C ++：什么GNU G ++参数？ [英] C++: What GNU G++ parameters?

问题描述

可能重复：

C / C ++编译器的最佳编译器警告级别

$ b b

GCC有数千个选项来添加更多警告;我希望 -Wall -Wextra -pedantic 所有有用的，但只是现在我遇见了 -Woverloaded-virtual 这似乎对我很好。

GCC has thousands of options to add more warnings; I was hoping that -Wall -Wextra -pedantic included all the useful ones, but just now I met -Woverloaded-virtual which seems really nice to me.

推荐答案

不是完全相同的类别，我总是使用 -Werror 编译来将警告标记为错误。非常有用。

Not quite the same category but I always compile with -Werror to flag warnings as errors. Very useful.

要使用第三方标题，我通过 -isystem code> -I ...否则这些标头中的警告将破坏构建。

To make this work with 3rd party headers, I include those headers via -isystem instead of -I … otherwise warnings in those headers will break the build.

还有 -Weffc ++ ，它会警告Meyers的 Effective C ++ 中列出的特定问题。但是，我发现这太苛刻了。例如，它警告不声明虚拟析构函数的基类。理论上，这是非常好的，但我正在使用一个模板库，使用继承代码重用（和政策类），显然他们没有（也不需要）虚拟析构函数。

There’s also -Weffc++ which warns for specific issues outlined in Meyers’ Effective C++. However, I’ve found this too harsh. For example, it warns for base classes that don’t declare virtual destructors. In theory, this is very nice but I’m working on a template library that uses inheritance for code reuse (and policy classes) and obviously they don’t have (nor need) virtual destructors.
