How to get Qt Version from builded application?

[TomNow99]

Hi,

Some time ago, I build application for my Windows OS. Now I would like to know which QT I used to build it. I know that was QT 5, but maybe 5.9, maybe 5.11, maybe 12 etc. How can I check that? Of course I have that application exe and files like Qt5Core.dll and platforms.

Not sure, but if you right click on Qt5Core.dll there is something like a Version tab or detailed properties. There you should see information in the .dll which should/might indicate the detailed Qt5 version number?

Not sure about Windows, but on Linux it's just:

nm myApp | grep Qt_6 > /dev/null
echo $?

If it prints 0, it's a Qt 6 program, 1 otherwise.
