title: Xcode Archive debug strip errors
body: <p>I am trying to integrate a large legacy C++ library with an iOS app. We are able to build and run on device but we are not able to archive the app. Archiving fails with the following error.</p>
  
  <p>Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/strip failed with exit code 1</p>
  
  <p>I did a "-v" on the strip and get a series of warnings similar to</p>
  
  <p>/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/strip: <strong>symbols referenced by relocation entries that can't be stripped in:</strong> /MyApp/DerivedData/SmartMusic_iPad/Build/Intermediates/ArchiveIntermediates/MyApp/IntermediateBuildFilesPath/UninstalledProducts/libMyLib-iOS.a(MyWhatever.o)</p>
  
  <p>It is not clear if this message is a warning or the reason for the failure. There are no other indications of problems in the strip output. Any clues?</p>
