[Vala] [Genie] Problem with creating GtkSwitch widget

[Dmitriy Kovalenko <runningmaster gmail com>]

Hi all, I have a problem with creating GtkSwitch widget (and I
apologize for repeating themes).

This source code on Genie and Vala below works fine:

/* Genie */
[indent = 4]

init
    var gtk_switch_button = new Gtk.Button ()
    print "The button has been created"

/* Vala */
int main () {
  var gtk_switch_button = new Gtk.Switch ();
  print ("The button has been created\n");
  return 0;
}

But this source code generates errors:

/* Genie */
[indent = 4]

init
    var gtk_switch_button = new Gtk.Button ()
    print "The button has been created"

valac --verbose --debug --save-temps --pkg gtk+-3.0 gtk3switch.gs

Vala 0.11.7.1-263a8 and libgtk3.0-dev is installed (Ubuntu 10.10)

Please help me to understand what is this. thanks
