title: gcc error: Can't create precompiled header
body: <p>I have some useful typedefs on a header file called utypes.h. I have decided to use make and haven't found a way to compile it since then.</p>
  
  <p>When I execute <code>gcc -Wall -c utypes.h</code> to generate the .o object of utypes I get the following error: </p>
  
  <pre><code>"utypes.h:1 fatal error: can't create precomiled header types.h.gch: Permission Denied (EACESS)
  Compilation terminated.
  </code></pre>
  
  <p>What am I doing wrong here? Thanks.</p>
