Re: "Cannot finding signal handler" even after compiling with -rdynamic

Yes, I had something like that and ended with this which I hope may help you. I was thinking pull the widgets out of the glade file if that makes sense. Ian
main.cpp

GtkWidget *Battery, *Temp, *Chip_volts; //these are GtkProgressBar derived from glade.

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

    printf("Entered gtk_init.\n");

        gtk_init (&argc, &argv);    //Gets gtk going.
        builder = gtk_builder_new ();
        gtk_builder_add_from_file (builder, "main.glade", NULL);
        window = GTK_WIDGET (gtk_builder_get_object (builder, "window"));
        Battery = GTK_WIDGET (gtk_builder_get_object (builder, "Battery"));
        Temp = GTK_WIDGET (gtk_builder_get_object (builder, "Temp"));
Chip_volts = GTK_WIDGET (gtk_builder_get_object (builder, "Chip_volts"));
        gtk_builder_connect_signals (builder, NULL);
        g_object_unref (G_OBJECT (builder));

        gtk_widget_show (window);
    printf("Main set up and showing window. \n");
// ****************************************************************
    gtk_main ();

    printf("Exiting MAIN. \n");

        return 0;
}

Hi,

I am learning GTK programming. I am using glade to create a UI and
then using GtkBuilder to show it.

When I run my application, it gives number errors regarding signal handlers:
------------------------------------------------------------------------------------------------------------------
(vaken_gtk:11467): Gtk-WARNING **: Could not find signal handler
'cb_ld_payload'.  Did you compile with -rdynamic?

(vaken_gtk:11467): Gtk-WARNING **: Could not find signal handler
'cb_loadkey'.  Did you compile with -rdynamic?

(vaken_gtk:11467): Gtk-WARNING **: Could not find signal handler
'cb_genkey'.  Did you compile with -rdynamic?
------------------------------------------------------------------------------------------------------------------
I have these functions in the same file. One of them look like:


----------------------------------------------------------------------------------------
static void cb_genkey(GtkWindow *wid,gpointer user_data)   {
     printf("Hi\n");
}
----------------------------------------------------------------------------------------

I found some other posts in which people got the issue solved after
putting proper compiler/linker flags. I am using Anjuta and tried a
lot of combination for passing  "-rdynamic" and/or
"-Wl,--export-dynamic". Yet my application always complain it cannot
find the signal handler.

My make -n output (removing echo) is:

Still the application complains about missing signal handlers. Full C
code at https://paste.gnome.org/pdg0iivsg
  Glade UI file at https://paste.gnome.org/ppnpbtkid

Please help.
