Question

Note, I have read and applied the answer to: Calling C++ member function from Luabind causes "No matching overload found", but this did not solve my issue.

I have a simple class that I expose to LUA via luabind

Here is the binding code:

void LogManager::luaBindImpl() const
{
    using namespace luabind;
    lua_State* state(Supervisor::getSingleton().getManager<LuaManager>()->state());

    // LogManager
    module(state)
    [
        class_<LogManager>("LogManager")
        .enum_("LogType")
        [
             value("Info", 1)
            ,value("Warning", 2)
            ,value("Critical", 3)
            ,value("Debug", 4)
        ]
        .def("log", &LogManager::log)
        .def("registerSource", &LogManager::registerSource)
    ];

    // Add to globals
    globals(state)["LogManager"] = this;
};  // eo luaBindImpl

And here is my LUA:

LogManager.registerSource("lol");

But I get the error mentioned in the title (this taken straight from my log file):

00:00:00:0520- lua:Exception - No matching overload found, candidates:
void registerSource(LogManager&,std::string const&)

I’ve been tearing my hair out over this and can’t see what I am doing wrong. Can anyone shed any light?! 🙂

Answer 1

In the Lua part, you need to use colon (:) instead of a dot:

LogManager:registerSource("lol");

And you do realize the global variable LogManager has the same name with the class LogManager; that way you won’t be able to use the enum constants, e.g. LogManager.Info will return nil.
