std.cpp
--
#include \<vector>
#include \<iostream>
#include \<string>

     using namespace std;
     void a(string a)
     {
     		  cout\<\<" hello " \<\<a\<\<endl;
     }

s.d
--
module s;

import core.stdcpp.string;

     extern(C++)
     {
     	final void a(basic_string!char a);
     }

     main.d
     --
     void main()
     {
     	 import s;
       import core.stdcpp.string;
       auto i=basic_string!char("hello");
       	a(i);
     }

i've read the interfacing cpp on documentation,
ok then the compiler mesasge for this

libstdc++ std::__cxx11::basic_string is not yet supported; the 
struct contains an interior pointer which breaks D move semantics!

but with options AA="-D_GLIBCXX_USECXX11_ABI=0" on g++ ,
and BB="-version=_GLIBCXX_USE_CXX98_ABI" on dmd the message is :

Error: undefined reference to `a(std::string)`

how to solve the, std:string , std:vector,  std:optional ?

is there any article / links on general interfacing c++ problem 
solving ?

thanks
