Visual c++ 2015 cross platform mobile (android/ios) shared_ptr question

    Question

  • I am newbie in VS2015.

    I have tried to compile following test source which has shared_ptr.

    #include <string>
    #include <iostream>
    #include <memory>

    using namespace std;

    namespace ruby_base
    {
        class baseApi
        {
        public:
            virtual ~baseApi() {}



            static std::shared_ptr<baseApi> create_api();

            virtual std::string get_text() = 0;
            virtual void set_text(const std::string & text) = 0;
        };
    }

    and it gave me following error.

    baseApi.hpp(19,15): error : no type named 'shared_ptr' in namespace 'std'

    so i have checked whether std has shared_ptr or not. and it really doesn't have shared_ptr (but it has auto_ptr -_-)

    So now i have created simple MFC application and have checked whether it has shared_ptr. and it has shared_ptr.

    My quetion is why CrossPlatform Shared C++ library project doesn't support shared_ptr?

    How can i use shared_ptr in mobile shared library project? If i can't, Is there any substitute?

  • i have solved the problem.

    There is c++ language standard selection setting.

    Property

     -> c/c++

       --> language

          --> c++ language standard

             --> change default c++ standard to c++11

    I think default setting was C++03(-std=c++98).

    which is very old stl library (made in 1998), so it doesn't have shared_ptr.
