C ++ 11从同一类类型的构造函数调用构造函数 [英] C++11 calling constructor from constructor of same class type

问题描述

我被告知可能是由于C ++ 11的变化：

I was told the following was possible due to changes in C++11:

class SomeType  {
int number;

public:
SomeType(int new_number) : number(new_number) {}
SomeType() : SomeType(42) {}
};

但是当我尝试构建时，我得到一个错误：

But when I try to build I get an error:

"SomeType" is not a nonstatic data member or base class of class "SomeType"

error C2614: 'SomeType' : illegal member initialization: 'SomeType' is not a base or member

Visual Studio 2010中还不支持此功能吗？我需要配置一些东西来让这个构建吗？错误是什么？

Is this feature not yet supported in Visual Studio 2010? Do I need to configure something to get this to build? What is wrong?

推荐答案

VS2010不支持。 VS2010（或VS11）中不支持大多数C ++ 11功能

It's not supported in VS2010. Most C++11 features are not supported in VS2010 (or VS11 for that matter)

此处是VC10和VC11中支持的功能的图表。

Here is a chart of supported features in VC10 and VC11.
