I am attempting to build wxPython under Cyqwin. Like the message posted on the listserv September 14, I am getting an error message for a missing CreateBitmap member in the class wxGraphicsRenderer. The complete output from build step 9 showing all of the error messages follows at the end of this message. I made the modifications to both the setup.h file and the timer.cpp files as indicated in the build instructions and the _gdi_wrap.cpp file as suggested in the previous e-mail. The output below indicates that I still am seeing the same problem even with the updated files. I have included snips from both setup.h and _gdi_wrap.cpp with the modifications in the event that I either entered the information incorrectly or that there is another problem in the file that I have missed. The widgets installed fine and run the test cases without a problem, so I would appreciate any suggestions as to where to go from here to complete the wxPython build.

Thanks,

virtual wxGraphicsBrush CreateRadialGradientBrush( wxDouble xo, wxDouble yo, wxDouble xc, wxDouble yc, wxDouble radius, const wxColour &oColor, const wxColour &cColor) { return wxNullGraphicsBrush; }

virtual wxGraphicsFont CreateFont( const wxFont &, const wxColour & ) { return wxNullGraphicsFont; }

/* Next line added per per web message regarding installation: CAS - 11/27/2009 */ virtual wxGraphicsBitmap CreateBitmap ( const wxBitmap & ) { return wxNullGraphicsBitmap; }

This line was added in the wrong place; it should be added at about line 4156. The instructions at http://gnuradio.org/trac/wiki/wxPythonCygwin include a patch that does this for you.

wxGraphicsBitmap CreateBitmap( const wxBitmap &bitmap ) const { return wxNullGraphicsBitmap; }
