Question

i install libgtkmm-3.0-dev in ubuntu 12.04 and i try to learn and write program with c++ and gtkmm 3
i go to this link “http://developer.gnome.org/gtkmm-tutorial/unstable/sec-basics-simple-example.html.en” and try to compile simple example program :

#include <gtkmm.h>

int main(int argc, char *argv[])
{
  Glib::RefPtr<Gtk::Application> app =
    Gtk::Application::create(argc, argv,
      "org.gtkmm.examples.base");

  Gtk::ApplicationWindow window;

  return app->run(window);
}

my file name is “basic.cc” and i open terminal and type following command to compile:

g++ basic.cc -o basic `pkg-config gtkmm-3.0 --cflags --libs`

compile completed without any error but when i try to run program with type ./basic in terminal i get following error :

~$ ./simple
./simple: symbol lookup error: ./simple: undefined symbol:_ZN3Gtk11Application6createERiRPPcRKN4Glib7ustringEN3Gio16ApplicationFlagsE
~$ 

how can i solve this problem ?

i can cimpile any gtkmm 2.4 code with this command : ” g++ basic.cc -o basic pkg-config gtkmm-3.0 --cflags --libs ”
and this command : ” g++ basic.cc -o basic pkg-config gtkmm-2.4 --cflags --libs ”

thanks

I think you hit this gtkmm bug, apparently triggered by more recent versions of GTK+, and now fixed:
https://bugzilla.gnome.org/show_bug.cgi?id=681323

I have asked Ubuntu to update their package, but they are usually slow about that if they do it at all:
