[gnomemm] More Help Needed

[Dan Pixley <danpixley cox net>]

Hi all.  Another newb question for you here.  I am just learning Gtkmm
and glade--, and am having problems getting my test program to link. 
compiling with "g++ main.cc -o gnumu `pkg-config gtkmm-2.0
libglademm-2.0 --cflags --libs`", I get three errors saying:

 "/tmp/ccrs09HB.o(.text+0x35): In function `main': : undefined reference
to `gnumu::gnumu[in-charge]()'"   

The other two errors are similar and complain about "gnumu::~gnumu
[in-charge]()".  Here are my files:

GnuMu.h:

 #ifndef GNUMU_H
#define GNUMU_U
 
#include <gtkmm.h>
#include <libglademm.h>
 
class gnumu : public Gtk::Window
{
public:
   gnumu ();
   virtual ~gnumu ();
 
protected:
   //  Connect to a new world.
   //  Test: outputs "Connecting World1" to
   virtual void on_connect_activate ();
   //  When the enter key is pressed in the text inputbox.
   //  Test: outputs entered text to output textbox
   virtual void on_input_entry_key_release_event ();
   //  When button is pressed, world is activated in textbox.
   virtual void on_button1_clicked ();
    
   //  MenuBar.
   Gtk::MenuBar menu_Bar;
   Gtk::Menu menu_File, menu_Edit;
   Gtk::Menu menu_Connect, menu_Quit; //submenus.
   //  Buttons.  Only first two buttons implemented for testing.
   Gtk::Button button1;
   Gtk::Button button2;
   //  Output and input textboxs.
   Gtk::TextView* output_textview;
   Gtk::Entry* input_entry;
    
   Glib::RefPtr<Gnome::Glade::Xml> xml_interface;

   set_resizable (true);

Note that you cannot compile this without the .glade file.  I am also
aware that there are probably lots of other bugs in this code, but I am
stuck on this first one, and need some help working through it.  Also, I
prefer to use the g++ command instead of autoconf and automake just so I
get a feel for that compiler (and I need to learn autoconf and automake
as well.  One thing at a time though.).  I'm new to lots of this stuff.
:)  If anyone can spot my linking error, please let me know.  

Thanks in advance,
Dan
