[GRASS-user] [pid file issue for d.* ]

GRASS GRASS user

This is what command shell throws:

Cleaning up temporary files…
Starting GRASS GIS…
WARNING: Concurrent mapset locking is not supported on Windows
Executing <d.mon wx2> …
Execution of <d.mon wx2> finished.
Cleaning up temporary files…

C:\Users\WRPPF-A>ERROR: Variable ‘LOCATION_NAME’ not set
Traceback (most recent call last):
File “C:\Program Files\GRASS GIS 7.2.0/gui/wxpython/mapdisp/main.py”, line 608, in
fd = open(pidFile, ‘w’)
IOError: [Errno 2] No such file or directory: ‘C:\Users\WRPPF-A\Documents\grassdata\nc_spm_08_grass7\user1\.tmp/unknown/MONITORS/wx2\pid’

What am I missing?

I have attached my script herewith this mail.

I see a mixture of \\ and / path separators:

In this section

there are hardcoded / which might be wrong (/me guessing).

Thanks for attention, Markus
The problem seems to be with the path, however, I am quite lost here. I have not been able to figure out that which part of my script has to be edited.

This means that GRASS GIS session ended and d.mon wx0 is trying to run in
the background, see #3252 for explanation:
