Compiling GTK2 Programs

I've decided to take a look at GTK2, but when I tried compiling the example program, I get this error:

In function `main':
/home/punkrockguy318/gtk/main.cpp:7: undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status

My program is copied right from the site, because I got the same error when I wrote it myself.  Here is what I used to compile

g++ `pkg-config --cflags --libs gtk+-2.0` hello.cpp

What's the deal?

and just for fun, here's the program...

#include <gtk/gtk.h>

int main( int   argc,
          char *argv[] )
{
    GtkWidget *window;
    
    gtk_init (&argc, &argv);
    
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_widget_show  (window);
    
    gtk_main ();
    
    return 0;
}

Re: Compiling GTK2 Programs

GTK is written in C, so I guess you need to have something like:

extern "C" {
#include <gtk/gtk.h>
}

Of course you can also just write your program in C instead of C++, or use the C++ GTK wrapper.
