[GRASS-user] wxpython gui: d.vect.thematic raises error

yes, compiling vdigit is quite tricky, it needs to be simplified. The
problematic is usage of wxPython wxPseudoDC class which is not part of
wxWidgets itself. Solution would be to use wxDC instead of wxPseudoDC
in vdigit code. The problem is that in the Python code are used
methods of wxPseudoDC which are not available in wxDC class, e.g.
TraslateId() to move objects. Anyway linking against Python extension
_gdi_.so is not solution, it works on Linux machines, but on Mac
(AFAIU).

Congrats, you are one of the few users who manage compile it;-) Enjoy.

Martin
