Re: [luabind] No Matched Arguments

[Bjorn M. <Bjo...@mi...>]

It looks to me like you're trying to map a static function. When you use th=
e : operator in Lua, you are asking it to "secretly" pass "self", equivalen=
t to C++ "this" along as the first parameter. When you use the "." operator=
, this secret "self" does not happen. This is why, when using the ":" opera=
tor, LuaBind complains that no match could be found for (<OgreApp>, string,=
 string, string).

Have you tried mapping the static function as a global function to see if t=
his works? Alternatively, try mapping a version that uses const char* inste=
ad of string.

Sorry, it's no 100% solution, but perhaps enough to get you started.

Subject: [luabind] No Matched Arguments

I have just started playing with LuaBind and so far it seems like it's goin=
g to be a great thing!  I am running into a bit of a problem though.  I hav=
e a class called OgreApp that has a method called addPath that looks like t=
his:

    void OgreApp::addPath(std::string group, std::string type, std::string =
path)

here is how I've tried setting it up in luabind:

    luabind::module(luaState)
    [
        luabind::class_<OgreApp>("OgreApp")
        .def("addPath", (void(OgreApp::*)(std::string, std::string, std::st=
ring))&OgreApp::addPath)
    ];

and I call it in lua like this:

OgreApp.addPath(group, type, path)

but I got the following error

     no overload of 'OgreApp:addPath' matched the arguments(string, string,=
 string) candidates are: OgreApp:addPath(string, string, string)

I noticed the fact that it says OgreApp:addPath, so I tried calling it like=
 that instead and got this error

     no overload of 'OgreApp:addPath' matched the arguments(<OgreApp>, stri=
ng, string, string) candidates are: OgreApp:addPath(string, string, string)

What am I doing wrong?
