C++11 Can'；将std:：vector序列化为谷物

我对序列化还不熟悉，而且我在用。下面的示例说明了问题：

class MyClass
{
    int x, y, z;

    class MyOtherClass
    {
        string name, description;

    public:

        template<class Archive>
        void serialize(Archive & archive)
        {
            archive(name, description);
        }
    };

    vector<MyOtherClass> Victor;
    vector<int> ints;

public: 

    template<class Archive>
    void serialize(Archive & archive)
    {
        archive(x, y, z, ints); // error C2338: cereal could not find any output serialization functions for the provided type and archive combination.
    }
};

---

我做错了什么？

很可能是因为您没有阅读文档部分，忘记了包含相关的头文件，例如

#include

。你的例子不完整，但这是我的猜测。斯佩克拉斯，你说得对，谢谢。我只阅读了“快速入门”页面和文档主页上链接的其他几页。我现在没有时间测试代码现在是否工作，但我预计不会有任何进一步的问题。再次感谢！
