In your case, Your Project is not support your default deployment target so, you need to change it ( if 5.0 deployment target not available then update your system )

Answer 2

Projects created using Xcode 4.5 use libc++ implementation of the standard C++ library. But the libc++ library is available only on iOS 5.0 and later, So, if you want to enable deployment on earlier releases of iOS in your project, set the C++ Standard Library build setting to libstdc++ (Gnu C++ standard library).
