dbouce.so: cannot open shared object file

Hi,

after loading dbounce in my machine.hal, LinuxCNC exits with the following error message:

dbounce: dlopen: /usr/lib/linuxcnc/modules/dbounce.so: cannot open shared object file: No such file or directory

All other realtime components load fine so far. I checked the path but dbounce.so is present at /usr/lib/linuxcnc/modules/.
The error shows up as soon as I try load the component with
loadrt dbounce names=dbounce_probe

The machine runs fine now for 3 years. LinuxCNC is 2.8 on Debian 9.13.0. My "old" config can be found here but it doesn't include the changes I just tried to make: github.com/hausen8/AL_1105

Any help is appreciated,
Tilman

Well, I could but since I called all components with names, I would like to keep this order. I just had the idea to check owner and rights, assuming that all modules shold have the same owner/group/permissions.

What if I copy dbounce.so from another computer with LCNC 2.8 into this folder? Could this work?

Surely not because debounce will be loaded with filter groups (loadrt debounce cfg=N,N).

But you're right: Instead of wasting time trying to get dbouce working I should rather give debounce a try.
