[Anjuta-list] Signals can't connect

[Brian Lavender <brian brie com>]

I created a new gtk project using anjuta.  I used the glade designer
to create my app. It is a simple window with a button in it. Then I
wrote my callback functions. But when it runs, it says it can't find
the signal handlers. What am I doing wrong?

brian night-ranger:~/Projects/gtk-salsa/src$ ./gtk-salsa 

(gtk-salsa:5053): libglade-WARNING **: could not find signal handler 'on_button1_clicked'.

(gtk-salsa:5053): libglade-WARNING **: could not find signal handler 'on_window_destroy'.

Here is the source code for main.c and callbacks.c . I didn't include
the glade xml, but I created a window (callback named on_window_destroy
for destroy signal) and a button1 (callback named on_button1_clicked for
clicked signal).
