MenuList Auto-Import Linking Error

[Scott Johnson <scottj cs umn edu>]

Hello Everyone. 

I have been using gtkmm for a couple of years now, developing software 
for school districts as well as for thesis research.  I recently opened 
up an old project that used gtkmm-2.2, and converted it to gtkmm-2.4, as 
well as converting the project from Dev-CPP to Code::Blocks.  Everything 
went successfully, even compilation, when I commented out a small block 
of code:

   // add all of the sub menus to the top menu bar
   MenuList items = topBar->items();

If I don't comment this line out, I get the following error:

overviewwindow.o:overviewwindow.cpp:(.text$_ZN3Gtk12Menu_Helpers8MenuListD1Ev[Gtk::Menu_Helpers::MenuList::~MenuList()]+0xb): 
variable 'vtable for Gtk::Menu_Helpers::MenuList' can't be 
auto-imported. Please read the documentation for ld's 
--enable-auto-import for details.

I have gotten this error in the past, when working with WX, and the 
solution amounted to adding a #define in the compiler options of 
Code::Blocks.  After an hour or so of searching, I am unable to find a 
reference to this problem in relation to gtkmm or GTK+.  I am wondering 
if anyone has any insight into what the compiler #define option might be 
to resolve this, or if there is another solution.  All of my dlls and 
include files were installed using a package installer (i.e. I didn't 
build them from source).  I am using Windows XP as my platform. 

Any help would be appreciated. 

Thanks a lot!
