bbappend

[Jaap de Jong]

Hi all!

I need some help concerning bbappend.
I've created a bbappend file:

    FILESEXTRAPATHS := "${THISDIR}/files"
    SRC_URI += "file://xyzzy.patch"

If I run a bitbake it complains about missing ..../xyzzy.patch
When I change the bbappend file to this:

    SRC_URI += "file:///absolute-path-to-the-file/files/xyzzy.patch"

then everything works fine...
(As a workaround this will do)

Any help is appreciated!!
Jaap

FILESEXTRAPATHS is only available in oe-core. For classic OE you need to use 
something like:

THISDIR := "${@os.path.dirname(bb.data.getVar('FILE', d, True))}"
FILESPATHBASE_prepend := "${THISDIR}/files:"

Cheers,

Hi Paul,

Thanks for clarifying and proposing a workaround.  It looks like PRINC
is similar, where it is only available in oe-core.  It seems like the
code related to incrementing the PR variable is a several-line fix, so
is this something that can be abstracted into a class file in the
local-overlay?

Thanks again,
Chris

Possibly, however as a general suggestion I would recommend moving things over 
to being based on oe-core if at all possible. I realise this is not going to 
be practical for everyone in the short term, however OE classic will stop 
being maintained at some point in the near future, so the sooner you move the 
better - plus you get to take advantage of the additional features and 
cleanups in oe-core as well.

Cheers,
Paul

I'd love to.  My most recent project is just starting out, so it's a
good time to make the switch.  Are there any good references for
performing a migration?

Thanks,

We're rather lacking in oe-core specific documentation right now; however, you 
should be able to just grab oe-core and get started with it fairly easily:

 https://wiki.yoctoproject.org/wiki/OpenEmbedded-Core

If you have any questions feel free to post them on the oe-core list:

Hi All,

I want to make use of a standard oe package but I don't want it to be 
started at boot time.
Is there a way to disable update-rc.d (INITSCRIPT_*) from within a bbappend?

Thanks!
Jaap
