Question

我正在与Lua和Luabind合作开发一个C ++项目。现在，在我想要导出到C ++的每个类中，我编写一个静态方法注册如下：

在Button.h中：

static luabind::scope Register();

在Button.cpp中：

luabind::scope falcon::Button::Register()
{
    return 
        luabind::class_<Button, Button*>("Button")
        .def(luabind::constructor<float, float, float, float>());
}

对于我已经导出到Lua的每个班级，这都很好。但对于Button.cpp来说，这似乎不起作用。

我收到以下链接器错误：

有人有任何想法吗？

我刚刚通过定义＆amp;来解决错误在头文件中声明函数...也许任何人都可以向我解释为什么必须为这个类做这个而不是，比方说，其他10个我想要注册Lua？

这有点奇怪，因为我在.cpp中的其他类中实现了这个函数......

如何解决LNK2005：已定义
