Advanced users • How to compile a modified driver & update OS

Hello,

I need some help in building a modified RTC driver for my RPi. I have studied what I thought was the relevant section of the documentation, but could not find the details I needed.

Under the topic heading Kernel Headers, it says:

To compile a kernel module, you need the Linux kernel headers. These provide the function and structure definitions required to compile code that interfaces with the kernel.

This is all I could find in the documentation... Did I miss something??

I beleive I have the kernel headers - they were apparently installed by default on my 64-bit 'bookworm' "Lite" distro for the Zero 2W. Can someone provide instructions for compiling the modified driver on my RPi?
