Hi, Laurent,

     Thanks for your reply.   Yes, you are right. I have changed the codes, so which can work well now.

template<class GT >

Geomview_stream&

operator<<( Geomview_stream &gv, const Structure_quadrangulation_2<GT> & quad)

{

    bool ascii_bak = gv.get_ascii_mode();

    bool raw_bak = gv.set_raw(true);

    show_quad(gv, quad);

    gv.set_raw(raw_bak);

    gv.set_ascii_mode(ascii_bak);

    return gv;

}

Best

That overload of operator<< matches everything for its second argument. That
overrides even the operator<<(Geomview_stream, const char*), and that causes
the error message.
