Building

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

Create 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 ~/evo
cd ~/evo

Initalize the Treble Evolution X repo

repo init --depth=1 -u https://github.com/Evolution-X/manifest -b udc

Clone the Manifest

This adds necessary dependencies for the Evolution X GSI.

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

Sync the repository

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

Apply the patches

Run this command in the ROM folder:

./patches/apply-patches.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_evo_patches repo.

Warning

Superuser removal patch might not get applied using this script, despite being applyable. While this is being investigated, please apply it manually. cd ~/evo/build/make && git am ~/evo/patches/0002-personal/platform_build/000*-remove-su-from-builds.patch

Adapting for Evolution X

Run the following commands:

cd ~/evo/device/phh/treble
bash generate.sh ~/evo/device/mytja/evo/evo.mk

This will generate all appropriate treble configurations.

Turn On Caching

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

Build Treble app

This GSI uses a modified Treble app in order to achieve more functionality. You need to build the Treble app.

cd ~/evo/treble_app

./build.sh release

Compilation

In the ROM folder (~/evo), run this to start compilation:

source build/envsetup.sh

ccache -M 50G -F 0

lunch treble_arm64_bgN-userdebug 

make systemimage -j$(nproc --all)

Compression

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 

Troubleshooting

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