Fibers error #2

Closed lindemannrichard closed 10 years ago

lindemannrichard commented 10 years ago

I have tried to test a simple example: 

require 'krakow'

producer = Krakow::Producer.new(
  :host => 'localhost',
  :port => '4150',
  :topic => 'target'
)
producer.write('KRAKOW!', 'KRAKOW!')

tried all MRIs 2.x 

ruby -v
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin13.0]

But what I get is this error:

Does that means that Celluloid does not work with MRI Rubies 2.x ? (and as consequence => krakow fails)

lindemannrichard commented 10 years ago

It seems that adding

require 'celluloid/autostart'

fixed the problem. I think that this might be mentioned in the README.

chrisroberts commented 10 years ago

ah, this looks like my mistake not having that include by default. will add. thanks for the report!
