我正在使用带有以下 Boost Signals2 代码的 Visual Studio 2012 Ultimate:在https://github.com/cfobel/boost_signals2/blob/master/hello_world_0.cpp 它会生成以下错误:

c:\program files (x86)\microsoft visual studio 11.0\vc\include\xmemory(348): error C4996: 'std::_Uninitialized_copy0': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators'
1>          c:\program files (x86)\microsoft visual studio 11.0\vc\include\xmemory(333) : see declaration of 'std::_Uninitialized_copy0'
1>          c:\libraries\boost_1_52_0\boost\signals2\detail\auto_buffer.hpp(192) : see reference to function template instantiation '_FwdIt std::uninitialized_copy<I,boost::variant<T0_,T1>*>(_InIt,_InIt,_FwdIt)' being compiled

此代码与 Visual Studio 2012 C++ 不兼容吗?仍然可以安全使用吗?最后,如何按照建议进行更改?谢谢

C4996是关于使用已被标记为弃用的函数的警告。由于您将其视为错误,也许您Treat Warning as Error (/WX)启用了该选项?

错误消息本身描述了禁用此选项的方法。将_SCL_SECURE_NO_WARNINGS符号添加到项目的预处理器定义中。
