Dear yocto developers,
with the yocto projects < 1.8 we were able to build our out-of-tree
module without any linking failures, but since the upgrade to 1.8 there
seems to be something wrong with the "Module.symvers".
For our external module we use exactly the same Makefile as you proposed
in hello-mod (but of course with another obj-m argument).
If we then build the module, the do_compile stage prints, what you can
find under [1].
I think the problem refers to a wrong "Module.symvers" which is used by
the MODPOST stage.
I just searched for all "Module.symvers" files in my fido work folder,
after a full build:

In my old (projects < 1.8) workfolder, the "Module.symvers" files, where
distributed as follows:

A small hotfix to solve my problem is just a copy of the
"Module.symvers" from the kernel build into my source folder of the
module, by the following extension in my "ov5647.bb":
# Copy the fiel containing all kernel modules
do_patchappend() {
cp -f
/home/myName/fido/tmp/work/amiro-poky-linux-gnueabi/linux-yocto/3.19.2+gitAUTOINC+9e70b482d3_31b35da6a5-r0/linux-amiro-standard-build/Module.symvers
${S}
}
addtask patchappend after do_configure before do_compile
If I take the "Module.symvers" from
"kernel-build-artifacts/Module.symvers", the linkage fails because all
the symbols are missing which are important for the module.
Do you have any Idea, if this is a bug in the new 1.8 build environment,
or if I am doing something wrong?
Greetings,
Timo

Dear yocto developers,
the following "more generic" workaround worked also, which let's me
assume that the "Module.symvers" in ${S} is somehow broken?
Content of "linux-yocto_3.19.bbappend":
do_install_append() {
cp -f ${KBUILD_OUTPUT}/Module.symvers ${STAGING_KERNEL_BUILDDIR}
}
Greetings,
Timo

We have a race condition in the build artifacts copy routine in fido.
The fix missed the release, but we are working through the change now
(the latest variant was posted today).
So yes, what is being copied during the build may not be the proper
.symvers file at the moment, but once do_shared_workdir() is called
directly from the kernel do_install() routine, we'll have the proper
copy in place before your out of tree module builds.
