Summary: KWin already used C++14 constructs in a conditional way. This doesn't make much sense today, it's better to just require C++14. For KWin only gcc and clang are currently compilers of relevance. Gcc supports C++14 since version 5 and defaults to C++14 since 6.1 [1]. Clang supports C++14 since version 3.4 [2]. An overview of compiler support in various distributions: * Debian stable (stretch): gcc 6.3, clang 3.8 * Debian oldstable (jessie): 4.9, clang 3.5 * Ubuntu 17.04: gcc 6.1, clang 3.8 * Ubuntu 16.04: gcc 5.3, clang 3.8 * openSUSE Tumbleweed: gcc 7.1, clang 4.0 * openSUSE Leap 42.3: gcc ?, clang ? [3] * FreeBSD: clang >= 34 in ports * Slackware 14.2: gcc 5.3 This overview shows that every distro out there has at least one supported compiler which can still compile KWin with this change.

It seems that there is gcc 7 available, but gcc package is 4.8 Test Plan: Compiles on my neon system Reviewers: #plasma Subscribers: plasma-devel, kwin, #kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D6634 |
