title: zxing in xcode 4.5 and ios 6
body: <p>As many of you noticed; zxing does not work in latest xcode (4.5/ios 6)</p>
  
  <p>Here is use case:</p>
  
  <blockquote>
    <ol>
    <li>checkout latest version from trunk (as some fixes were already added)</li>
    <li>create single view application in xcode 4.5 with ios 6.0</li>
    <li>use README to add dependencies, paths etc (just follow step by step)</li>
    <li>add zxingcontroller call to class (renamed to mm)</li>
    </ol>
  </blockquote>
  
  <p>Compilation fails both for simulator and device
  It shows 31 error like this one:</p>
  
  <pre><code>Undefined symbols for architecture i386:
    "std::string::c_str() const", referenced from
  </code></pre>
  
  <p>all 31 errors are similar, difference is in symbols name</p>
  
  <p>May be somebody knows how to solve it with this use case?</p>
  
  <p>p.s. if you have app from previous Xcode, it works. Problem is only if you create new app in Xcode 4.5</p>
