Hi,

I did as you suggested me but gcc 3.4.3 gives me this warning:

callbacks.c:605: warning: passing arg 5 of `ShowGtkMessageDialog' 
discards qualifiers from pointer target type

and the line 605 is:
response = ShowGtkMessageDialog (GTK_WINDOW 
(MainWindow),GTK_DIALOG_MODAL,GTK_MESSAGE_ERROR,GTK_BUTTONS_OK,g_strerror(errno));
