I encountered the same problem when building a custom kernel. It works
perfectly fine when I'm building it outside of yocto.

First, I want to document the steps I followed.

My yocto version is thud. I followed the Kernel Development Manual and
used the recipe from the skeleton layer as a base and created the
following recipe:


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

LIC_FILES_CHKSUM =
"file://COPYING;md5=bbea815ee2795b2f4230826c0c6b8814"

KCONFIG_MODE = "--alldefconfig"

SRC_URI = "git://git.toradex.com/linux-
toradex.git;protocol=git;nocheckout=1;branch=${SRCBRANCH} \
           file://defconfig \
           file://imx6q-apalis-
ixora.dts;subdir=git/arch/${ARCH}/boot/dts"

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

LINUX_VERSION ?= "5.2"
LINUX_VERSION_EXTENSION_append = "-delisys"

SRCREV="74e785ce1024471e77b6fb9da83ffd60762c8cac"
SRCBRANCH = "toradex_5.2.y"

PV = "5.2.7"

DEPENDS += "lzop-native bc-native"
COMPATIBLE_MACHINE = "(apalis-imx6)"
KARCH = "arm"
KMACHINE = "apalis-imx6"
KBRANCH = "toradex_5.2.y"


When I build the kernel, I get the following error:

I experimented a little with the devshell and the problem seems to be
that the HOSTCC and HOSTCPP variables are not surrounded by quotes. I
couldn't figure out why this is happening. Did you find a solution?
