[yocto] Error during kernel module compilation

[Nicolas Salmin]

Hi all,

I have some trouble during kernel module compilation, in fact the module is
build successfully only if I have built the kernel before... it makes sense
but the the recipe inherit from module bbclass:

/*********************************************************************************************************************
SUMMARY = "USB **** driver"
DESCRIPTION = "Module for USB host device communication"

inherit module

SRC_URI = "git://git@
********************************.git;branch=${branch-driver-*****};protocol=ssh"
SRCREV = "${commit-****-*****}"
PR = "r0"

SRC_URI += "file://Makefile"

PV = "${PVBASE}.${SRCPV}"
PVBASE := "${PV}"
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PVBASE}:"


S = "${WORKDIR}/git"

do_compile_prepend() {
   echo "overriding Makefile"
   cp ${WORKDIR}/Makefile ${S}
}

/*********************************************************************************************************************

It was that was like dependencies are not correctly set...

For information i'm using a custom recipe linux kernel so maybe i have
forgotten to add some variables inside.
Thanks for helping,
Cheers.
Nicolas
