Append to bblayers.conf and local.conf

Append to bblayers.conf and local.conf

[Olsson Rikard (RBSN/ESW1)]

Hello Yocto team,

We are receiving bblayer.conf and local.conf from external supplier which already have layers/configuration added. Now we want to add our own layers/configuration by appending to these files this to avoid manual merge work each time a delivery from external supplier is made.

Question:
How do I append layers/configuration to bblayer.conf and local.conf?

Best regards
Rikard Olsson

look at bitbake-layers tool

bitbake-layers add-layer <your-layer>

might be helpful.

The best answer I can give is these files aren't really meant to be 
distributed. If you have too much specific stuff in these files (particularly 
local.conf) then I would say it's possible your supplier has put things in the 
wrong place.

The way it ought to work is, you add the needed layers to your bblayers.conf, 
then go to your local.conf and set DISTRO and MACHINE and anything you need 
for *local* configuration (e.g. local paths) and that's pretty much it. If you 
have to include a whole bunch of extra lines in local.conf, those lines really 
should be elsewhere (e.g. custom distro config, or the machine .conf file if 
they are specific to the machine.)

Cheers,
Paul

Note that you can use conf/auto.conf and conf/site.conf as well, these
files are parsed at the same time as conf/local.conf, so if you really
cannot change local.conf, you can use the one of the other ones.

Hello Nicolas,

Thanks for your answer. Will these two files conf/auto.conf and conf/site.conf be able to handle changes for bblayers.conf as well?

For example we need to add meta-qt5 but would prefer to append to the layers already there and not add our changes into bblayers.conf to avoid merge work.

Best regards
Rikard Olsson

no.

bblayers.conf is parsed by bitbake directly, and i don't think you can
use another file for it. Khem's suggestion to use "bitbake-layer
add-layer" would let you override bblayers.conf 'dynamically' without
having to archive it..

In case it's not clear, all bitbake-layers add-layer does is provide you with 
an easy way to modify bblayers.conf.
