加强与私有成员互斥奇怪的错误 [英] boost mutex strange error with private member

问题描述

我有一个奇怪的错误。

I have a strange error.

class INST
{
public:
boost::mutex m_mutex;
};

std::vector<INST> m_inst;

错误C2248：提高::互斥::互斥体：不能访问类中声明私有成员'的boost ::互斥体
看到的boost ::互斥::互斥体

error C2248: 'boost::mutex::mutex' : cannot access private member declared in class 'boost::mutex' see declaration of 'boost::mutex::mutex'

不过，我的另一个类是精细，

However, my other class is fine,

class VIEW
{
public:
boost::mutex m_mutex;
};

VIEW m_view;

我失去了一些东西在这里？我曾尝试申报m_mutex给私人，但仍然有同样的问题。

Am I missing something here? I have tried to declare m_mutex to private, but still have the same problem.

感谢。

推荐答案

互斥不能<一个href=\"http://www.boost.org/doc/libs/1_48_0/doc/html/thread/synchronization.html#thread.synchronization.mutex_types.mutex\">copied,所以你不能把它们放在这将复制互斥的容器。该错误很可能指的是互斥的私人拷贝构造函数。

mutexes can't be copied, so you can't place them in a container which would copy the mutex. The error is likely referring to the private copy constructor of the mutex.
