[yocto] Setting up remote debugging with yocto pyro

[Dr. Matthias Schöpfer]

Hello together,

I am facing the following problem: I want to set up gdb(server) remote
debugging. I basically follow very closely this guide
http://www.yoctoproject.org/docs/2.3.1/dev-manual/dev-manual.html#platdev-gdb-remotedebug

My problem: If I do as written there, my -dbg packages are missing the
sources, hence, in my debugfs /usr/src/debug is empty. After doing some
research, I found (and I think, it should be documented there) that

PACKAGE_DEBUG_SPLIT_STYLE = "debug-file-directory"

must be set. And luckily, now the -dbg packages do have the sources
included (checked with oe-pkgdata-util list-pkg-files). But the build of
the image fails. I attached local.conf and the rather lengthy output if
someone is interested. I build pyro with qemu-x86_64 and
core-image-minimal, so nothing too fancy I would guess.

To sum up, I get lots of File not Founds in the pattern:

/home/mschoepf/i-thinx/yocto/qemu_x86_64/tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/rootfs-orig/usr/lib/debug/.build-id/04/3ec7422665726df42d5fd22b151f876fe119e2

while

/home/mschoepf/i-thinx/yocto/qemu_x86_64/tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/rootfs-orig/usr/lib/debug/.build-id/04/3ec7422665726df42d5fd22b151f876fe119e2.debug
exists.

So, basically, any hint how to get this thing working is appreciated! I
do not even have a clue where this files come from...

Regards,

    Matthias
