[GRASS-dev] v.digit linking error on osx

[Colin Rundel]

I'm attempting to compile a svn snapshot on my macbook and I'm running  
into a roadblock with getting v.digit to compile. I've followed the  
instructions in the wxpython readme and created the symlink to  
_gdi_.so from wxpython but I get the following error:

  This seems to have something to do with how I've compiled wxpython  
on my system, but playing with the obvious build flags for wxpython  
has had no effect ( I've tried both the current stable release and svn).

Just as a philosophical aside, I havent had much time to explore the  
wxpython code yet, but what was the compelling reason for the use of  
the PseudoDC in the first place? Does the C++ driver provide a  
significant speed up or is it something else that I am missing?

Thanks,
