Undefined symbols for architecture OpenHome iOS

I have Build and generate the Fat Libraries for the OpenHome by running the "Makefile" and by using "lipo" with all the .a by platforms.

The only changes I made to the "Makefile" are:

platform_cflags = -I$(sdkroot)/usr/include/ -miphoneos-version-min=2.2 -pipe -no-cpp-precomp -isysroot $(sdkroot) -DPLATFORM_MACOSX_GNU -DPLATFORM_IOS

to

platform_cflags = -I$(sdkroot)/usr/include/ -miphoneos-version-min=7.0 -pipe -no-cpp-precomp -isysroot $(sdkroot) -DPLATFORM_MACOSX_GNU -DPLATFORM_IOS

in line 169 and

nocpp11=no

the lipo -info shows

Architectures in the fat file: libohNetCore.a are: armv7 i386 x86_64 arm64 

I know the libraries are compiled wit libc++ because I have also run this command and that's the result

nm libohNetCore.a | c++filt | grep string | head -1
0000000000000110 T OpenHome::Net::CpDeviceCpp::GetAttribute(char const*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >&) const

The header files generated by the library have been imported using a Module because I am working on a Framework.

module OHNet[system]{

header "OHNet/include/OpenHome/Net/C/CpStack.h"
...

export *

}

The Apple LLVM 9.0 language c++ has been setup to libc++

However, I am facing an issue when I tried to compile.

The most weird thing is that when I add to the project a dummy cpp class this error goes away.

What Am I missing?

Sorry If the question might be a little bit not accurate.
