title: Can't get ffi-rzmq zeromq gem working on Windows
body: <p>I've having trouble getting the ffi-rzmq gem to work on windows.</p>
  
  <p>I've installed the windows installer for ZeroMQ 2.2 from here:
  <a href="http://www.zeromq.org/distro:microsoft-windows" rel="nofollow">http://www.zeromq.org/distro:microsoft-windows</a></p>
  
  <p>And I've added C:\Program Files\ZeroMQ 2.2.0\bin to my PATH variable.</p>
  
  <p>I then installed the ffi and ffi-rzmq gems with</p>
  
  <pre><code>gem install ffi
  gem install ffi-rzmq
  </code></pre>
  
  <p>But when I start an irb and run:</p>
  
  <pre><code>require 'ffi-rzmq'
  </code></pre>
  
  <p>I get this message:</p>
  
  <pre><code>irb(main):001:0&gt; require 'ffi-rzmq'
  Unable to load this gem. The libzmq library (or DLL) could not be found.
  If this is a Windows platform, make sure libzmq.dll is on the PATH.
  For non-Windows platforms, make sure libzmq is located in this search path:
  ["C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/ffi-rzmq-0.9.3/lib/ffi-rz
  mq/../../ext/libzmq.dll", "/usr/local/lib/libzmq.dll", "/opt/local/lib/libzmq.dl
  l", "/usr/local/homebrew/lib/libzmq.dll", "/usr/lib64/libzmq.dll"]
  </code></pre>
  
  <p>The weird thing is that the Zero MQ installer doesn't seem to package a libzmq.dll, only <strong>libzmq-v100-mt.dll</strong></p>
  
  <p>I'm sure I'm doing something very obvious that's wrong, but I can't see what it is... can anyone help?</p>
  
  <p>Thanks.</p>
