Vala - fatal error: gtk/gtk.h - thrown error using Gtk libs

Source code in Vala:

using GLib;
using Gtk;

class MainWindow : Window  {

  public static int main (string[] args) 
  {    
    var window = new MainWindow();
    window.destroy.connect(Gtk.main_quit);
    window.show_all();

    Gtk.main();

    return 0;
  }

  public MainWindow()
  {
    this.title = "Title";
    this.set_default_size(400, 450);
    this.border_width = 10;

    this.window_position = WindowPosition.CENTER;
    this.destroy.connect(Gtk.main_quit);

    var btnClear = new Button.with_label("Button");
    add(btnClear);
  }
}

When compiling on Ubuntu 13.10, I got error:

user@dev:/path$ valac --pkg gtk+-3.0 "dev.vala" -o dev
/path/dev.vala.c:7:21: fatal error: gtk/gtk.h: No such file or directory
 #include <gtk/gtk.h>
                     ^
compilation terminated.
error: cc exited with status 256
Compilation failed: 1 error(s), 0 warning(s)

So, Ubuntu uses Gtk3. I've forcd to use gtk3.0 and make sure that libs for libgtk3 installed.

Secound question, If I want to develop Gtk 2.0 how can I do on Ubuntu if supports only Gtk 3?

You have to install the libgtk-3-dev package, too.

The -dev suffixed packages in Debian and Ubuntu based distros contain files necessary for development.

In addition there is also a libgtk2-dev package for Gtk+ 2.0 application development in Ubuntu.
