title: How to fix "Couldn't load shared library 'libgdx64.so' for target: Linux, 64-bit"
body: <p>I am trying to use the headless LibGDX for unit testing, but when I run the test I get this error:</p>
  
  <blockquote>
    <p>Couldn't load shared library 'libgdx64.so' for target: Linux, 64-bit</p>
  </blockquote>
  
  <p>I read <a href="https://github.com/libgdx/libgdx/issues/1127" rel="nofollow">here</a> that I need to add <code>gdx-natives.jar</code>. Is this correct, and where can I find this file?</p>
  
  <p>Also, where in my project should I add the file?</p>
