[GRASS-dev] Cannot start wxGUI: NotImplementedError: wxGCDC is not available on this platform

[Markus Neteler]

Hi,

after upgrade to Mandriva 2009.1 (64bit) and recompilation of 6.5
without problems, I cannot start the wxGUI:

No compilation errors...

Starting via
g.gui wxpython
pops up the old map screen and then it closes silently.

It the problem that wxPython <= 2.8.9.2 requires swig <= 1.3.36?
I have
rpm -qil wxgtk2.8-2.8.9-3mdv2009.1

wx-config --version
2.8.9

Any ideas?
