Eventually, I got qt6-6.8.3 to build on #slackware 15.0. I’ve been working around other problems, but we’ve got frameworks 6.14.0 built, which should net us a Plasma 6.4.6 desktop if everything else falls into place. Not sure what other roadblocks I’ll hit, but it’ll make me giggle if I get it that far. Guess I’ll have to save the rest of the fun for after the holiday here, if I survive, that is.
