I am trying to run helloworld (&others) from the gtk+-1.0.4 tutorial.

I also have gtk-0.99.970925-3 and gtk-devel-0.99.970925-3 installed on this
machine under /usr and gtk+-1.0.4 under /usr/local

gtk-config is using:

-L/usr/local/lib -L/usr/X11R6/lib -lgtk -lgdk -lglib -lXext -lX11 -lm
-I/usr/local/lib/glib/include -I/usr/local/include -I/usr/X11R6/include

am I somehow using some of the 0.99 library stuff with the 1.0.4?


here is some of the code and  what gdb tells me.

int main (int argc, char *argv[])
{
    /* GtkWidget is the storage type for widgets */
    GtkWidget *window;
    GtkWidget *button;

    /* this is called in all GTK applications.  arguments are parsed from
     * the command line and are returned to the application. */
    gtk_init (&argc, &argv);

    /* create a new window */
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

    /* when the window is given the "delete_event" signal (this is given
     * by the window manager (usually the 'close' option, or on the
     * titlebar), we ask it to call the delete_event () function
     * as defined above.  The data passed to the callback
     * function is NULL and is ignored in the callback. */
    gtk_signal_connect (GTK_OBJECT (window), "delete_event",
<== stops here
                        GTK_SIGNAL_FUNC (delete_event), NULL);


gdb output:

file hello_world
(xxgdb) run

Program received signal SIGSEGV, Segmentation fault.
0x8048890 in main (argc=1, argv=0xbffffd14) at helloworld.c:54
