Note, the SDK required for a specific command will be expressed as follows:

  • HOST: [HOST]

  • PLATFORM_SDK: [PLATFORM]

  • HABUILD_SDK: [HABUILD]

First Time Setup

cd
curl -O https://raw.githubusercontent.com/sailfish-oneplus6/sf-enchilada/master/files/.hadk.env
curl -O https://raw.githubusercontent.com/sailfish-oneplus6/sf-enchilada/master/files/.mersdk.profile
curl -O https://raw.githubusercontent.com/sailfish-oneplus6/sf-enchilada/master/files/.mersdkubu.profile
  • Modify your .bashrc to contain the following:
export PATH=$HOME/bin:$PATH
export PLATFORM_SDK_ROOT="/srv/mer"
export ANDROID_ROOT="$HOME/Sailfish/src"
alias sfossdk="$PLATFORM_SDK_ROOT/sdks/sfossdk/mer-sdk-chroot"

Download and install repo

[HOST]

mkdir ~/bin
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod +x ~/bin/repo

Now follow the OnePlus 5 initial building guide from setup the platform sdk, it's safe to ignore all OnePlus 5 specific information. NOTE: where it says habuild you can use the alias ubu instead.

Thanks @deathmist ;)

From source to device

First time

Setup source tree

[HOST]

cd $ANDROID_ROOT
repo init -u git:https://github.com/mer-hybris/android.git -b hybris-16.0 --depth 1
git clone https://github.com/sailfish-oneplus6/local_manifests .repo/local_manifests

Sync all the required packages

[HABUILD]

repo sync -c -j`nproc` --fetch-submodules --no-clone-bundle --no-tags
# Hybris-16.0 specific patches, not in the HADK yet
hybris-patches/apply-patches.sh --mb
git clone --recurse-submodules https://github.com/mer-hybris/libhybris hybris/mw/libhybris

[HABUILD]

. build/envsetup.sh
breakfast $DEVICE
mka hybris-hal

[HABUILD]

echo "MINIMEDIA_AUDIOPOLICYSERVICE_ENABLE := 1" > external/droidmedia/env.mk
sed "s/Werror/Werror -Wno-unused-parameter/" -i frameworks/av/services/camera/libcameraservice/Android.mk
mka droidmedia audioflingerglue

[PLATFORM]

bp

Every build

Build android parts (boot image + device parts)

[HABUILD]

mka hybris-hal

Copy the fstab to out so that mount units for /system and /vendor get generated properly

cp device/oneplus/sdm845-common/rootdir/etc/fstab.qcom out/target/product/*/root/

Build Sailfish packages and generate a rootfs

[PLATFORM]

bp

If you get an error like No tags describe HEAD, will not fix package version when building rpm/

[PLATFORM]

sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R zypper in droid-config-$DEVICE

Tips

When/what to build a new image

Configs

If only modifying sparse files it is safe to only run:

bp -cvi

This builds droid-configs-$DEVICE, droid-version-$DEVICE and then generates a new image.

Android (HAL) parts

If modifying fstab or any .rc files, run

bp -dvi

This builds droid-hal-$DEVICE, droid-version-$DEVICE and then generates a new image.

Most of the time, you don't need to rebuild everything.
