title: iPhone static library linking problem
body: <p>I having trouble with app that uses my static libs. Here is my setup:<br />
  I have 3 libs, Utilities, Share and Misc. Share and Misc depend on Utilities. They are compiling just fine when I compile them separately. Every lib is in its own XCode project.</p>
  
  <p>I want to build an app that uses features from Utilities and Share, so I added them into the project as direct dependencies. I see them listed in target "Link binary with libraries". I also see quite a lot of linking errors in the compilation results. Those error relate to 3rd parties code that is used in libraries, for example ASIHTTPRequest. Such 3rd party stuff I keep in one place and I just added path to that directory in "Header Search Paths".</p>
  
  <p>Example error:</p>
  
  <pre><code>objc-class-ref-to-ASIHTTPRequest in libShare.a(SomethingThatIsInLib.o)
  </code></pre>
  
  <p>It's confusing because libs alone are compiling just fine but when I try to compile the app, it's throwing such errors. What am I doing wrong?</p>
