c - gtkmozembed 段错误

Question

我无法让 gtkmozembed 工作:

#include <gtk/gtk.h>
#include <gdk/gdk.h>
#include <gtkmozembed.h>
#include <stdlib.h>
#include <stdio.h>
static void destroy( GtkWidget *widget,
                     gpointer   data )
{   
    gtk_main_quit ();
}

int main( int   argc,
          char *argv[] )
{   
    GtkWidget *window, *mozwidget;

    gtk_init (&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    g_signal_connect (window, "destroy",
                      G_CALLBACK (destroy), NULL);

    mozwidget=gtk_moz_embed_new();

    gtk_moz_embed_load_url (GTK_MOZ_EMBED(mozwidget),"http://www.google.com");

    gtk_container_add (GTK_CONTAINER (window), mozwidget);

       //last line running correctly
    gtk_widget_show_all(window);
       //not running anything after this line

    gtk_window_set_skip_taskbar_hint(GTK_WINDOW(window),TRUE);
    gtk_window_set_type_hint(GTK_WINDOW(window),GDK_WINDOW_TYPE_HINT_DOCK),
    gtk_window_set_skip_pager_hint(GTK_WINDOW(window),TRUE);
    gtk_window_set_keep_below(GTK_WINDOW(window),TRUE);
    gtk_window_set_decorated(GTK_WINDOW(window),FALSE);
    gtk_window_stick(GTK_WINDOW(window));

    gtk_main ();

    return 0;
}

我编译使用:

gcc -g main.c -o xulwidget $(pkg-config --cflags --libs gtk+-2.0) -I /usr/include/xulrunner-2.0 -L /usr/lib/xulrunner-2.0 -lxul

错误:第 30 行左右的段错误(请参阅上面的注释)

自 4.0 起，Mozilla 不再可嵌入。

不要尝试，使用 GtkWebkit，如果您在 Windows/MacOSX 上需要它，请踢维护人员的屁股，让他们不应该如此依赖单一平台。
