C++11 calling constructor from constructor of same class type

问题

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) {}
};

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

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

回答1:

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

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