[GRASS-user] fix for broken wxGUI on Linux

GRASS GRASS user

Markus,

Can you send me an output of the error so that I can try to see where it is coming from?

We've been unable to get GRASS 6.5 or 7 compiled on our Ubuntu 9.2 machines so I can't test it there.

Thanks
Michael

There were a couple of complains lately that wxGUI on Linux is broken. I
just want to mention that wxGUI works for me again (no warnings, no errors)
after I downgraded swig from 1.3.39 to 1.3.35 on Fedora 10.
Maybe downgrading swig helps on other Linux distros too.

right, currently key point is swig version you are using during
compilation of vdigit or nviz.

(meanwhile updated to Mandriva 2010.0, same problem)

I use the distro versions...

This should be change in the future,
broken vdigit or nviz should not affect the whole wxGUI.

Do you think that this could be implemented? In January I would
like to showcase the new GUI in a couple of occasions but I
cannot start it for some months now.
Don't remember how to debug that, though.

there is none (sigh). The map splash screen comes up, then disappears
and I am back to cmd line.

Removing both vdigit and nviz from the GISBASE/wxGUI subdirectories
"solves" the problem. This indicates that SWIG is causing the problem.
Using swig 1.3.40.

What is the problem?

A bit better here on Fedora 12, also using swig 1.3.40. The wxGUI nviz works, the wxdigitizer crashes. Removed swig 1.3.40, got swig 1.3.29, patched that with the patch provided in the wxPython source code, now everything is working, no errors. One warning at grass startup:
warnings.warn("wxPython/wxWidgets release number mismatch")
because Fedora 12 comes with wxBase and wxGTK 2.8.10 and wxPython 2.8.9, but it works.

Ubuntu 9.10 uses wx packages 2.8.10 throughout together with swig 1.3.36, both wx nviz and wx digitizer work just fine.
