title: Visual Studio 2010 can't find cstddef
body: <p>I'm attempting to compile a C++ solution in VS 2010, but for some reason it can't locate the standard libraries.</p>
  
  <p>I'm including as so:</p>
  
  <pre><code>#include &lt;cstddef&gt;
  </code></pre>
  
  <p>VS is returning an error as so:</p>
  
  <pre><code>main.cpp(10): fatal error C1083: Cannot open include file: 'cstddef': No such file or directory
  </code></pre>
  
  <p>However, I check my installation directory, and it's right where it's supposed to be (VC\include), and this directory is a part of my include directory list in the project settings ($(VCInstallDir)include).</p>
  
  <p>Any ideas why this is happening, and how I can fix it?</p>
