title: Include path not found
body: <p>I recently upgraded to Mavericks OS and XCode 5. Eclipse is showing me the following warning with any C projects that I'm working on:</p>
  
  <blockquote>
    <p>Invalid project path: Include path not found >(/Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2/lib/gcc/i686-apple->darwin11/4.2.1/include).</p>
  </blockquote>
  
  <p>It is unable to find the standard C libraries like stdio. Hovering over <code>#includes &lt;stdio.h&gt;</code> tells me 'Unresolved Inclusion: stdio.h'.</p>
  
  <p>My project is able to compile in Eclipse, and via command line using gcc. Previously, before upgrading, Eclipse did not warn this.. Appreciate any assistance rendered.</p>
