我这里有一个奇怪的情况。我想在VS2015中使用Botan加密库(因为项目的其他部分使用一些重的C++11代码,而VS2013无法编译),但我得到了一个相当长的编译错误(见下文)。
尝试了各种方法后,我得出结论,即使已经在编译的C++源文件中包含了botan头文件之一,编译器也会抛出下面的错误。现在我的文件中只有一行:

这是我收到的错误信息:

自从我能够编译和运行Botan测试以来,我有一种错过了点什么的感觉,但我不知道是什么。有人有这方面的经验吗? (顺便说一句:同样的代码可以很好地编译g++ 4.9)
std::_Wrap_alloc <Botan::secure_allocator <Botan::byte>>' 转换为 'const Botan::secure_allocator <_Newfirst> &':也许传递的
std::_Wrap_alloc对象需要一些类似于
operator *的间接操作,以获取一个可能可转换为
Botan::secure_allocator<_Newfirst>的
Botan::secure_allocatorBotan::byte` 对象? - Aleksey F.Botan::secure_allocator
