Package: kernel-package
Version: 12.036+nmu3
Tags: patch
I am rather new to the arm architecture and currently trying to
get a couple of things working on a Raspberry Pi. Building
kernel packages natively on a 700MHz single-core ARMv6 cpu takes
ages, so I have been looking into possibilities for
cross-building kernel packages from faster architectures.
According to the make-kpkg manpage, the following command
$ make-kpkg --arch armhf --cross_compile arm-rpi-linux-gnueabi- \
--revision 20131002 --append_to_version -rpi --initrd \
--us --uc --rootcmd fakeroot kernel_image
should build an armhf kernel package on an amd64 host with an
arm-rpi-linux-gnueabi-crosstoolchain installed. With
kernel-package 12.036+nmu3 this fails with
debian/ruleset/misc/checks.mk:36: *** Error. I do not know
where the kernel image goes to [kimagedest undefined] The usual
case for this is that I could not determine which arch or
subarch this machine belongs to. Please specify a subarch, and
try again.. Stop.
It looks like there are just a few definitions for armhf missing,
which are only used in the case of cross-building - native builds
work fine. With the attached patch, cross-building kernel
packages for armhf works for me, i.e. it results in working
kernel-image packages for the Raspberry Pi. I had asked on
debian-arm whether anybody sees issues with the patch, but have
received no reply.
Regards,
Karsten
