Hi Kevin,
I can see you have a Makefile Error 2 which could mean you are missing the Linux kernel headers required to build the fusion-hat library module. I had a similar issue building the library for Ubuntu 24.04 on a Pi5.
I posted the solution here Cannot compile driver for Fusion-HAT+ on Pi5 running Ubuntu 24.04 with install script
After re-installing the missing Linux headers the install script and module build worked fine.
The install command will install the correct headers for the OS and version you have installed.
let me know if this works!
Mike
