Deploying ios app gets errors outside the project files..

Ramkumar Rammohan

While deploying ios applications got some error like wchar.h not found,

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/cstring:79: error: no member named 'strcoll' in the global namespace
using ::strcoll;

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/cstring:80: error: no member named 'strxfrm' in the global namespace
using ::strxfrm;

while click on the error open that files under the path //Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1
I'm sure that this not under my project..

I'm using mac os X Ei caption
and Xcode version 7.3.
and qt version 5.6.0
