Qt 5.14+ on ubunut 20.04

xdgbsdb

Hi,

i've installed QT 5.15 to /opt/ in Ubuntu 20.04. I've also added /opt/Qt/5.15.2/ to my PATH.

Running qtdiag continues to show the older version installed. 5.12.x.

I've seen warnings not to simply delete an existing Qt installation, so haven't tried that yet.

With /opt/ at the front of my PATH I would have hoped the newer version is what would be picked up.

thank you for any suggestions about how I can upgrade Qt.

for what i am doing I need QRecursivemutex, which means 5.14 or greater.

thanks!

Hi and welcome to devnet,

Are you trying to build your project on the command line ?
If so, use the full path to the qmake executable of the Qt version you want to use.

That's the proper way to build with different versions of Qt.

@xdgbsdb type command:
which qmake
and show the results here.

Hi per the direction of a member of the QGIS dev mailing list, i've upgraded to ubunutu 22.04 which includes qt 5.15 and I'm tentatively all set.

thank you for the responses!

@xdgbsdb ubunutu 23.04 is available as well. You can get a higher version of Qt there.
