I just check if Wireshark can be build using Qt5.10 and std=c++03, but this cannot be done - there is a need to have the compiler with C++11 (with correct flags). So if one day we drop support for Qt < 5.7, then we will "must have" C++11. Qt 5.6 LTS ends on 16.03.2019 (quite soon). Qt 5.9 LTS ends on 31.05.2020. But this is about Qt5 requirements in future, but we can still use C++11 from now. This will solve also my issue about "I have Qt 5.10 and nobody warns me about using C++11 features, except Ubuntu-based Petri-Dish {unexpected surprise}". sob., 2 cze 2018 o 17:09 Michał Łabędzki <michal.tomasz.labedzki () gmail com> napisał(a):
Just right. I assume that C++ is for UI, but in fact, it may be used also for dissectors, etc. You have my vote for "C++ for Qt5 GUI" and "C for the rest". I only think about C++11 together with Qt5. Qt4 was dropped so there is an occasion to standardize what standard of C++ we use. I use C++11 feature - list initialization [1]. My setup of Wireshark allow that because CMake set is as "-std=gnu++11", however, Petri-Dish fails on Ubuntu because of old "-std=gnu99". I do not know how it works because gnu99 is c99 + gnu extensions, but it is also C, not C++ (are there "reference&" for C?). I think the best solution is to switch to C++11. I hope gnu++11 is not required by Qt 5.7 or newer and this also can be changed to c++11.

I know we've had the C vs C++ discussion before and I'd still vote for keeping things where they are as far as "GUI" is C++ and epan + dissectors (i.e. libwireshark) as C. I'm a little more indifferent to the "peripherals"/tools. Other than some "shorthand" in syntax, I don't see the necessity to "upgrade". Are we missing out on some Qt features because of no C++ 11 support? -----Original Message----- From: Michał Łabędzki <michal.tomasz.labedzki () gmail com> To: Developer support list for Wireshark <wireshark-dev () wireshark org> Sent: Fri, Jun 1, 2018 5:21 pm Subject: [Wireshark-dev] Switch to C++11 or C++14 Hello, Is there (still) a problem to switch to C++11 or C++14? Petri-Dish seems to support it for Windows, but there is old standard used for Ubuntu. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe-- Michał Łabędzki
