To get started with Android/Cygnus, you'll need to get familiar with Repo and Version Control with Git.

BUILD ENVIRONMENT

INITIALISING THE MANIFEST

repo init -u https://github.com/cygnus-next/manifest.git -b staging/caf-11

SYNCING THE SOURCE

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

GAPPS

Usage is highly recommended

WITH_GAPPS := true

COMPILING

source build/envsetup.sh
lunch cygnus_device-userdebug
make cygnus -j$(nproc --all)

Since Cygnus doesn't have pathmaps, you need to have your own HALs. You can take HALs from any ROM provided they build fine and don't have any pathmaps in them. The paths for cloning HALs are as follows:

Audio -> vendor/qcom/opensource/audio-hal/primary-hal

Media -> hardware/qcom/media

Display -> hardware/qcom/display

Of course, many HALs can be found in our devices org, on their respective caf-11-x branches and you can use them if your device has the same chipset, Happy Compiling!
