推荐答案

如何在.h中初始化静态const std :: list?

不，您不能直接这样做.

How do I initialize a static const std::list in my .h?

No you can't directly do that.

要在类定义中初始化const静态数据成员，它必须是整数(或枚举)类型；如果此类对象仅出现在整数常量表达式的位置，则也是如此. 有关更多详细信息，请参见 C ++ 11标准在以下位置.

To initialize a const static data member inside the class definition, it has to be of integral (or enumeration) type; that as well if such object only appears in the places of an integral-constant expression. For more details, plese refer C++11 standard in the following places.

$9.4.2 Static data members and
$3.2 One Definition rule

但是，您可能可以执行以下操作: 如何在头文件中定义const static std :: string?

But, you MAY be able to do something like this: How can you define const static std::string in header file?
