使用Boost.Serialization进行序列化

我一直在尝试序列化，但每次都会遇到像这样的错误：

error: 'class std::vector<int, std::allocator<int> >' has no member named 'serialize'

以下是我的源代码和序列化方法，需要注意的是我使用了boost.serialize库。

template <class E, class T>
class heap{

    vector<E> * hp;
    int index;//index is pointing to first empty place after the last element
    int maxsize;

    T comp;//comparable object designed to compare the objects

private:
    friend class boost::serialization::access;
    // When the class Archive corresponds to an output archive, the
    // & operator is defined similar to <<.  Likewise, when the class Archive
    // is a type of input archive the & operator is defined similar to >>.
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {

        ar & hp;
        ar & index;
        ar & maxsize;
        ar & comp;
    }

public:
    //default empty constructor
    heap(){

        hp = new vector<E>(MAX);
        index = 0;
        maxsize = MAX;


    }
.

}

然后我把这一行 ar&hp; 改成了

for(int i = 0; i < hp->size(); i++)
   ar & hp->at(i);

我遇到了更糟糕的错误，比如：

/../../../../boost/boost_1_48_0/boost/archive/text_oarchive.hpp:100: undefined reference to `boost::archive::text_oarchive_impl<boost::archive::text_oarchive>::text_oarchive_impl(std::ostream&, unsigned int)'
debug/main.o: In function `~text_oarchive_impl':

包含<boost/serialization/vector.hpp>。
不要动态分配vector。
不要忘记链接Serialization库，它不是仅头文件库。
