[luabind] No overload of 'class:method' matched the arguments (), candidates are: class:method()

[Alexander G. <agl...@gm...>]

Hi, all!

I'm using luabind CVS version from January 4th, 2005 with Lua 5.0.2.

I have some number of classes I want to be able to derive from in lua
code. Most of derived lua classes would need to use some additional
c++ functionality, it is not needed in c++ base classes.

I have following code:

== [ C++ ] ==

class real_class
{
public:
  virtual void base_foo()
  {
    printf("base_foo\n");
  }   
};

class my_mixin
  : public luabind::wrap_base
{
public:
  std::string mixin_foo()
  {
    return "[foo is called]";
  }
};

class my_wrapper
  : public real_class
  , public my_mixin
{
public:
  virtual void base_foo()
  {
    call<void>("base_foo");
  }

  static void default_base_foo(real_class * ptr)
  {
    return ptr->real_class::base_foo();
  }
};

void register_stuff(lua_State * pState)
{
  using namespace luabind;
  luabind::module(pState)
  [
    class_ < real_class, my_wrapper >("real_class")
      .def(constructor<>())
      .def("base_foo", &real_class::base_foo, &my_wrapper::base_foo)
      .def("mixin_foo", &my_mixin::mixin_foo)
  ];
}

// Here goes lua and luabind initialization and call to
register_stuff(). Then lua script
// is loaded and executed.
== [ LUA script ] ==
class 'real_derived' (real_class)

function real_derived:__init() super()
  self.name = self.mixin_foo()
end

function real_derived:get_name()
end

rd = real_derived()

When this code is executed, the following error message is displayed:

    no overload of  'real_class:mixin_foo' matched the arguments ()
    candidates are:
    real_class:mixin_foo()

Where am I wrong?

I can provide more details if needed.

Thank you in advance,
Alexander.
