run

(Based on https://wiki.odroid.com/odroid-n2/software/using_docker)

cd superbird-buildroot/
docker run --name superbird_buildroot -v $PWD:/srv -it odroid/meson64-dev:202106

resume stopped container

docker start -i superbird_buildroot

build

In docker :

. ./setenv.sh mesong12a_u200_32_release

cd buildroot/
make mesong12a_u200_32_release_defconfig
make weston

superbird-buildroot's Issues

Module `multimedia/gst-aml-plugins` is missing

The buildscript fails almost immediately after running setenv.sh:

Add Google Cobalt as git submodule

The setup procedure could be simplified (admittedly, it's just one step to omit) by adding the Cobalt repository as a git submodule. It would also tie the Cobalt version being used to a known working commit, although it would also require manual updates of the gitref every time Cobalt is updated.
