Visual Studio 2015不会禁止错误C4996

Question

Visual Studio 2015 Community Edition gives the following error when compiling in debug, but not when compiling in release:

std::copy::_Unchecked_iterators::_Deprecate': Call to 'std::copy' 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'

---

I was able to trace back the source of this error to lines 214 and 242 of this third party library I'm using to write bitmap images. I don't fully understand what is going on in these parts, so I'd rather not mess with it.

---

I'm trying to disable this error, but Visual Studio won't let me. I've tried the following solutions that were suggested in the documentation , on StackOverflow, or elsewhere:

• Add 4996 to the "Disable Specific Warnings" field in Project Settings > Configuration Properties > C/C++ > Advanced.
• Add /wd4996 to the "Command Arguments" field in Project Settings > Configuration Properties > Debugging.
• Add #pragma warning (disable : 4996) at the top of the offending file, and/or above the offending function.
• Add _SCL_SECURE_NO_WARNINGS , _SCL_NONSTDC_NO_WARNINGS , _SCL_OBSOLETE_NO_WARNINGS , _SCL_SECURE_NO_WARNINGS_GLOBAL , and combinations thereof to the "Preprocessor Definitions" field in Project Settings > Configuration Properties > C/C++ > Preprocessor.
• Add the definitions from the previous solution with a #define directive to the top of the offending file.
• Add the definitions from the previous solution but prefixed with /D or with -D to the "Command Arguments" field.

But none of this fixes the issue for me.

What could possibly be the reason for Visual Studio to keep insisting on displaying this error?

Answer 1

定义NO_WARN_MBCS_MFC_DEPRECATION

Answer 2

Disabling warning 4996 has no effect on std::copy warnings. To suppress this warning place the following at the top of your source file:

#define _SECURE_SCL_DEPRECATE 0
#include <algorithm>

Answer 3

将_CRT_NONSTDC_NO_WARNINGS添加到预处理器定义。

Answer 4

In your stdafx.h:

#pragma warning( push )
#pragma warning( disable: 4996)
#include <algorithm>
#pragma warning( pop )
