c++ - 在关闭 RTTI 的情况下 boost 简单类的序列化 (-fno-rtti)

Question

我正在尝试使用 boost 序列化来序列化具有 Plain-old-Data 类型的简单类。但是，我唯一的要求是不能使用 RTTI。因此，我正在使用 gcc 4.4.1 for ARM Linux 和最新的 Boost 1.47 库使用 -fno-rtti 进行编译。

这是我的类(class):

#include <boost/archive/xml_oarchive.hpp>
#include <boost/archive/xml_iarchive.hpp>

class libNemoMemento
{
    friend class boost::serialization::access;
    private:
        template<class Archive>
        void serialize(Archive & ar, const unsigned int version)
        {
            ar & BOOST_SERIALIZATION_NVP(temperature);
            ar & BOOST_SERIALIZATION_NVP(voltage);
            ar & BOOST_SERIALIZATION_NVP(bandwidth);
            ar & BOOST_SERIALIZATION_NVP(power);
        }
        int temperature;
        unsigned int voltage;
        unsigned int bandwidth;
        unsigned char power;
    public:
        libNemoMemento(void) {}
        virtual ~libNemoMemento(void) {}
};

我什至还没有实现实际的保存和加载函数(从查看 Boost 文档来看它们似乎非常简单)但我已经收到以下编译器错误:

In file included from /home/me/prebuild/third-party/boost/include/boost/serialization/detail/shared_ptr_132.hpp:29,

make: *** [all] Error 1

所以..问题是，是否可以在不使用 RTTI 的情况下使用 boost 序列化来序列化这个简单的类？我环顾四周，似乎可以使用一些 boost 宏和机制(#include < boost/serialization/extended_type_info_no_rtti.hpp > 暗示这一点)，但我是一个新的 Boost 用户，对于如何进行非常无能为力。

PS:如果我删除 -fno-rtti，我的代码可以正常编译。
