Question

我正在尝试使用boost序列化序列化具有Plain-old-Data类型的简单类。但是，我唯一的要求是我不能使用RTTI。因此，我使用gcc 4.4.1为ARM Linux编译-fno-rtti，使用最新的Boost 1.47库。

所以这是我的班级：

#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) {}
};

我还没有实现实际的保存和加载功能（从查看Boost文档看起来非常简单）但我已经收到以下编译器错误：

make: *** [all] Error 1

所以...问题是，是否可以使用boost序列化序列化这个简单的类而不使用RTTI？我环顾四周似乎有可能使用一些增强宏和机器（#include＆lt; boost / serialization / extended_type_info_no_rtti.hpp＆gt;暗示这一点）但我是一个新的Boost用户，并且对如何使用非常无能为力继续。

PS：如果删除-fno-rtti，我的代码编译正常。

看看这个：

在RTTI关闭的情况下提升简单类的序列化（-fno-rtti）
