title: Is a Linux executable "compatible" with OS X?
body: <p>If you compile a program in say, C, on a Linux based platform, then port it to use the MacOS libraries, will it work?</p>
  
  <p>Is the core machine-code that comes from a compiler compatible on both Mac and Linux?</p>
  
  <p>The reason I ask this is because both are "UNIX based" so I would think this is true, but I'm not really sure.</p>
