我得到与VS2013下面的代码的错误...的std ::矢量<性病::的unique_ptr <X>>成员变量引起问题
class Bob
{
private:
std::vector<std::unique_ptr<UnrelatedClass>> _aVector;
inline Bob(const Bob & other) {};
inline Bob & operator=(const Bob & other) { return *this; };
public:
Bob();
~Bob();
Bob(Bob && o);
};
class Fred
{
friend class Bob;
[... A few functions, Bob never used ...]
};
...其中编译具有去除的细friend class Bob;
。这是一个编译器错误?我不确定我做错了什么。
的错误如下:
c:\program files (x86)\microsoft visual studio 12.0\vc\include\xmemory0(615): error C2248: 'std::unique_ptr<Unrelated,std::default_delete<_Ty>>::unique_ptr' : cannot access private member declared in class 'std::unique_ptr<Unrelated,std::default_delete<_Ty>>'

的研究使我明白这是当Bob
复制产生同样的错误。因此,复制std::vector
,因此复制std::unique_ptr
我保证你不会“编译好”,因为你到处都丢失了分号。这段代码是谎言。 –
2缺少分号。固定。你现在可以帮我吗? – AStupidNoob
