title: What do these Dsymutil Warnings mean in XCode 4.5?
body: <p>I am linking a static framework for iOS, against an armv7 ios 6 application, I suspect that the original binaries are from XCode 3.x and were compiled with GCC, and that I'm now linking it using CLang compiler.  I do not have the source code for the framework, only the binaries:</p>
  
  <pre><code>(null): warning: (armv7) /.../DerivedData/.../armv7/HardwareObjectFile.o unable to open object file
  </code></pre>
  
  <p>I get 69 warnings like the above, one for every .o file linked into the static framework.</p>
  
  <p>Is this warning serious for any reason?  I have simplified the giant path which appears to indicate that the binary files in the library have hardcoded a path in "/Users/somedeveloperthatisntme" that could hardly help but Not Exist since I'm using this library on a computer that doesn't even have a folder named "Users/somedeveloperthatisntme".</p>
  
  <p><a href="http://developer.apple.com/library/Mac/#documentation/Darwin/Reference/ManPages/man1/dsymutil.1.html" rel="noreferrer">Dsymutil</a> appears to be a tool to "manipulate archived DWARF debug symbol files", although I know precisely nothing about what it is and what it does, notwithstanding the thorough documentation from Apple, which tells me what, but never ever, why.  What is it doing, and what will this warning mean for me? I suspect I need a new library/static-framework from the vendor to clear this up?</p>
  
  <p><em>Update:</em> I am unable to solve this and it appears the cause lays with very old binaries compiled by a very old XCODE version, shipped as part of a mobile framework from a third party vendor.  The issue in this case would be resolved by having that vendor rebuild their library, something I asked them to do because the warnings drove me nuts, but which they seem unable to do. In the end I ditched their technology and replaced it with something else. (Grin)</p>
