Hi all
I am trying to get a custom kernel recipe to work and it fails by
issuing a weird make command - the command contains the arguments
one
would pass to gcc when cross-compiling. Bitbake spits a NOTE about

----------------------
We have a device with a vortex86 (mainly i586 or i686 without CMOV)
processor why I created a corresponding machine. The machine is
defined
with tune-i586.inc. The machine definition seems to be fine, the
cross
compiler gets built and many packages build correctly for the
target
system. This is the machine configuration:
----------------------
require conf/machine/include/tune-i586.inc
TARGET_ARCH = "i586"
PREFERRED_PROVIDER_virtual/kernel = "linux-vortex86"
MACHINE_FEATURES = "ext2 irda keyboard pcbios pci rtc screen serial
touchscreen usbhost"
TARGET_FPU ?= "soft"
X86ARCH32 ?= "i586"
TUNE_PKGARCH = "${TUNE_PKGARCH_tune-${DEFAULTTUNE}}"
TUNECONFLICTS[m32] = "m64 mx32"
TUNE_ARCH = "i586"
GLIBC_ADDONS = "nptl"
SERIAL_CONSOLES = "115200;ttymxc2"
IMAGE_FSTYPES += "wic wic.bmap"
WKS_FILE ?= "kraemer.wks"
do_image_wic[depends] += "gptfdisk-native:do_populate_sysroot"
do_image_wic[recrdeptask] += "do_bootimg"
----------------------
I guess the problem lies in the kernel recipe, since everything
else
seems to be fine. I started with a recipe that was shown on the
presentation "Working with the Linux Kernel in the Yocto Project"
that
was published in March this year:
https://www.youtube.com/watch?v=tZACGS5nQxw
This didn't work though and I started to search the documentation.
I
finally found:
https://www.yoctoproject.org/docs/1.6.1/kernel-dev/kernel-dev.html#
working-with-your-own-sources
So I went ahead and modified until I got the current version of the
recipe:
----------------------
SECTION = "kernel"
DESCRIPTION = "Linux kernel for the Vortex86 processor"
LICENSE = "GPLv2"
FILESEXTRAPATHS_prepend = "${THISDIR}/linux-vortex86:"
LIC_FILES_CHKSUM =
"file://COPYING;md5=d7810fab7487fb0aad327b76f1be7cd7"
require recipes-kernel/linux/linux-yocto.inc
inherit kernel
SRCBRANCH = "linux-4.14.y"
SRCREV = "80a4edf7eba019147d93e60843bd2dda66526d5c"
SRC_URI =
"git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git;bra
nch=${SRCBRANCH} \
file://defconfig \
file://bootlogo.ppm"
LINUX_VERSION ?= "4.14.65"
S = "${WORKDIR}/git"
PV = "4.14.65"
PR = "r0"
COMPATIBLE_MACHINE = "vortex86"
----------------------
Does anybody know what is wrong with that recipe? Why does bitbake
for
building the kernel call make with arguments for gcc?
Those are the flags for HOSTCC/HOSTCPP not for the actual building of
the kernel image, they are required to properly build host components
of the kernel (i.e. mconf) against the sysroot.
The error that you are pasting looks more like an invalid type of
image (zImage) for your configured machine.
Bruce
Thanks for any hints!
Best Regards
Dave

The problem is that the flags _are_ used in order to build the kernel -
make finally complains about unknown arguments - that's what it
complains about - I realize I haven't included the concrete output of
the make call (cut lots of output at the end):
I assure you, they aren't. The kernel build system does not take
flags from the outside, it defines it own. But maybe we are talking
about different things. I'm talking about the kernel's host native
binaries.
That is HOSTCC in your dump below.
The CC and LD look ok at a glance,
If HOSTCC is not properly running on your build machine, then yes,
it has a bad set of flags. But that is buried in the machine configs,
not the kernel recipes or kernel build.
make -j 8 HOSTCC=gcc

How come all these options (-isystem etc. etc.) are passed to the make
call to build the kernel? This is wrong - these are not make options,
instead, it should contain ARCH=a CROSS_COMPILE=b etc. but not the
arguments used - the ones really necessary are not present at all.
It isn't wrong. If you look in the git history of oe-core, you'll see
all the reasons for these changes. They were about getting the native
binaries properly built.
Bruce
Can anyone tell me what is wrong with my recipe? Is this not the
recommended way to go? If not, how should I include a kernel for a
machine that linux-yocto does not initially support?
Thanks!
Best Regards
Dave
