The function is declared as such

void update_status() {
/*
    Copyright (C) 2008-2010 Stefan Haller
*/
 gchar * tooltip = NULL;

 if (error != NULL) {
  tooltip = error;
// gtk_status_icon_set_from_file(status, ERROR_ICON);
 } else {
  tooltip = _("DesktopNova");
// gtk_status_icon_set_from_file(status, NORMAL_ICON);
 }

// gtk_status_icon_set_tooltip(status, tooltip);
}

the variable tooltip is declared and assigned a value.
But in either case of the if, a value is assigned to this variable, hence there is not need to set it.
--> Compiler warning

However may be an option of the gcc : cc1 is telling it to treat all warnings as errors.

I tried to remove the NULL assignment, keeping only the gchar * tooptip; but it ended with the same error.
 I have no experience of gtk programing.
