MSVC 2015 / Wall有很多没有用的消息 [英] MSVC 2015 /Wall has lots of not useful messages

问题描述

即使我有一个空的程序保存包含字符串，即使我抑制警告包括，我仍然得到很多警告。

Even if I have an empty program save for include string, even if I suppress warnings around includes, I still get lots of warnings.

要重现： p>

To reproduce:

# CMakeLists.txt

add_executable(main main.cpp)

# All warnings, and treat as errors
if(MSVC)
    set_target_properties(main PROPERTIES COMPILE_FLAGS "/Wall /WX")
endif()

---

---

// main.cpp

#pragma warning(push, 0) // suppress warnings from dependencies
#include <string>
#pragma warning(pop)

int main()
{
}

即使只是这样，我得到了一些警告，第一个是...

Even with just this, I get pages of warnings, the first of which is...

main.cpp(8): warning C4710: 'int swprintf_s(wchar_t *const ,const std::size_t,const wchar_t *const ,...)': function not inlined

这是否是预期的？或者我做错了什么？

Is this expected? Or did I do something wrong?

我应该选择警告抑制，并且在我写的每个文件中都禁止他们吗？

Should I cherry pick warnings to suppress, and supress them in every file I write?

或者，我应该选择启用哪些警告？

Alternatively, should I cherry pick which warnings to enable? But that could become a tediously long list, which I would have to maintain as new checks become available.

推荐答案

我查了一下，警告，并指向我通常禁止的此警告列​​表： https：// msdn.microsoft.com/en-us/library/23k5d385.aspx 。

I looked up that warning and it pointed me to this list of warnings that are normally suppressed: https://msdn.microsoft.com/en-us/library/23k5d385.aspx.

您可以查看该列表，并全局禁止您的警告不在乎。我不知道如何做一个全局抑制。

You can review that list and do global suppress of the warnings that you don't care about. I'm not sure how to do a global suppress. But that particular warning seems useless.
