xcode build failure: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/cstring:70:9: No member named 'memcpy' in the global namespace; did you mean 'wmemcpy'?

Hello,
I am working with Unity 5.4.1 and XCode 8.0.
I am new to Unity and I am trying to build the xcode project generated for iOS.
I’ve got plenty of errors related to C++ code like the one below.
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/cstring:70:9: No member named ‘memcpy’ in the global namespace; did you mean ‘wmemcpy’?

Any idea what is wrong here?
Thanks

Hi Jessespike and Elenzil,

Unfortunately, I already tried that without success.
And I figured out that the issue is with a plugin I am using: Vuforia.
If I build the Xcode project right after it’s creation by Unity, I have an issue with Vuforia while linking:

“_getVuforiaLibraryVersion”, referenced from:
_VuforiaNativeIosWrapper_getVuforiaLibraryVersion_m782910513 in Bulk_Vuforia.UnityExtensions_1.o
(maybe you meant: _VuforiaNativeWrapper_getVuforiaLibraryVersion_m716106582, _VuforiaNativeIosWrapper_getVuforiaLibraryVersion_m782910513 )
ld: symbol(s) not found for architecture arm64

Thus I tried to change the build settings to look recursively into folders for the headers.
When I do that, I have the issues with the C++ symbols.

Any clue ?

Thanks,
