Kernel headers (source) for 5.10.46

[bluuu81]

If we want to add any module to kernel we need latest headers and source.
For example for dkms and cm4io-fan ... I can't build module
Any advices are welcome

Yeah, thanks
Now module is building ... but can't work because of modprobe: ERROR: could not insert 'emc2301': Exec format error (with and without --force)
Don't know is a module or headers issue :/

What is your module make command line? And the output of uname -a?

[bluuu81]

Makefile (so make too is from cm4io-fan: https://github.com/neg2led/cm4io-fan):
https://github.com/neg2led/cm4io-fan/blob/master/Makefile

uname -a:
Linux greennas 5.10.46-v8+ #1430 SMP PREEMPT Mon Jun 28 17:17:17 BST 2021 aarch64 GNU/Linux

That Makefile doesn't make it obvious what the actual kernel make line would be. For example, does it include ARCH=aarch64?
I suspect your problem might be that you are trying to build a 64-bit kernel with a native 32-bit gcc. What does file vmlinux return after the build?
