title: Makefile: 23: the recipe for the target "allmodes" failed
body: <p>We have an issue installing OMNeT 4.6; everything proceed well but in the final part we have this error message:</p>
  
  <blockquote>
    <p>Makefile: 23: the recipe for the target "allmodes" failed</p>
  </blockquote>
  
  <p>The system doesn't ask us to tape OMNeT (like it should be). We taped it anyway and everything proceeded okay.</p>
  
  <p>After that, we tried to install Castalia, but (like we had an error installing OMNeT - at least this is what we suppose-) we have another error message about liboppsim ( &amp; we suppose that the cause is the failed OMNeT installation).</p>
  
  <p>We tried the install the 4.6 version because Castalia doesn't support the OMNeT v5.x</p>
  
  <p>any help guys please??
  thanks in advance</p>
  
  <p>OS : Windows 10</p>
