Installing LinuxCNC 2.8.4 on Raspbian 10 (Buster) tested on Raspberry Pi 3B+, Pi

Also the first part of this line is a link? Ah you need to add code tags...

-d /usr/lib/linux-image-$KERN/broadcom && cp -d /usr/lib/linux-image-$KERN/broadcom/* /boot/$KERN/

Have you guys tried these?

If you go bookworm, preempt_rt is packaged and so is linuxcnc.
This is a headless install and leaves you with root access only  no pw
so to get a graphical environment you can (no sudo cos you are root)
apt install tasksel
tasksel
select a graphical environment
xfce?
reboot.
Its been a while since i've done this. I know at one stage vtk was missing and I compiled it but I suspect its been added.
There is a good video on youtube with a lady that goes through it step by step on bullseye (not the preempt_rt stuff)

Looks like the forum changed your commands because you didn't use code tags

I think this is the correct command.

tasksel seems to do nothing and is already installed... you do have to login as root

I followed this a couple of years ago and it worked

And what Seb said in the mail list back in september:
This is awesome!

I tried the "2022-08-08" Bookworm image for Raspberry Pi 4.  The image
is for the arm64 architecture.  Everything seems to work fine on a
Raspberry Pi 4B, including wifi, GUI, and the serial console.

After `apt-get install linuxcnc-uspace linux-image-rt-arm64` and a
little bit of tweaking, I'm now getting latencies around 150 µs, which
is not as good as the Raspbian Buster armhf image at  linuxcnc.org  (~70
µs latency) but probably acceptable.

It's neat that there are several easy(-ish), usable options for LinuxCNC
on Raspberry Pi now.
