title: Running Fortran on Xcode
body: <p>I am trying to run sample Fortran code on Xcode 4.3 using a 64-bit compiler and it will not build correctly. The main problem is that despite my best efforts, I cannot get the separate .f90 files to interact with each other, thus code like</p>
  
  <blockquote>
    <p>USE ElementModule, ONLY : ElementType</p>
  </blockquote>
  
  <p>will not work. Does anybody have any answers regarding how to get the separate .f90 files to read each other. I'm aware you have to include specific modules, but my search hasn't given me any straight answers regarding what those specific modules are.</p>
