Ah, sorry, that is the result of my recent change. I had checked here

https://wiki.wireshark.org/Development/Support_library_version_tracking

which says that 5.9 and 5.12 had already been required by Wireshark 3.0 and 3.2 so I went ahead and used it.

The table of Qt versions shows which versions have been used in Wireshark installers for Windows and macOS. Determining the versions available on specific Linux distributions is a bit more of an artform but can be gleaned from the tables further down. 

 

Does it actually compile and work on 5.6 except for that change?

QT 5.6 is a long term support release and there are some distributions stuck on it. I can change my recent commit if we don't want to bump the required version.

In a VM where I build Wireshark, I am getting this error on master:

My installed version of Qt appears to be 5.6.2.

Looking at CMakeLists.txt, there are various checks for Qt5Widgets, but the earliest supported version looks like 5.3?

I think  https://doc.qt.io/qt-5/qtglobal.html#qAsConst  was introduced in 5.7.

Do we want to bump the minimum versions?
