motion.so not found error ...

I have installed LinuxCNC ver 2.9.7 including linuxcnc-uspace. LinuxCNC seems to be running fine.

I'm trying to learn HAL and coded "loadrt motion" in my playground HAL file.

When I open my playground config in LinuxCNC, I keep getting the error: "motion: dlopen: /usr/lib/linuxcnc/modules/motion.so: cannot open shared object file: No such file or directory"

When I run "dpkg -l | grep linuxcnc", I see: "ii  linuxcnc-uspace  1:2.9.7  amd64 motion controller for CNC machines and robots"

When I view the "/usr/lib/linuxcnc/modules" directory there is a "motmod.so" file but no "motion.so" file.

It is my understanding that motmod.so was part of LinuxCNC v2.8 and older and motion.so is part of LinuxCNC v2.9 and up.

I am a new to and just learning LinuxCNC as I prepare for a manual lathe CNC conversion.

Am I doing something wrong? Is there an issue with my LinuxCNC install?

Thanks!

All the Sims work on 2.97 so I suspect the issue is in your hal file. share it and we can look or compare with one of the Sims.

The name is motmod.so

Thank you, attached is my HAL file.

Thank you @Aviera and @Hakan! I will try that.
