title: Can't create a .dll from Matlab Coder
body: <p>I am trying to convert some matlab code into a c dynamic library (.dll) using the Matlab Coder tool. I'm trying it on some simple sample code, but I keep getting the same error which I can't find a solution to.</p>
  
  <p>My code is:</p>
  
  <pre><code>function y = lbryTest(x, z) %#codegen
  %QUICKTEST Summary of this function goes here
  %   Detailed explanation goes here
  y = 1.0;
  a = x + z;
  b = x * a;
  y = b/3 + y;
  end
  </code></pre>
  
  <p>I've tried using the app version of coder as well as the command:  <code>codegen -config:dll lbryTest -args {2.0, 5.0}</code>
  and the build log, including the error, is:</p>

  <p>I can make a .lib from this code, but I need a .dll, which is proving difficult. It looks like I am missing some object file or matlab can't find it, but I don't know what to do about it.</p>
