title: "dyld: Library not loaded" error
body: <p>i have successfully compiled static library and added it to the XCode project just like it's written in <a href="https://developer.apple.com/library/ios/technotes/iOSStaticLibraries/Articles/configuration.html" rel="nofollow noreferrer">documentation</a>:</p>
  
  <ol>
  <li>libclang.a file is in project directory (added file copy and group)</li>
  <li>libclang.a is listed in "Frameworks"</li>
  <li>i've added '-Objc' linker flag to 'Other linker flags'.</li>
  <li>libclang.a is listed in "Copy bundle resources"</li>
  </ol>
  
  <p>libclang.a is compiled for ios simulator:</p>
  
  <pre><code>MBA-Anton:llvm_34_build_i386 asmirnov$ lipo -info ../llvm_34_ios_i386_installed/lib/libclang.a
  input file ../llvm_34_ios_i386_installed/lib/libclang.a is not a fat file
  Non-fat file: ../llvm_34_ios_i386_installed/lib/libclang.a is architecture: i386
  </code></pre>
  
  <p>I'm able to build the project but i'm getting error while ios simulator starts the app:</p>
  
  <pre><code>dyld: Library not loaded: @rpath/libclang.dylib
    Referenced from: /Users/asmirnov/Library/Application Support/iPhone Simulator/7.1/Applications/D87A3FA9-7207-40B4-9EA0-5F06CEF6EF7B/StaticLibraryUsage.app/StaticLibraryUsage
    Reason: image not found
  </code></pre>
  
  <p>I have found similar questions but it seems i did everything what was recommended. Any thoughts?</p>
  
  <p>PS. I have libclang.dylib file but i'm not sure it's really needed since i have added libclang.a file in the project.</p>
  
  <p>PPS. I have compiled armv7 version of libclang.a and created fat library with both i386 and armv7 using <code>lipo</code>. After removing i386 version of libclang.a and adding fat version of libclang.a i have <a href="https://stackoverflow.com/questions/24051087/undefined-symbols-for-architecture-i386-lipo-error">multiple unresolved references for i386 arch build errors.</a></p>
  
  <p>PPPS. I have resolved "unresolved references" errors by adding all libLLVM*.a files in the project. but now i'm having original "dyld: Library not loaded".</p>
  
  <p>PPPPS: .m compile command-line:</p>
