Hi
I want to run the PocketNC config on my BBB, but it outputs (lines looking
important to my eyes are in colors or underlined):
machinekit@beaglebone:~$ machinekit

Machine configuration directory is
'/home/machinekit/machinekit/configs/ARM.BeagleBone.PocketNC'

ERROR: msgd:0 failed to exit on its own; sending SIGTERM
Cleanup done
Machinekit terminated with an error. For simple cases more information
can be found in the following files:
/home/machinekit/linuxcnc_debug.txt
/home/machinekit/linuxcnc_print.txt
For other cases get more meaningfull information by restarting after
export DEBUG=5
*and look at the output of:*
* /var/log/linuxcnc.log*
* dmesg*
When looking for errors, specifically look for libraries that fail to load
by looking for lines with 'insmod failed' as per example below.
*insmod failed, returned -1:*
*do_load_cmd: dlopen: nonexistant-component.so: cannot open shared object
file:*
*No such file or directory*
For getting help, please have a look here:
www.machinekit.io/docs/getting-help/
My system info. is:
Linux beaglebone *4.14.108-ti-r104* #1 SMP *PREEMPT* Tue Apr 9 18:16:29 UTC
2019 armv7l GNU/Linux
As for the *warning in red *In the error above, I browsed the directory,
and found it looks like:
machinekit@beaglebone:/usr/libexec/linuxcnc$ ls
flavor inivar pci_read pci_write rtapi_app_rt-preempt rtapi_msgd
As obvious, *rtapi_app_posix *is missing.
As for the line in yellow, line 237 of my *realtime* file goes:
local cmd=(${rtapi_app} --instance=$MK_INSTANCE $RTAPI_APP_OPTS)
if [ $DEBUG -gt 0 ] ; then
echo "rtapi_app command: ${cmd[@]}" >&2
*"${cmd[@]}"* *|| (*
e=$?; echo "rtapi_app startup failed; aborting" >&2; exit $e)
else
"${cmd[@]}" 2>&1 || (
e=$?; echo "rtapi_app startup failed; aborting" >&2; exit $e)
fi
As for the closing errors, I have no idea what to do.
Opening the file /var/log/linuxcnc.log, pointed out in the error,
*I have already done these to fix previous/this problem:*
- Applied these instructions
<https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays>
to shift from tree overlays to U-boots.
- To overcome a *"permission denied"* error I used to get, a friend of
mine applied a *chmod 755 *command (or something) and the error doesn't
appear anymore apparently.
If you believe any of the steps I have already taken should have fixed my
problem, let me know please; as I might have missed something somewhere, as
someone new to Linux, M.K and BBB.
*It looks like I have ended up in a dead end on my task. Please help me out
with this, I feel like I have already gone the extent to which I could go
as a beginner.*
