title: Building C++ not working in OSX 10.9
body: <h3>Update:</h3>
  <p>I solved the problem in the end by reinstalling command line tools, as shown in this <a href="http://www.computersnyou.com/2025/2013/06/install-command-line-tools-in-osx-10-9-mavericks-how-to/" rel="noreferrer">link</a>.
  Sorry for the trouble!</p>
  <h3>Initial question</h3>
  <p>I have just upgraded to OSX Mavericks and I cannot make the compiler work anymore.
  I've been using gcc48 from macports with vim/sb2 and everything was working just fine. Now any library that I include gives tons of errors. I am not very experienced and I do not know what to do, or what to search for. I just want it to work like before. Here is what is says when compiling a basic &quot;hello world&quot; program:</p>
  <pre><code>In file included from /opt/local/include/gcc48/c++/bits/postypes.h:40:0,
               from /opt/local/include/gcc48/c++/iosfwd:40,
               from /opt/local/include/gcc48/c++/ios:38,
               from /opt/local/include/gcc48/c++/ostream:38,
               from /opt/local/include/gcc48/c++/iostream:39,
               from ceva.cpp:1:

  #include &lt;wchar.h&gt;
  </code></pre>
