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?

@ 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.)

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