I am also experiencing this issue on Fedora 40 with the Negativo drivers, and I believe this is a flatpak issue. Here is a GitHub issue detailing the problem. Allegedly it has been fixed, but I have updated to the latest commit and am still having the same issue, so I am unsure what to do (I’ve spent a number of hours trying to troubleshoot this). You might have luck just running a flatpak update
, as that is supposed to solve this issue (YMMV though, it didn’t fix it for me).
Can you paste the output of the build so we can see what specific package it is missing? Qt is not a single package, and it’s very likely that you need the developer package
qt-devel
and its associated libraries to build, not just the base package.
