I finally found 5 mins to sit and look at where I'd gotten to with the
LAYERSERIES variable handling. I sent out discussion about this a while
ago but as a reminder:
We have a problem where people expect master branch of meta-X to work
with OE-Core master. If meta-X hasn't been maintained for a long time,
this may give all kinds of weird errors. This creates a large support
burden and means we struggle to spot unmaintained/un-updated layers.
We'd like to fix this.
In answer to this I added LAYERSERIES_CORENAMES to OE-Core and strongly
suggest layers then set:
LAYERSERIES_COMPAT_xxx = "sumo"
in their layer.conf where xxx is the collection name (used elsewhere in
layer.conf) to indicate which versions of OE-Core they're expected to
The code already exists to validate this with a fatal error for
mismatches. What was missing was:
a) to print a warning if LAYERSERIES_COMPAT_xxx is unset. I've a patch
queued for bitbake to add this.
b) add a check to yocto-check-layer and require this to be set for YP
Compatible v2. I've added
to track this.
Yes, its late in the release and the warnings will be annoying but I
think its worth fixing this now so I'm pushing ahead to resolve this.
