GTK初学者疑问求教

按着Peter Wright的GTK+/GNOME程序设计这本书上输入程序，
第四章的windowposition这个例程，编译没问题，但是生成的程序不能
正常运行，产生了大量的Gtk-WARNING和Gtk-CRITICAL。但是按着
书输入的前两章的程序编译运行都没有问题，笨人是初学者，刚入门，一
时不知从何着手，还请前辈高人指点一二。
笨人的系统是FreeBSD 7.2R。
源程序如下：
#include <gtk12/gtk/gtk.h>

void CloseTheApp(GtkWidget *Window,gpointer data)
{
gtk_main_quit();
}

void BuildAWindow(const gchar *title,GtkWindowPosition position)
{
GtkWidget *window;
window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_position(GTK_WINDOW(window),position);
gtk_window_set_default_size(GTK_WINDOW(window),320,200);
gtk_window_set_title(GTK_WINDOW(window),title);
gtk_signal_connect(GTK_OBJECT(window),"destroy",GTK_SIGNAL_FUNC(CloseTheApp),NULL);
gtk_widget_show(window);
}

gint main(gint argc,gchar *argv[])
{
BuildAWindow("Normal",GTK_WIN_POS_NONE);
BuildAWindow("Center",GTK_WIN_POS_CENTER);
BuildAWindow("Mouse",GTK_WIN_POS_MOUSE);
gtk_main();
return 0;
}

产生的错误如下：
