[英]Luabind compile time error Unable to deduce template argument
I'm getting a list of compile time errors that I don't understand. 我得到了我不理解的编译时错误列表。 I'm using the luabind library from sourceforge, version 0.9.1, and I'm trying to bind functions from MyGUI, I'm using Visual Studio 2012, and Lua 5.1.
我正在使用sourceforge(版本0.9.1)中的luabind库,并且试图绑定MyGUI中的函数,正在使用Visual Studio 2012和Lua 5.1。 The errors come up during the compilation of the cpp code below, despite seeming to originate in other files.
尽管似乎源自其他文件,但在以下cpp代码的编译过程中会出现错误。 The errors make me think I didn't define a signature correctly somewhere, however my IntelliSense isn't indicating any such problem.
这些错误使我觉得我没有在某处正确定义签名,但是我的IntelliSense并未指出任何此类问题。
The code in question: 有问题的代码:
LuaMachine.cpp (Stackoverflow complained about body length, so I put it on pastebin) LuaMachine.cpp (Stackoverflow抱怨体长,所以我把它放在pastebin上)
The errors given: 给出的错误:

EDIT: 编辑:
Through further research I have discovered the following are problem lines that are triggering these errors. 通过进一步的研究,我发现了以下引发这些错误的问题线。 These lines are in the wrapGuiManager function.
这些行在wrapGuiManager函数中。
luabind::def("destroyWidgets", &MyGUIManager::destroyWidgets) luabind :: def(“ destroyWidgets”,&MyGUIManager :: destroyWidgets)
luabind::def("unloadLayout", &MyGUIManager::unloadLayout), luabind :: def(“ unloadLayout”,&MyGUIManager :: unloadLayout),
These are the function declarations for those functions: 这些是这些函数的函数声明:
void unloadLayout(luabind::object& table); void unloadLayout(luabind :: object&table);
void destroyWidgets(luabind::object& table); void destroyWidgets(luabind :: object&table);
Both of these functions are unique in that they take a luabind::object& parameter. 这两个函数的独特之处在于它们都带有luabind :: object&参数。 They're supposed to be able to take a table from Lua that is used as an array full of MyGUI widgets.
他们应该能够从Lua中获取一个表,该表用作充满MyGUI小部件的数组。
I got it to work! 我懂了! :D the problem lines were
:D问题线是
luabind::def("destroyWidgets", &MyGUIManager::destroyWidgets)
and 和
luabind::def("unloadLayout", &MyGUIManager::unloadLayout)
Both of those functions took luabind::object&
, luabind didn't want to cooperate with those though, it instead wanted the functions to take luabind::object
without a reference, and just the object itself. 这两个函数都使用
luabind::object&
,但是luabind不想与它们合作,而是希望这些函数采用不带引用的luabind::object
,而只是对象本身。 So the correct function declarations would be: 因此正确的函数声明为:
void unloadLayout(luabind::object table);
void destroyWidgets(luabind::object table);
