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.
