I tried to send this email previously to gtkmm-list, but then it could not be delivered. Trying again now.

It's quite strange. I can run the book/menus/main_menu example. You obviously have a new enough version of glibmm's header files, or else the compilation would have failed. Is it possible that your library file libgiomm-2.4.so* is older than your header files (such as giomm/actionmap.h)? Improbable, but it's the only explanation I can think of now.

Hi Mr. Kjell,

2013/10/24 Kjell Ahlstedt <kjell ahlstedt bredband net>

Gio::ActionMap::add_action(const Glib::ustring& name, const ActivateSlot& slot)
was added in glibmm 2.37.5 and modified in 2.37.6.
Is it possible that you had access to a newer version of glibmm when you compiled the program, and then an older version when you ran the program?

$ pkg-config --modversion glibmm-2.4
2.38.0

So, yes !... I'm using a newer version of glibmm, but in this case and after the deprecations of Gtk::Action, Gtk::ActionGroup...

Which is the preferred method to design menus ?

Is there an example code available somewhere ?

Hi guys,

Taking this example code:
https://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/menus/main_menu

(compiled with Gtkmm-3.10.0 as follows: $ g++ examplewindow.cc main.cc -o menu `pkg-config --cflags --libs gtkmm-3.0`)

Is it normal that it breaks with an error message like,
./menu: symbol lookup error: ./menu: undefined symbol: _ZN3Gio9ActionMap10add_actionERKN4Glib7ustringERKN4sigc4slotIvNS5_3nilES7_S7_S7_S7_S7_S7_EE

at runtime ?

Is it something wrong ?
