[yocto] eo_filter_out not working

[Johan Thelin]

Hi,

I'm trying to build the packagegroup-core-p1 from the meta-ivi layer,
but I would like to remove the RRECOMMENDS as I don't want X11. To do
this, I've added a packagegroup-core-p1.bbappend to my own layer. In
this file I've tried the following options:

Attempt #1

RRECOMMENDS_packagegroup-core-p1 :=
"${@oe_filter_out('packagegroup-xserver-ivi',
'${RRECOMMENDS_packagegroup-core-p1}', d)}"

ERROR: ExpansionError during parsing
/home/e8johan/work/yocto/pelagicore-bsp/sources/meta-ivi/recipes-yocto-ivi/packagegroups/packagegroup-core-p1.bb:
Failure expanding variable RRECOMMENDS_packagegroup-core-p1[:=],
expression was ${@oe_filter_out('packagegroup-xserver-ivi',
'${RRECOMMENDS_packagegroup-core-p1}', d)} which triggered exception
SyntaxError: EOL while scanning string literal
(RRECOMMENDS_packagegroup-core-p1[:=], line 1)


I read this as RECOMMENDS_packagegroup-core-p1 is not yet set, so the
oe_filter_out part fails.



Attempt #2

RRECOMMENDS_packagegroup-core-p1 := "foo"

WARNING: Variable key RRECOMMENDS_${PN} (    packagegroup-xserver-ivi
   ) replaces original key RRECOMMENDS_packagegroup-core-p1 (foo).


This sort of explains why attempt #1 fails, as it seems that the bb is
evaluated after the bbappend.



So this leads me to my question. Why is the bb apparently evaluated
after the bbappend? Running bitbake with -DDD does not indicate this
(see below), so I smell something fishy (or I don't fully grasp how
things are meant to work)

$ bitbake -DDD packagegroup-core-p1 | grep core-p1

So, what am I doing wrong?
