Re: [Machinekit] pru_generic.so: cannot open shared object file: No such file or directory

Charles was right, I was missing the name :) This now loads the pru: loadrt hal_pru_generic prucode=/usr/lib/linuxcnc/rt-preempt/pru_generic.bin pru=0 halname=hpg Thank you all for your help and fast response Regards Klemen On Fri, 12 May 2023 at 21:47, John Allwine wrote: > Maybe symlinking

Maybe symlinking the other file would work? sudo ln -s /usr/lib/linuxcnc/rt-preempt/hal_pru_generic.so /usr/lib/linuxcnc/rt-preempt/pru_generic.so Also, maybe specify the specific file for your prucode, which includes the .bin? loadrt prucode=/usr/lib/linuxcnc/rt-preempt/pru_generic.bin pru=0

Re: [Machinekit] pru_generic.so: cannot open shared object file: No such file or directory

You are missing the name of the HAL driver. The loadrt command expects a driver name, then the arguments. The error in your first command shows the HAL system trying to load the HAL driver named: "prucode=/usr/lib/linuxcnc/rt-preempt/hal_pru_generic" ...you need something like: loadrt

Yes, it looks like that library is ok. I don't know how up-to-date these paths/filenames are but have you tried looking in the various places described here: https://github.com/machinekit/machinekit/blob/master/scripts/linuxcnc.in#L210 Machinekit terminated with an error. For simple cases

Try running this command to see if a dependent library is missing: $ ldd /usr/lib/linuxcnc/rt-preempt/hal_pru_generic.so On Friday, May 12, 2023 at 12:06:20 PM UTC-6 fogl wrote: > Thank you for your reply, > > I tried both options, but with no luck: > 1. loadrt

Thank you for your reply, I tried both options, but with no luck: 1. loadrt prucode=/usr/lib/linuxcnc/rt-preempt/hal_pru_generic pru=0 halname=hpg returns msgd:0 stopped rtapi:0 stopped rtapi_msgd command: /usr/libexec/linuxcnc/rtapi_msgd --instance=0 --rtmsglevel=1 --usrmsglevel=1 --debug=1

Re: [Machinekit] pru_generic.so: cannot open shared object file: No such file or directory

Your output indicates dlopen is looking for "pru_generic.so" but your filesystem only has "hal_pru_generic.so". You need to fix the script(s) trying to load the PRU HAL module or make a symlink or something so the file dlopen is looking for actually exists. On 5/12/2023 9:38 AM, fogl wrote:

Is it just a matter of adding the .bin to the file name? Something like this: loadrt prucode=/usr/lib/linuxcnc/rt-preempt/pru_generic.bin pru=0 halname=hpg On Fri, May 12, 2023 at 8:38 AM fogl wrote: > Hello everybody, > > I am stuck with machinekit and pru. I am running a single line .hal

Hello everybody, I am stuck with machinekit and pru. I am running a single line .hal file: loadrt prucode=/usr/lib/linuxcnc/rt-preempt/pru_generic pru=0 halname=hpg This returns: msgd:0 stopped rtapi:0 stopped rtapi_msgd command: /usr/libexec/linuxcnc/rtapi_msgd --instance=0 --rtmsglevel=1
