Gmoccapy not starting "out of the box" on Linux (or WSL) #1933

Closed smoe closed 1 year ago

smoe commented 2 years ago

Sidenote: I need to thank @hansu to also check WSL. That cannot be used for anything time-critical because of the latencies (330 µs for base -> 980 while typing this report, 184 µs for servo -> 566) on a 10 yo i7 and Win10, but we should find out where its limits are. The one or other educational value this should well have.

After installation on Debian (regular Linux machine or WSL) the direct execution of /usr/bin/gmoccapy demands first of an environment variable CONFIG_DIR and once that is given, also one for LINUXCNC_TCL_DIR, so I tried

LINUXCNC_TCL_DIR=/usr/lib/tcltk/linuxcnc CONFIG_DIR=/usr/share/gmoccapy gmoccapy

which led to another error:

Traceback (most recent call last):
  File "/usr/bin/gmoccapy", line 5365, in <module>
    app = gmoccapy(sys.argv)
  File "/usr/bin/gmoccapy", line 172, in __init__
    self.stat.poll()
SystemError: <method 'poll' of 'linuxcnc.stat' objects> returned NULL without setting an exception

This is a bit cryptic. Preferably, some default paths would have been chosen and the user would just start the binary.

Well. I should first have executed linuxcnc. But that is what gmoccapy could have told me, too. The gmoccapy screen starts up with the 3 axes mill simulation, but not without a first error box because of

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/gladevcp/iconview.py", line 118, in __init__

that I could click away, but then the later file icon error kills it. A copy of stdout/err is added below.

Oh, I thought was was fixed with https://github.com/LinuxCNC/linuxcnc/pull/1548

smoe commented 2 years ago

Ah. Maybe it is. I was using the Debian package that may just not have been updated. I then suggest I'll have another look when https://github.com/LinuxCNC/linuxcnc/pull/1887 is out.

hansu commented 2 years ago

A version before April 25th?

smoe commented 2 years ago

4th of April is in testing. https://tracker.debian.org/pkg/linuxcnc

SebKuzminsky commented 2 years ago

Yes, as you discovered, LinuxCNC GUIs expect to be started by the linuxcnc launcher script, not by a human "by hand" from the terminal or similar.

Can you check if this problem still exists in the current tip of master, and close the issue if not?

smoe commented 2 years ago

Traveling, will check once I am back. /usr/bin is not the correct location for anything that usr is not meant to execute. Should we move all the GUIs to /usr/lib/linuxcnc/bin?

hansu commented 1 year ago

@smoe have you checked that? I guess you are now back from travelling ;-)

smoe commented 1 year ago

I do not see that error when now starting GMOCCAPY correctly on Linux, did not yet run WSL again - thank you for the ping.
