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
