Duplicate symbol
<p>I recently added some openfeint code to my classes and changed them to .mm </p>

<p>All of a sudden I get errors that duplicate symbols are found in the object files when building.</p>

<blockquote>
  <p>ld: duplicate symbol _audioPlayer in blah blah /Objects-normal/i386/Stage2.o and /Users/blah blah .build/Debug-iphonesimulator/blah.build/Objects-normal/i386/Stage1.o</p>
</blockquote>

<p>Why is it suddenly causing this error? What exactly is the error?</p>

<p>I have variables with the same name in different classes, it should be a problem?</p>

<p>Thanks</p>
