我不是C ++程序员,我只是想在VS2010中基于crypto ++库编译一个旧的DLL(我认为是VS6),以便对其进行调试以了解其工作原理,因为我必须在其中编写一些代码。能够读取其加密内容的另一种语言

当我尝试编译DLL时,在这段代码中的第一个类型名上出现错误C2664

 #else /* _ITERATOR_DEBUG_LEVEL == 0 */
    _Vector_val(_Alloc _Al = _Alloc())
        : _Alval(_Al)
        {   // construct allocator from _Al
        typename _Alloc::template rebind<_Container_proxy>::other
            _Alproxy(_Alval);
        this->_Myproxy = _Alproxy.allocate(1);
        _Cons_val(_Alproxy, this->_Myproxy, _Container_proxy());
        this->_Myproxy->_Mycont = this;

        _Myfirst = 0;
        _Mylast = 0;
        _Myend = 0;
        }

    ~_Vector_val()
        {   // destroy proxy
        typename _Alloc::template rebind<_Container_proxy>::other
            _Alproxy(_Alval);
        this->_Orphan_all();
        _Dest_val(_Alproxy, this->_Myproxy);
        _Alproxy.deallocate(this->_Myproxy, 1);
        this->_Myproxy = 0;
        }
 #endif /* _ITERATOR_DEBUG_LEVEL == 0 */


我有一个Google,但我对答案的了解不足,无法更改它

构建中显示的实际错误是这样的

1>c:\program files (x86)\microsoft visual studio 10.0\vc\include\vector(441): error C2664: 'CryptoPP::AllocatorWithCleanup<T>::AllocatorWithCleanup(const CryptoPP::AllocatorWithCleanup<T> &)' : cannot convert parameter 1 from 'CryptoPP::AllocatorWithCleanup<T>' to 'const CryptoPP::AllocatorWithCleanup<T> &'


但是我不确定双击它所指向的行有什么关系,因为我似乎找不到它使用的任何单词?

非常感谢您的时间和协助

PS我看不到该库的较新版本,它可能会编译,因为我不知道它们是否更改了所用的任何加密方法

这是输出窗口的全部内容

在整个libraray中,唯一对文本“ max_size”的引用就是这些,它们全部位于一个名为secblock.h的文件中。

size_type max_size() const {return ~size_type(0)/sizeof(T);}    // switch to std::numeric_limits<T>::max later
size_type max_size() const {return 0;}
size_type max_size() const {return STDMAX(m_fallbackAllocator.max_size(), S);}

您可能需要更新Crypto ++。
