how to apply bbappend selectively

how to apply bbappend selectively

[Jaap de Jong]

Hi All,

I.m creating a special image with for instance a modified udev package.
I've created a udev-xxx.bbappend for that purpose.
But for all the other images I build for other hardware I still want to 
use the original udev-xxx.
There is probably a simple solution but I don't see it...
Any ideas?

Thanks in advance!
Jaap

Usually this is just done with machine overrides within the bbappend.

e.g.

SRC_URI_append_somemachine = "file://somefile.patch"
SOMEVARIABLE_somemachine = "value1"
ANOTHERVARIABLE_somemachine = "value2"

That way building for all other machines will be unaffected.

Cheers,
Paul

Well, PACKAGE_ARCH_somemachine = "${MACHINE_ARCH}" will do that; although if 
you're manipulating SRC_URI then it's supposed to set that automatically.
