I've fixed the compiler strings in kernel-devsrc, so there's no longer a warning on the target. I'll include the change in one of my next pull requests.

That is expected at the moment, since we are cross compiling on the host, but natively building on the target. kernel-devsrc takes steps to ensure that kernel reconfiguration doesn't happen on target (which I assume you aren't seeing), but it doesn't fix that up. In kernel devsrc, I could also fix that compiler string in the captured .config, but we can't change the kernel-build-artifacts .config, as it is used for future cross builds.

Re: [linux-yocto] Can't compile kernel module under kirkstone
Hi Bruce, Thanks, I missed the "make scripts prepare" 8 years has past since I did this the last time. Now I can compile and load the driver but still get the warning. warning: the compiler differs from the one used to build the kernel The kernel was built by: x86_64-poky-linux-gcc (GCC) 11.3.0 You are using: gcc (GCC) 11.3.0 So something is not 100% correct.

A kernel of that vintage wouldn't have checks for the compiler. We'd have to know more about your image, your layers, if kernel-devsrc is installed on target, and if you've done "make scripts prepare" before starting to build the module.
