[linux-yocto] Problems building meta-skeleton

[Mats Liljegren]

I try to build my home-brewed kernel using the linux-yocto-custom.bb as
template. I've named my file "linux-omap4_3.9.bb" since this is what the
machine specification for PandaBoard requires.

The error I get is:

--------------------

ERROR: Error executing a python function in

--------------------

My file looks like this:

--------------------

inherit kernel
require recipes-kernel/linux/linux-yocto.inc

COMPATIBLE_MACHINE = "omap4"

SRC_URI = "file://defconfig "

S = "${TOPDIR}/../kernel-linus"

KERNEL_EXTRA_ARGS = "LOADADDR=0x80008000"

LINUX_VERSION = "3.9"
LINUX_VERSION_EXTENSION = "-custom"

PR = "r1"
PV = "${LINUX_VERSION}"

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"

--------------------

I notice that meta/classes/archiver.bbclass has the code mentioned in the
error messages above, and it seems like it will fail anytime S does not
contain linux-yocto.

Why is this conditional there? Does it try to protect itself from something?
Right now it seems to me like it is causing an uninitialized variable error,
but maybe I'm doing something wrong here...
