[gtkmm] help, I can't compile libgtkmm2.0 programs

[=?x-gbk?q?=D4=F8=CA=B1=D0=C2?= <shixinzeng sjtu edu cn>]

wo copy the code from the tutorial 
http://www.gtkmm.org/gtkmm2/docs/tutorial/html/ch03.html :
#include <gtkmm.h>

int main(int argc, char *argv[])
{
    Gtk::Main kit(argc, argv);

    Gtk::Window window;

    Gtk::Main::run(window);

    return 0;
}
and i compiled it with command:
g++ simple.cc -o simple `pkg-config gtkmm-2.0 --cflags --libs`

It gave me the following error information:
In file included from 
/usr/include/gtkmm-2.0/glibmm/containerhandle_shared.h:34,

I've compiled some other programs wrriten with libgtkmm2.0, and the same 
error occurred. What should I do?

Thanks
