Try to install LInuxCNC without image

I'm trying to make LinuxCNC working on OrangePi 3b and I'm using Debian12 bookworm(from orange pi official website).
It's a minimal linux with GUI I guess.

Now I'm trying to install RT(RTAI or PREEMP I'm not sure) and LinuxCNC 2.9.2 
I'm try to figure out the best (right) way to do.....

I tried to use apt and dpkg(install deb file), but failed, none of them work...

To install an rt kernel for a SBC you need to patch/compile it yourself in most cases.
This rt-kernel is for the RK3588 (Orange Pi 5), you could give it a try, but there is a chance that it won't boot because of missing drivers:

Here is the source that's already patched (rt)

Linuxcnc 2.9.2
