I have now installed the machinekit and machinekit-posix packages on
an armv7 server
and run machinekit via a normal user account.
I cannot change the kernel to a rt-preempt one, but that should not
matter as all the modules are the same.
It works fine as per the screen grab attached
To help you further:
You will need to remove the existing packages and re-install the new
packages,
empty the /var/log/linuxcnc.log (`> /var/log/linuxcnc.log` as
root, sudo often does not work)
`export DEBUG=5`
then run machinekit and select the sim.tklinuxcnc config
If it errors, the specific fault should be in the log, so attach
that in its entirety.

Using
sudo apt-get install machinekit-rt-preempt
Installation went OK.
But when trying to run machinekit, there is error of
realtime is not running.
Unfortunately the errors do not tell me anything, you will get
those whatever the problem is
I have installed and run the new packages on amd64 Stretch without
any problem
(see attached screen grab)
Unless you can run with DEBUG=5 exported and send me the resulting
/var/log/linuxcnc.log I am going to have
to try and find an arm machine with non root user access to test
them.
Hopefully the tklinuxcnc sim you were trying to run was the stock
one from configs, so I can test like for like?
