g ++不會編譯我的復雜模板實例

Question

我使用MinGW最新版本來編譯以下代碼。 我得到以下信息

     y:/bbom/source/om0/basic/test.cpp: In static member function 'static void somecl
ass::init(class_object*)':
y:/bbom/source/om0/basic/test.cpp:68:50: error: no matching function for call to
 'class_object::add_method(void (&)(object*, arch&))'
y:/bbom/source/om0/basic/test.cpp:68:50: note: candidate is:
y:/bbom/source/om0/basic/test.cpp:27:54: note: template<class p_function> void c
lass_object::add_method(typename p_function::funcion_type)
make.exe: *** [y:/bbom/bin/om0/basic/test.a] Error 1

這是我的代碼從這個問題不需要的所有東西中脫穎而出

#include <exception>

class exception : public std::exception
{
    public:
    exception() {}
    exception(const exception &);
    ~exception() throw() {}
    virtual const char *what() const throw();
};

typedef unsigned id, version;
class class_object;

class object
{
    public:
    virtual ~object() {}
    void *get_method(id);
    class_object *get_class_object();
};

class class_object : public object
{
    public:
    template <class p_function>
        void add_method(typename p_function::funcion_type p) 
            {add_method2((void *)p, p_function::function_id);}
    void add_method2(void *, id);
};

template <typename p_func, id p_id>
class function
{
    public:
    typedef p_func function_type;
    enum {function_id = p_id, };
    function(object *p) {m_func = (p_func)p->get_method(p_id);}
    p_func m_func;
};

class iface : public object
{
    public:
    iface(object *p) : m_object(p) {}
    static void init(class_object *) {}
    object *m_object;
};

class arch;
class archivable : public iface
{
    public:
    typedef void (*archive_func_type)(object *, arch &);
    typedef function<archive_func_type, 0x5afeb287> archive_type;
    archivable(object *);
    archive_type archive;
};

class someclass : public object
{
    public:
    static void archive(object *, arch &)
    {
    }
    static void init(class_object *p)
    {
        p->add_method<archivable::archive_type>(archive);
        // the compiler says this call cannot be matched to 
        // add_method declared in class 'class_object'
    }
};

我對class_object :: add_method <...>（）中的模板方法的調用有什么問題

Answer 1

似乎您在funcion_type的第27行funcion_type function_type funcion_type為test.cpp 。

Answer 2

錯別字。 funcion_type應該是function_type 。
