Here is the compiler output:

The depending codelines are:

    entry = new Gtk::Entry(0);
    entry->signal_activate().connect(sigc::mem_fun(this, 
&FileStepper::go));    <--works fine
    entry->signal_key_release_event().connect(sigc::mem_fun(this, 
&FileStepper::gofor));  <--- errorline
    hbox->pack_start(*entry, true, true, 0);
    entry->show();
[...]
void FileStepper::go(void)
[...]
bool FileStepper::gofor(Gdk::EventCrossing& event)
