LineageOS 17.1 for Sony Xperia devices lilac/xz1c, pioneer/xa2, xz2c, and perhaps more to come.

How to build LineageOS

Initial setup

• Follow the steps for pioneer or really any other device until you get to Initialize the LineageOS source repository:

https://wiki.lineageos.org/devices/pioneer/build/

• Make a workspace:

  mkdir -p ~/android/lineage
  cd ~/android/lineage

• Initialize the repo:

  repo init -u https://github.com/LineageOS/android.git -b lineage-17.1 --git-lfs

• Create local manifests, e.g. by checking out a copy of this project and moving the files to the LineageOS folder:

  git clone https://github.com/Eclipse-Community/build_lineage.git
  mv build_lineage/local_manifests/ .repo/

  If you want to save some space, you can remove files for devices you're not interested in building. Open .repo/local_manifests/roomservice.xml and remove the repos from the manifest. They're all in groups of three, kernel, common, and device. Remove the three or six that don't match what you're building.

• Sync the repo:

  repo sync

• Tell git about Change-Id trailers

  git config --global --get-regexp 'trailer\.' | grep -qF 'Change-Id' || git config --global trailer.changeid.key "Change-Id"

Build procedure

• For XZ1 Compact (lilac) Only

Copy dumped firmware blobs into place for the build

• (Semi-)optionally apply patches

  Compiling without patches is untested. It will probably work if you want a more stock build. However you will need to comment out 'TARGET_KERNEL_CLANG_VERSION := r416183b1' in /device/sony/$platform-common/BoardConfigCommon.mk or BoardConfigPlatform.mk if you go without --minclang.

  To apply all patches (recommended):

  build_lineage/patches/applyPatches.sh

  To apply only the minimal (required & security fix) patches:

  build_lineage/patches/applyPatches.sh --minimal

  To apply only the minimal & new Clang patches:

  build_lineage/patches/applyPatches.sh --minclang

• Setup the environment

  $device is the device you want to build with. For now lilac, pioneer, and xz2c.

  source build/envsetup.sh
  lunch lineage_$device-userdebug

  You may also want to use 'lunch lineage_$device-user' instead if you use certain banking apps and such.

• (Optional) Build with MicroG apps

  !!Requires all patches!! or the signature spoofing patch

  export WITH_GMS=true

• Build LineageOS

  m bacon

When completed, the built files will be in the out/target/product/$device directory.
