Installing LinuxCNC 2.8 on Debian 11

may want to add a -j switch for your dpkg-buildpackage for your number of processors as it will spreed up the build time

in my case -j4

ymmv

Hi, I'm jean-yves from France,
I compiled LinuxCNC 2.9  and packaged following the RJ11 and robertsparc recommandations.
Added the -j6 since my cpu is a 6 parts amd : it was fast.
But before going futher  my questions are now :
1/ Would i have to compile into a realtime kernel?
2/ And may i hope a compiled kernel available and recommended for this ?
Thank's very much in advance.

Here my current kernel:
Linux DebianMsrv64 5.16.0-8.2-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 5.16-7.1~bullseye (2022-02-09) x86_64 GNU/Linux
SMP PREEMPT but not RT.
For now i just need to drive a CH341 machine (Arduino), it's a common 2D + laser light laser. I'll afford soon a drilling machine.
It is pluged on /dev/ttyUSB0
Thank You.

normally, you would just install the PREEMP_RT kernel with something like

sudo apt-get install linux-image-rt-$(uname -r)

But because you are running a non standard kernel, this won't work. So yes, you need to compile the patched prempt_rt kernel or revert to a debian kernel.
