[Eventmachine-talk] undefined method `associate_callback_target''

I''m implemented very simple "echo" server using evenmachine,
but I''m
getting: undefined method `associate_callback_target'':

/usr/local/lib/ruby/site_ruby/1.8/eventmachine.rb:1373:in `new'':
undefined method `associate_callback_target'' for

`run''

Am I doing something wrong?
I test is very simple:

      require ''rubygems''
      require ''eventmachine''

      module EchoServer
        def receive_data data
          send_data ">>>you sent: #{data}"
          close_connection if data =~ /quit/i
        end
      end

      EventMachine::run {
        EventMachine::start_server "127.0.0.1", 22122, EchoServer
      }

 telnet 127.0.0.1 22122

Thanks!

You are probably running the pure ruby version of EM. The method
#associate_callback_target is *not* defined in eventmachine/lib/
eventmachine.rb like it should be. If you look at the C++ source or
the Java source, you will find this method is a no-op.

Edit the eventmachine.rb source file and add:

def associate_callback_target
   nil
end

Save the file and try again; it should work.

I submitted a ticket (and patch) on this issue about 9 months ago but
now I can''t find it. I''ll resubmit...

Oops, that method should take a single parameter. Try

def associate_callback_target sig
   nil
end

How did you install eventmachine? You''re probably better off
installing it as a gem (it seems to be in site_ruby in your
installation). Rubygems should compile a C extension during the
install, which is much more stable and well tested than the pure ruby
version.
