Hi @stevie2sheds.
Isn't fedora 40 using Qt version 6 ?
If so, you should compile Jamulus against Qt6.

Ah. Probably. I'm afraid I'm not a great expert, having enough knowledge to try things, but not enough to always get them right! So I was just following the instructions. With that being the case the compiling instructions are out of date and in need of review if they're instructing the wrong Qt framework. The Qt5 compile did work.

With most OS's I've used the only reason to compile is because the latest version of Jamulus isn't available in the repositories, if at all. With that being the case the compiling instructions probably need to be pointing to the latest tools rather than legacy ones. If there are too many variations then unfortunately the instructions may have to be more generic. That would be a shame because the current simple instructions do work.
