Hello All,
Seeking assistance to identify a FLAG that allows the application of a condition-based bbappend file during the image compilation process. Any guidance or insights would be greatly appreciated.
For example If 1 is set in the flag, it will indicate inclusion, while 0 will signify exclusion.
Please anyone help me with an example.
Thanks & Regards
Saswati

Well. bbappends are not conditional, however what you do inside them
could be made conditional using packageconfig or DISTRO_FEATURE checks
or other OVERRIDES values.

You can move your bbappend contents to a .inc file, e.g. 'example.inc'.
Then in the bbappend file, you can conditionally include your .inc file
with something like:
require ${@bb.utils.contains('FLAG', '1', 'example.inc', '', d)}
There are some more tricks in the slides for my talk "Creating Friendly
Layers, 2022 Edition" [1] from the Yocto Project Summit 2022.11.

Thank you Khem and Paul.
I was also trying some different ways. We can keep the append file in the
dynamic-layers directory and will use the BB_DYNAMIC flag , which helped me.
Thanks
