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

[ipsod]

Here are the steps I follow to reproduce the issue:

1. Install Debian 12 and LinuxCNC according to guide here: https://gnipsel.com/linuxcnc/index.html
2. create stepper sim_inch config with wizard (ran on terminal with command linuxcnc)
3. try to launch machine

This is what I expected to happen:

not an error

This is what happened instead:

It worked properly before this:

this is a fresh install

parallel port, but not sure that's applicable for sim

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

So, what is the content of your /usr/lib/linuxcnc/modules/? I lack hal_speaker.so in my /usr/lib/linuxcnc/modules/ directory. Not quite sure why. -- Happy hacking Petter Reinholdtsen

[petterreinholdtsen]

I just noticed this in src/Makefile ifneq ($(BUILD_SYS),uspace) [...] obj-$(CONFIG_HAL_SPEAKER) += hal_speaker.o hal_speaker-objs := hal/drivers/hal_speaker.o $(MATHSTUB) [...] endif I believe the effect is that the hal_speaker component is not built in uspace mode. I do not really know what the component need, perhaps it can not work with the uspace flavor of linuxcnc?
