Re: Keep .bbappend for older Yocto version


Jonas Vautherin
 

Thank you for the answer :-). Yes, that works, and it seems like it is commonly used already. But because there is a way to define which versions are supported in the machine configuration, I thought there may be a way without branches, i.e. having a layer that actually is compatible with multiple versions.

Otherwise what's the point of LAYERSERIES_COMPAT, if the way to move to another version is to branch away? Is that a legacy option?

Best,

perhaps you should create a new branch for this layer which will be
compatible with gatesgarth, you can seed it with dunfell branch

In my case, I want to define `linux-yocto_5.4.bbappend` for Gatesgarth. When building with Dunfell, I would like it to use the former, and when building with Gatesgarth, I would like it to use the latter.
