Error after install linuxcnc-dev

Hi Everyone,

I am working on a new driver for my machine and I got into some problem. Since I install the linuxcnc-dev package, I always get a error when I try to start linuxcnc with the sim axis_mm configuration. The same configuration was running fine before.

I can't still run hal without any trouble but linuxcnc is giving me the following error:

I am running in a virtual machine for my development, soo I dont really care about the timing error.

Just want to add that I just got the error with AXIS

Hi

I have had similar errors in the past running a sim config from one version on another version.
It is hard to see how installing the -dev package could make any difference, none of the files are needed to run.

You show running 2.5.2, is it possible you were on 2.5.1 or lower before and installed the -dev package for 2.5.2 which automatically updated linuxcnc to 2.5.2 as well?

What happens if you run the axis_mm config that is in Sample Configs > sim > axis > axis_mm, instead of the one in you home directory?

If that works, copy it over to your home directory, or do a diff to establish what changed, if your home folder one is modified.

regards
