[GRASS5] nviz problem

Hi,

I noticed today that nviz doesn't work if I run it background as before.
Similarly, it just stops after displaying a map when it's executed from
"d.m &" which is recommended in the welcome message.

nviz elevation=dem & # doesn't work
d.m & # nviz doesn't work

nviz elevation=dem # works!
d.m # nviz works!

And I see nviz prints % prompt. Does anyone have a clue?

Thanks.

It must be the latest change that was done - I just tried it and it
does not work even if I do nviz elevation=dem, it displays the DEM
but fails to open the Main pannel and prints a % prompt.
It worked OK just a few days (weeks?) ago.
It may be related to the change in the startup script - Bob, are you
around? How does it work for you?

Hello,

I tried running the latest version of nviz in the background with various options and it seems to work fine. The "%" prompt that you see is perfectly normal. The nviz program is simply a customized version of the Tcl/Tk "wish" executable. Try executing "wish" on the command line and you should see the same prompt.

As for it crashing when it is run in the background, I have no idea. You might try changing GRASS_MESSAGE_FORMAT environment variable to see if that has any effect.

It might help to know what platform and Tcl/Tk version it is failing on.

For me it works on RedHat 7.3 with Tk8.3, and RedHat 9 with Tk8.4.

Hi,

Now nviz is not a *wish script but a shell itself. That's why it prints
a prompt and we cannot execute it background and inside "d.m &". To fix
this problem, I think we should go back to NVWISH because running nviz
foreground is pain.

You can test this:

  wish &

prints % prompt and just stop!
