Daniel,

as discussed, I've experimented with meta-rpb and the Yocto Compatible check scripts.. see : https://www.yoctoproject.org/docs/2.6/mega-manual/mega-manual.html#making-su...

There are many obvious reasons why it's a good idea to make sure that layers can pass this script..

I was able to get meta-rpb to pass the compatibility check with the following patches: https://github.com/ndechesne/meta-rpb/tree/check-layer

The simplest way to run the script is to use a copy of Poky git:

$ git clone http://git.yoctoproject.org/git/poky $ cd poky $ source oe-init-build-env $ yocto-check-layer <oe-rpb folder>/layers/meta-rpb/ --dependency <oe-rpb folder>/layers/

The main things that the script will test are:

1. Adding your layer in bblayers.conf will not change any recipe content/checksum 2. All dependencies are properly tracked

For meta-rpb, we depend on meta-virtualization (docker) and that layer breaks compatibility in many ways.. so I had to remove references to docker and meta-virt to run the script..

I will be doing a bit more testing/review, and submit the PR.

cheers nico
