Well, found that.  (I went back to the 2.4 release, by the way).

Immediately was informed that
    wxhello.cc:26: error: base class `wxFrame' has incomplete type
So I #included <wx/frame.h>

The was informed that 
    g++ -I/usr/lib/wx/include/base-2.4/ wxhello.cc -o wxhello
    In file included from /usr/include/wx/window.h:27,
                     from /usr/include/wx/toplevel.h:25,
                     from /usr/include/wx/frame.h:23,
                     from wxhello.cc:18:
    /usr/include/wx/cursor.h: In constructor `
       wxBusyCursorSuspender::wxBusyCursorSuspender()':
    /usr/include/wx/cursor.h:46: error: `wxIsBusy' undeclared (first use this
       function)
    /usr/include/wx/cursor.h:46: error: (Each undeclared identifier is reported
       only once for each function it appears in.)

I did not find wxIsBusy by grepping the the obvious places.

Am I still doing something wrong?

The compile comand, from Makefile
	g++ -I/usr/lib/wx/include/base-2.4/ wxhello.cc -o wxhello

And my source code, actually cut & pasted from a tutorial.

I sould have thought of that.  Thanks.
