title: symfony2.3 with compass
body: <p>sorry for my bad English, I'm using symfony2.3 on windows8. When i try to use compass filter i get the error output: 
      "You must compile individual stylesheets from the project directory."</p>
  
  <p>Here is my assetic configuration:</p>
  
  <pre><code>assetic:
      debug:          %kernel.debug%
      use_controller: false
      bundles:        [ ]
      ruby: "C:/Ruby200-x64/bin/ruby.exe"
      #java: /usr/bin/java
      filters:
         cssrewrite: ~
         sass:
             bin: "C:/Ruby200-x64/bin/sass"
         compass:
             bin: "C:/Ruby200-x64/bin/compass"
  </code></pre>
  
  <p>And here is the view:</p>
  
  <pre><code>{% stylesheets 'bundles/walcore/css/*' filter='compass' %}
      &lt;link rel="stylesheet" href="{{ asset_url }}" /&gt;
  {% endstylesheets %}
  </code></pre>
  
  <p>When i try to use SASS filter everything work perfectly.</p>
