To disable this warning, use -D_SCL_SECURE_NO_WARNINGS

编译caffe时遇到问题:
错误 35 error C4996: ‘std::_Copy_impl’: 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’ D:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\xutility 2132 1 caffe_project

解决办法：
加入预处理器(项目属性—-C/C++—-预处理—-预处理器定义)：
_SCL_SECURE_NO_WARNINGS
