title: How can I compile 64-bit Mac programs with Free Pascal?
body: <p>I have an x86_64 library on my Mac compiled by GCC, and I want to link it with Pascal code compiled with Free Pascal 2.4. What options do I give to <code>fpc</code> to make it generate 64-bit code? Without any options, I only get 32-bit .o files.</p>
  
  <p>I'm using the <em>fpc-2.4.0.intel-macosx.dmg</em> download from SourceForge, but when I run <code>fpc -i</code>, the only target Macintosh platform it lists is "Darwin for i386," although the 2.4 release notes say it can target "64-bit Mac OS X (x86_64/ppc64)."</p>
