title: Running FMU generated by Scilab on FMU SDK
body: <p>I have successfully exported an FMU from Scilab, and I want to simulate it via FMU SDK. But when I run it, it says:</p>
  
  <blockquote>
    <p>bin/fmusim_cs:symbol lookup error:PD_Controller.so:undefined symbol: summation</p>
  </blockquote>
  
  <p>...and the simulation was stopped.</p>
  
  <p>So what should I do now?</p>
