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.

If so, that is something we test nightly, and as part of the release builds, so it is known to work for all releases (i.e. we won't release with it broken). > > But I actual believe that I use the same compiler as the one used to build > the kernel. > I suspect that the version format from the gcc compiler has changed so the > compare of the versions don't work. > > The kernel compiling works for an old Yocto kernel 3.19.5 from 2015 with > same makefile and source file. 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.
