You are not adding correct compiler in build Setting.

You add (Apple LLVM 4.2 Compiler)Goto Build Setting And select this Compiler...

try this one...

  • above error is solve but new error is coming .../cpp/core/src/zxing/BinaryBitmap.h:33:7: Private field 'cached_y_' is not used – John Marry Jun 11 '13 at 06:58
  • if your error is solved accept this answer..what is cached_y_ – Jitendra Jun 11 '13 at 06:59
  • for the another error generated you could try this one -Werror turns warnings into errors. A lot of people use this option to force themselves to write very clean code. Taking this one out should be enough. – Agent Chocks. Jun 11 '13 at 07:45
