title: How run clang from command line on Windows?
body: <p>At the Going Native conference last week, Chandler Carruth announced the existence of prebuilt binaries for running clang on windows. The same information is in a blog post <a href="http://blog.llvm.org/search/label/Clang" rel="noreferrer">here</a>. The intended audience for this is users of Visual Studio, but I want to run clang from the command line.</p>
  
  <p>I ran the installer and added the LLVM <code>bin</code> directory to my path, but when I try to compile "Hello world", I get this:</p>
  
  <pre><code>C:\&gt;clang hello.cpp
  hello.cpp:1:10: fatal error: 'iostream' file not found
  #include &lt;iostream&gt;
           ^
  1 error generated.
  </code></pre>
  
  <p>I can't find any information on how to configure things to run clang on Windows, and I'm guessing that after I figure out how to tell clang where to search for standard library headers, I'll have to tell it where to look for libraries to link with. Can somebody walk me through the setup step by step or point me to such a walkthrough?</p>
