title: Objective C: "_main", referenced from: Start in crt1.3.1.o error
body: <p>Trying to compile a iPhone/iPad application with SDK3.2 and am getting this error:</p>
  
  <pre><code>Undefined symbols:
  "_main", referenced from:
  Start in crt1.10.5.o
  Symbol(s) not found
  Collect2: Id returned 1 exit status
  </code></pre>
  
  <p>I think it's telling me that it's somehow trying to work with code from another SDK but searching the web has not provided any clear answers.</p>
  
  <p>Anyone able to guide me on this and what to look for?</p>
