g++ won't compile my complex template instantiation - c++

Question

I use MinGW latest version to compile the following code. I get the folowing message
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
Here is my code undressed from every thing not needed for this question
#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'
}
};
What is wrong with my call to the template method in class_object::add_method<...>()

Answer 1

It appears you mistyped function_type as funcion_type on line 27 of test.cpp.

Answer 2

Typo. funcion_type should be function_type.
