 I don't manage for a while to compile wx-vdigit on Mandriva 2009.0:

 Digging around I found this comment:

 "I went and told it specifically to enable the graphics context during
 configure. Seems to be working now"

 http://thread.gmane.org/gmane.comp.lib.wxwidgets.general/56401/focus=56446

 (whatever that means)

 Also found comments here:
 http://lists.wxwidgets.org/pipermail/wx-dev/2007-November/094820.html

 "If I use wxGCDC, I get the following error:
   error: ‘wxGCDC’ was not declared in this scope;
 even if I include <wx/dcgraph.h>.

 I think, I have to configure wxWidgets with an additional  --enable-
 graphics_ctx - flag."

 Looking for the definition, I find:

 {{{
 grep wxGCDC /usr/include/wx-2.8/wx*/*
 /usr/include/wx-2.8/wx/dcgraph.h:#define wxGCDC wxDC
 /usr/include/wx-2.8/wx/dcgraph.h:class WXDLLEXPORT wxGCDC:
 /usr/include/wx-2.8/wx/dcgraph.h:    DECLARE_DYNAMIC_CLASS(wxGCDC)
 /usr/include/wx-2.8/wx/dcgraph.h:    DECLARE_NO_COPY_CLASS(wxGCDC)
 /usr/include/wx-2.8/wx/dcgraph.h:    wxGCDC(const wxWindowDC& dc);
 /usr/include/wx-2.8/wx/dcgraph.h:    wxGCDC( const wxMemoryDC& dc);
 /usr/include/wx-2.8/wx/dcgraph.h:    wxGCDC();
 /usr/include/wx-2.8/wx/dcgraph.h:    virtual ~wxGCDC();
 }}}

 Not sure what's missing here. Maybe missing

 #include <wx/dcgraph.h>

 ?
