No. This was an attempt to fix this: +IMAGE_CLASSES ??= "" +inherit image_types ${IMAGE_CLASSES} which gives the following bitbake error: ERROR: classes/.bbclass is not a BitBake file ERROR: Command execution failed: Exited with 1 when IMAGE_CLASSES is left as "". It's trying to inherit a ".bbclass" file. There is no good alternative because I have to enforce IMAGE_CLASSES is only modified by appending to it. So the only solution is to modifed the local.conf.sample to say
Right I understood that part from before I think. But why can't you have IMAGE_CLASSES ?= "image_types" and then in the local.conf override that with IMAGE_CLASSES = "image_types_uboot" since image_types_uboot inherits image_types.
IMAGE_CLASSES += "image_types_uboot" and leave the other bit as is...
I have to admit I like this a little better with the possible thought of breaking up image_types a little more, keep more used ones in image_types, but move lesser used ones to their on .bbclass
Them IMAGE_CLASSES truly is a list of image_type classes. Sau!
