overwrite LAYERSERIES_COMPAT_ for different layer


TRO
 

Hi,
have an issue with a layer which doesn't have the current dunfell release in it's LAYERSERIES_COMPAT_
-> can I overwrite it somehow in a different layer or local.conf?
-> can I configure the error "...is not compatible with the core layer..." to a warning?
cheers, Thomas

You can add a layer which will set LAYERSERIES_COMPAT for another layer, but it needs to be parsed before the layer you want to change, e.g.:
it's useful to use this layer also to implement whatever modifications are needed to make the layer to be actually compatible with the release you're using, like:

FWIW, you could make the parsing order not matter (at least in thud,
from a quick look, master as well). LAYERSERIES_COMPAT is resolved after
all layer.conf have been parsed[1]. I do not know if it's on purpose or
not, meaning it could well disappear in the near future.

So you could override it from anywhere by using __append but it has to
be done before or during the conf/layer.conf parsing. This also makes it
future proof wrt layer priorities and how LAYERSERIES_COMPAT is set (+=,
=, ?= ?).

I personally have it in conf/bblayers.conf (for some reason we "ship"
this one, though it's not best practice IIRC).

Hi,
thanks for the reply - I've put it in the bblayers.conf - working.
cheers, Thomas

Also not recommended, you can put this in your conf/bblayers.conf:

OVERRIDES = "iamgroot"
LAYERSERIES_COMPAT_browser-layer_iamgroot = "zeus"
