C++11 seems to be possible. Some infos: 1. Wireshark requires at least Qt 5.2. 2. To build Qt5, from 5.7 C++11 is required: http://code.qt.io/cgit/qt/qt5.git/tree/README?h=5.7 I assume that building application for Qt 5.7 does not require C++11.
3. Ubuntu 14.04 LTS supports GCC 4.8.4, Qt 5.2.1 - but LTS End of Life is: April 2019 <-- C++11 is here 4. Ubuntu 16.04 LTS: GCC 5.3.1 , Qt 5.5.1, EOL: April 2021 5. Debian Jessie 8 supports GCC 4.9.2 and Qt 5.3.2, EOL: June 30, 2020 6. RHEL is safe? Qt 5.6 - 5.11, GCC 4.9.1? http://doc.qt.io/qt-5.6/supported-platforms.html 7. Window, macOS: supports everything :) 8. Fedora 26 (still supported?) has gcc 7.1: https://fedoraproject.org/wiki/Changes/GCC7 9. openSUSE:13.1 gcc 4.9 http://download.opensuse.org/distribution/13.2/repo/oss/ 10. SLES 12 is also not a problem (C++17?): https://www.suse.com/c/sles-12-toolchain-update-brings-new-developer-tools/ The question is: can we require C++11 right now? By the way: what is the minimum GCC version for Wireshark. I do not see any check for this in CMakeLists.txt. I assume we check a lot of compilers features instead. pt., 1 cze 2018 o 23:38 Guy Harris <[email protected]> napisał(a): > > On Jun 1, 2018, at 2:21 PM, Michał Łabędzki > <[email protected]> wrote: > > > Is there (still) a problem to switch to C++11 or C++14?
