[yocto] Kernel header missing for specific Target

[Gorny Krystian]

I'm using the fido branch. My iointerrupt.bb file looks as follow:


DESCRIPTION = "Simple IO-interrupt driver"
SECTION = "iointerrupt"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
PR = "r0"

SRC_URI = "file://drv_iointerrupt.c"
S = "${WORKDIR}"
do_compile() {
             ${CC} drv_iointerrupt.c -o iointerrupt
}
do_install() {
             install -d ${D}${bindir}
             install -m 0755 iointerrupt ${D}${bindir}
}

Thanks,
Krystian

What Yocto branch are you using ?

atomic.h is placed in the right location by the kernel build, assuming that your driver recipe has the proper dependencies.  Without seeing that recipe, it is hard to say more.
