Subject: [ruby-talk:21051] How To Display GUI in Linux shell ?

Hi,
   I'm new to RUBY. Hope some one can help.

I have one very simple ruby program. (Please see below).
When I try to run my program as below, it prompt me error.

[root@abc sample]# ruby test.rb 
/usr/local/lib/ruby/1.6/tk.rb:468:in `new': no display name and no $DISPLAY
environment variabl
e (RuntimeError)
        from /usr/local/lib/ruby/1.6/tk.rb:468
        from test2.rb:1:in `require'
        from test2.rb:1

##### test.rb
require 'tk'
root = TkRoot.new { title "Ex1" }
TkLabel.new(root) {
  text  'Hello, World!'
  pack  { padx 15 ; pady 15; side 'left' }
}
Tk.mainloop

   Please help.

Regards,
  Char
