continuing my trek through coding pedantry and was wondering about
the exact purpose of the common line in .bbappend files:
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
or some slight variation thereof.
i *thought* i knew what it did, so i did a small experiment with the
meta-ti layer and netbase (since i was already messing around with
it), and i replaced the contents of the netbase .bbappend file with
the single line:
FILESEXTRAPATHS_prepend := "rday"
and checked the environment for the value of FILESPATH for the netbase
recipe and, after formatting to read it clearly, what i saw was:
FILESPATH="rday/linux-gnueabi
rday/arm
rday/build-linux
rday/pn-netbase
rday/beagleboard
rday/omap3
rday/armv7a
rday/
rday/class-target
rday/forcevariable
rday/libc-glibc
rday/

/home/rpjday/OE/dist/layers/oe-core/meta/recipes-core/netbase/netbase-5.0/omap3
... snip ...
what the heck? if that's what FILESEXTRAPATHS is supposed to do,
that is definitely *not* how it's being used in many, many bbappend
files.
is there an explanation somewhere as to what the above is supposed
to represent?

What is puzzling about the above? Its doing what it was designed to do.
The idea is to add the directory listed to the set of directories that
get "autogenerated" from OVERRIDES as search locations. What did you
expect it to do?
FWIW there is no need to use := with FILESEXTRAPATHS, or prepend for
that matter, just use +=/=+.
Cheers,
Richard

i am, right this minute, looking at the explanation of
FILESEXTRAPATHS in the poky reference manual glossary. i see
absolutely no mention of the word "OVERRIDES".
signing off for the evening as i'm starting to get annoyed ...

It sounds like the docs are missing some details about how this works
and what its designed to do. We should add the information and there are
several of us who will happily work with Scott on fixing that.
Getting annoyed isn't going to help.
I'd also add that we're about to change the way this works a little so
we'd perhaps better hold off fixing the manual until we've made that
change (which will simplify the lists of search paths you've been seeing
further).
Scott: Looks like we need to tweak the manual in this location. Could
you open a bug or otherwise track this please?
Cheers,
Richard

i'm in the midst of writing a wiki page on this for my upcoming
class, so once i'm done, feel free to steal.
and on a related note, my profuse apologies for my snottiness
earlier -- i was totally missing the critical point about bbappend
files being stacked which made all the difference and cleared
everything up.
grrrrrrr ... my bad.

have i written anything abysmally stupid here so far?
http://www.crashcourse.ca/wiki/index.php/FILESEXTRAPATHS_and_bbappend_files
i really like to use live examples from the source to explain my
points.
a bit more coming for that page ...
