title: CLIPS compilation
body: <p>I would like to compile CLIPS on Windows to get object files necessary to a binding with GNAT Ada.</p>
  
  <p>I have downloaded the package clips_core_source_630.zip which provides core  &amp; makefiles directories </p>
  
  <pre><code>makefile.g++
  makefile.gcc
  makefile.lib
  makefile.lib++
  makefile.win
  </code></pre>
  
  <p>I tried to compile with MinGW through the commands :</p>
  
  <pre><code>mingw32-make makefile.gcc
  </code></pre>
  
  <p>or</p>
  
  <pre><code>mingw32-make makefile.g++
  </code></pre>
  
  <p>But the answer is always : Nothing to be done ! And of course no object file has been generated.</p>
  
  <p>What am I doing wrong with that approach ?</p>
