Hi dear,
I'm installing linuxcnc from source (2.9 version) on a RPi4.
Software building runs fine, no error at all but I cannot start in simulation mode to make my first tests.
I mean, I run the following on the command line:
Code:
. /home/pi/linuxcnc/scripts/rip-environment
linuxcnc
Then I select any default configuration among qtdragon, qmoccapy, even axis and always get the same in my linuxcnc_debug.txt:
Can not find -sec TRAJ -var TPMOD -num 1
Can not find -sec EMCMOT -var HOMEMOD -num 1
Here is my log:
Code:

I can't figure out what is happening. Whatever example configuration I try, I always get the same error basically. I am absolutely lost.
Any addressing will be appreciated!
Thanks in advance.
PS: I realize LINUXCNC_DIR, TPMOD and HOMEMOD are in blanks but, I don't know if it is ok for a default simulation configuration nor where to set up to try.
