in my specific case (qemu-arm-virt) I got the linux kernel config and

didn't worked for me. Think that you do not have control on what
compiler/environment has been used to generate the kernel binary provided
in the tutorials...
My suggestion is you download the latest version of kernel 4.9, import
.config and symbols file of the current kernel, and first compile your own
linux kernel from scratch and in a separe step. Then overwrite the old
kernel image with your custom image and then change the path of the new
kernel sources in the .build file so the modules can compile correctly.
Hope it helps. Don't hesitate to contact me privately so I can try to help
you and so you can document it as I agree this is really required..

I recently spent a lot of time getting the camkes-vm-linux tutorial to
work, because it is the only example I could find of compiling a kernel
module for the linux vm as a part of the camkes build process.
Unfortunately, the kernel module doesn't seem to work. For more
information, see the previous email chain as well as
In lieu of doing things the right way, I believe I could compile a kernel
module for the linux kernel that is provided as part of the camkes build
system. I believe this is how the introspect-app accomplishes its work.
However, I need to have the exact kernel and exact configuration in order
to compile the kernel module correctly.
Can anyone point me to the correct kernel version and configuration, so
that I can target the provided linux kernel for module compilation?
Or if there's a better way to get a kernel module in there, please let me
