title: Activating C++11 support in Clang
body: <p>I've downloaded and built clang version 3.0 in order to play around a bit with C++11 features, however I get this error (even though I <strong>am</strong> using the <code>-Wc++11-extensions</code> flag).</p>
  
  <blockquote>
    <p>S:\llvm\code>clang++.exe  -Wc++11-extensions variadic.cpp<br>
    variadic.cpp:4:19: warning: variadic templates are a C++11 extension [-Wc++11-extensions]<br>
    template &lt;typename... Args&gt;  </p>
  </blockquote>
  
  <p>I've built clang with VS10 on Windows 7 (64bit) and the build passed successfully.</p>
  
  <hr>
  
  <p><strong>Edit:</strong> As @cli_hlt pointed out this is a warning not an error, the error is something I did not paste <strong><em>unable to execute command: program not executable</em></strong>. The root cause for that was that link.exe was not in the PATH. Once I ran from a VS command prompt all was well.</p>
