title: Why do I get the "unrecognised emulation mode: 32" error in Eclipse?
body: <p>How come I get this error when compiling with the -m32 argument?</p>
  <blockquote>
  <p>unrecognised emulation mode: 32</p>
  </blockquote>
  <p>I'm compiling using g++ on an x86_64 machine. It happens in one project, but not the other... Any hints?</p>
  <p><strong>Note:</strong> I'm using Eclipse CDT, so perhaps this is an IDE specific gocha?</p>
  <h3>Rephrased question</h3>
  <p>Perhaps a better question would be: What is the best method of building an x86 binary in Eclipse when running on an x86_64 machine?</p>
