Using the correct "xserver-xf86-config_0.1.bbappend

Using the correct "xserver-xf86-config_0.1.bbappend

Trying to build a systemd-gnome-image raspberrypi under Angstrom, with a 
few extra layers.

This fails on "xserver-xf86-config_0.1.[bb|bbappend]"

The extra layer has BBPRIORITY = 20.
meta-beagleboard has BBPRIORITY = 8
meta-raspberrypi has BBPRIORITY = 6 (later changed to 120)

BBLAYERS are in the order meta-<extra layer> meta-beagleboard 
meta-raspberrypi

It looks like bitbake will select the bbappend in the layer with the 
highest priority,
even if that contains a COMPATIBLE_MACHINE clause, which does not
include the current MACHINE.

/Is there any way to make bitbake select the correct bbappend file 
without modifying the BBPRIORITY? /

--------------------------------------------------------------------------------------------
Looks like the xserver-xf86-config for the raspberry-pi fails on

*SRC_URI_append_raspberrypi = " file://xorg.conf.d/*"**
*
When I change to:

*SRC_URI_append_raspberrypi = " file://xorg.conf.d/10-evdev.conf "*

the raspberry pi version completes.

/Wildcards are not allowed?/

Not really. All bbappends are selected the order or sequence of them
is governed by how the layers line up in BBPATH

This is a question of fundamental bitbake semantics/syntax for SRC_URI
and nothing to do with bbappends. and I dont think wildcards in
SRC_URI are reliable, so better be explicit about them.

Hm, it seemed to work if I increased the BBPRIORITY.

Either method seems to be problematic.

If you build for a certain machine, then you want to define which 
bbappend to use
regardless of BBPATH or BBPRIORITY.

Maybe bitbake needs to know which meta-layer contains the <machine>.conf,
and always select a bbappend in that layer, over bbappends in other layers.

Otherwise you have to edit bblayer.conf every time you want to switch to 
a new machine,
which I think is undesirable.

Yes, since this problem occured at the same time,
I thought that I'd mention it as well.
Basically the any image build for raspberry pi involving X is broken then.

All bbappends for a recipe will be applied, in ascending layer priority order; 
BBPATH doesn't come into it.

thanks for correction a hand-brain coordination problem .. dont expect
accuracy when jetlgged :)
