OsX IDE, 6011dev4. When compiling our application that works with 602 and 605 on NetBSD and Windows, I am getting a new problem of which I am uncertain as to how to fix.

Misc.h:

class RowDisplay : public Display{
        Color fore;
        Color back;
public:
  void SetColors(Color f, Color b);
  void Paint(Draw& w, const Rect& r, const Value& value,Color ink, Color paper, 
dword s) const;
  void PaintBackground(Draw& w, const Rect& r, const Value& value,Color ink, Col
or paper, dword s) const;
};

Misc.cpp

  void RowDisplay::Paint(Draw& w, const Rect& r, const Value& value,
             Color ink, Color paper, dword s) const
  {
    Display::Paint(w, r, value, fore, back, s);
  }
  void RowDisplay::PaintBackground(Draw& w, const Rect& r, const Value& value,
             Color ink, Color paper, dword s) const
  {
    Display::PaintBackground(w, r, value, fore, back, s);
  }

Will result in:

/usr/bin/ld: Undefined symbols:
Display::Paint(Draw&, Rect_<int> const&, Value const&, Color, Color, unsigned int) const

Note that the identical code calling PaintBackground works just fine. This is the only error, if I comment out Display::Paint line, it links and runs. But hard to use as it does not paint the lines correctly.

Draw/Display.h

        virtual void PaintBackground(Draw& w, const Rect& r, const Value& q,
                                     Color ink, Color paper, dword style) const;
        virtual void Paint(Draw& w, const Rect& r, const Value& q,
                               Color ink, Color paper, dword style) const = 0;

Draw/Display.h defines both the same, except ::Paint has "= 0" at the end. (But no difference if I take that out).

Any clues?

Is the Rect_<int> causing the issue?
