gcc 4.8.1有C ++ 11支持垃圾收集吗？ [英] Does gcc 4.8.1 have C++11 support for garbage collection?

问题描述

我问的原因是，网上有矛盾的信息。一方面，在 isocpp.org 它指出GCC 4.8.1具有完全实现的C ++ 11标准。另一方面， GCC C ++ 11支持页面说明没有Minimal对垃圾回收的支持和基于可达性的泄漏检测。因此，GCC 4.8.1真正的C ++ 11功能是完整的吗？

The reason I'm asking is, that there are contradictory pieces of information on the web. On the one hand on isocpp.org it states that GCC 4.8.1 has the C++11 standard implemented completely. On the other hand the GCC C++11 support page states that there is no "Minimal support for garbage collection and reachability-based leak detection". So is GCC 4.8.1 really C++11 feature complete?

推荐答案

请参阅 Bjarne Stroustrup C ++ 11常见问题）。因此，GCC 4.8.1是特征完整的，因为它实现了标准的所有强制性核心部分。

The support for garbage collection is optional by the standard (see Bjarne Stroustrup C++11 FAQ). Therefore, GCC 4.8.1 is feature complete since it implements all the mandatory core parts of the standard.

这些意见证明我的答案不清楚，我会更具体：只是谈论垃圾收集的核心支持。库部分是必需的。 GCC 4.8.1附带的libstdc ++的版本不完全符合C ++ 11（< regex> 目前不工作），垃圾ABI集合是缺少的功能的一部分。

The comments proved my answer unclear, I will be more specific: I was only talking about the core support for garbage collection. The library part is mandatory. The version of libstdc++ shipped with GCC 4.8.1 is not fully C++11-compliant (<regex> is not currently working for example), and the ABI for garbage collection is part of the missing features.
