RPI4 Raspbian 64 bit & LinuxCNC

are you sure you did the

sudo apt update

before
sudo apt full-upgrade

Do you really need deb packages?

Why not just build and run LinuxCNC in-place?

Alternatively, does anyone have a working .deb package that we can just put on the repository?

one of these ought to work:

pkgs.org/download/libgl-dev

Yes many times in that order.

@ Aciera how do I install them from your link?
I am sorry I in a bit over my head.
This is what I tried

sudo apt-get install /https://debian.pkgs.org/sid/debian-main-amd64/libgl-dev_1.3.2-
1_amd64.deb

@ andypaugh
I can try that but I am not sure how you build it in place is there a procedure for building in place? I do not think I have seen one but I have read about people doing it but that is the extent in my knowledge
I have also read about quick and easy install in Mint is that a better choice for OS them Raspbian 64 bit? any opinions?

cd linuxcnc-dev
cd src
./autogen.sh
./configure
make
(wait)
sudo make setuid

You now (should) have a working LinuxCNC system in the linuxcnc-dev folder. To set the system to run that.

. ../scripts/rip-environment
linuxcnc

(That really is dot space dot dot slash space, and assumes that you are still in linuxcnc-dev/src. The general form is . {path to scripts}/rip-environment. dot-space is a command line shortcut for "run this script" and dot dot slash (the rest) is the path to the rip script.)

That did not get me all the way there
I get stuck at "make" step.
this is the response.
make
Makefile:99: *** Makefile.inc must specify RTPREFIX and other variables. Stop.
pi@raspberrypi:~/linuxcnc-dev/src $

Try from ./configure onwards but with "./configure --with-realtime=uspace"
