 0

lunch treble_arm64_bgN-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.
