Hi Frank,

I downloaded the latest 6.6-main package and I'm trying to dkms install a module having the following issue. Any idea how to resolve it?

Seems like I can re-generate the content of this folder by running make. However now I'm getting this error. Any idea how to generate the Kconfig file?

I'm not sure what you trying to do...headers are only h files,no full kernel code...these are only for compiling 3rd party apps needing kernel apis (if you try to build a userspace app using gpio or similar).

Kconfig files are source for menuconfig and only in full source and not generable

I'm trying to build jool module via dkms and dkms is throwing an error when it tries to execute the files in the script folder. I belive this is caused due to the binaries being compiled for x86 arquitecture

It is possible that the debs are not all built right, libc,headers and dbg packages are built automaticly with the kbuild system...

You can get information about a file with the command "file",afair it also shows the architecture it was built for

Package name contains the right arch,but maybe not all tools support crosscompilation

Maybe this helps https://stackoverflow.com/questions/73698666/kernel-module-on-cross-compile-kernel-bin-sh-1-scripts-basic-fixdep-exec-fo

I ended up installing debian's official linux-kbuild-6.7.9 for arm64 package and using the scripts in it
