Hey gang,

I'm on 15.0 and the qt that comes with it is qt5.

I'd like to upgrade to qt6, because I want to use the latest Quaternion (the one in the SlackBuilds is older than dirt).

Is it possible to 'upgrade' the qt in my Slackware 15.0 64? If/whan I 'make' it, do I actually *use* or should I use Should I uninstall the qt5 first if it's an install and not an upgrade?

Thanks for any ideas or information what I can/should do.

Replacing qt5 with qt6 will probably break stuff. Might be better to install qt6 alongside qt5. There's an SBo script for compiling (will take some time...)

You could just use the flatpak package. I have started using flatpak for a handful of things, namely duckstation, PCSX2, RPCS3 and it works great. Alien Bob has packages and a easy howto on how to set it up on his blog.

I built it for my brother for a slackware64 15.0 machine in order to use some advanced programming python utilities.

The qt6 package is available at slackbuilds.org at:

https://slackbuilds.org/repository/15.0/libraries/qt6/

Just beware on a virtualbox virtual machine I had to assign 4 processors, 16 GB RAM, and ensure I had 40 GB free disk space. On a slackware64 Current host running VirtualBox 7.0.14 with a AMD Ryzen 5 3400G with Radeon RX Vega 11 Graphics with 32 GB RAM, it took 16+ hours to build. Nevermind the dozens of prerequisite packages that needed to be built ahead of time.

It can be done if you have the resources and cohabitates nicely with qt5.

Qt5 and Qt6 are different.
https://doc.qt.io/qt-6/portingguide.html

Qt5 and Qt6 can both be installed at he same time as others have said.

And was added to -current on 28 February.

Okay, sounds good. Thanks everyone for the assistance. I have a AMD Ryzen 7 3700X with 24GB RAM, I guess I'll just limb a tree I felled yesterday for firewood for next winter and then sit and watch some movies until it finishes up compiling.

That's quite a machine you've got there. Can you let us know how long it takes to finish compiling?

It took about two hours to compile. I started it and even wrote the time down when it was started, then had things to do, like go and limb and buck a tree I felled the other day, then got back inside and sat and relaxed a little bit and watched a part of a movie before I remembered I was hoping to time it nice and as close to accurately as possible...it was done when I came in and sat down two hours and about 15 minutes later, heh. Sorry I didn't watch it closer, but I wanted the whole system to be left alone as I was expecting a lot longer than 2 hours, lol.

3h30, here with an old amd 6 cores, and 24 gin of memory.

Two hours is pretty impressive - the computer to compile qt6 and you to get the tree done and still have time to watch a movie.

Me, I would just have watched the movie

"time make ..." works just fine. You can even run it under "screen", and then log out. When you return, and see an idle system, you can see the "screen -r" to see the results.

And I'm building Qt6, just to show that it can work... or to show that I don't know what I'm talking about.

I was sure hoping there was such a thing. It seems that someone way back in the UNIX days would have come up with something like this just for shits and giggles and it become a standard piece of shell material.

Anyway, so how would one use that, like this for example?:
