QT 6.3.1

ukhooder

I'm trying to download and run Qt6.3.1, but I'm very inexperienced at this. I downloaded the source zip file, but I don't know how to make it run.
I'm using linux 64.
Any help would be appreciated.

@ukhooder How do you install it and how do you use it? Maybe better to try higher version of Qt6.4 or Qt6.5 while a lot of changes are being made.

I'm trying to get an older app I wrote working with a newly-installed ubuntu. I downloaded the latest QT but it wouldn't compile. So I'd like to recompile it with the same version of QT I originally made it with.

@ukhooder It is very likely you installed Qt6 under /opt. And qmake6 is not in the PATH. How do you run it? Do you use QtCreator?
if not, try to build your app with QtCreator and you can set Qt6 in the kit setting.

I downloaded the QT6 tar package, then extracted it. But I can't find anything in the folders that will run the program.

Hadn't thought about trying to get QT6 in the kit setting. I'll try that. Thanks for your help so far :-)

@ukhooder Not sure how you did it. It seems you have to build it from the source.
or get online installer from
https://download.qt.io/official_releases/online_installers/
to install a Qt version.
I saw the close selection is 6.3.2 which should not matter much.

@ukhooder hi and welcome to devnet,

Depending on your distribution, it might already provide Qt 6 and the corresponding development packages.

Otherwise, you should use the online installer, it will provide with pre-built version of Qt ready to use.
