链接到使用旧版C ++标准编译的库是否安全？ [英] Is it safe to link to libraries compiled with an older C++ standard?
问题描述
我使用C ++ 14标准编译了一堆库。即Boost，VTK和PCL。 PCL还包括仅头文件库Eigen。现在，我的项目需要一些C ++ 17的功能，所以我正在使用flag / std：c ++最新版本进行编译。我的
问题是，这会破坏与其他库的兼容性吗？如果是，我会得到编译时错误或警告，还是会编译成不安全的可执行文件？

这取决于您使用的功能。 最方便的方法是尝试。
/ std：c ++最新开关将推进Visual C ++实现的一组功能，每个新版本的C ++标准工作草案。目前，它将跟踪我们为拟议的后C ++ 14草案
标准添加的功能。当下一个标准被批准时，使用/ std：c ++最新选择的语义将由/ std：c ++ 17覆盖（假设下一个标准是C ++ 17，但是标准委员会工作组 ;永远不要惊讶）
和/ std：c ++最新将继续跟踪下一个草案标准的功能。换句话说，使用/ std：c ++ latest，您将始终获得当前实现的所有新功能的集合，默认情况下为。

I've compiled a bunch of libraries using the C++14 standard. Namely, Boost, VTK and PCL. PCL also includes the header-only library Eigen. Now, my project needs some C++17 features, so I'm compiling with the flag /std:c++latest. My question is, can this break compatibility with the other libraries? If it does, will I get a compile-time error or warning, or will it compile to an unsafe executable?
thanks for posting here.

It depends on the features you use. The most convenience way is to have a try.
The /std:c++latest switch will move forward the set of features implemented by Visual C++ with each new version of the C++ standards Working Draft. Currently it will track features that we add for the proposed post-C++14 draft standard. When the next standard is approved, the semantics opted-in with the /std:c++latest will be covered by /std:c++17 (assuming that the next standard is C++17, but the standards committee working group never ceases to surprise) and /std:c++latest will move forward to track the next draft standard’s features. In another words, with /std:c++latest, you will always get the set of all new features currently implemented and on by default.
