miniAudicle fails to build on Fedora 38

I am trying to build miniAudicle on Fedora 38 with gcc-13.1. The build fails with the following error message:

Probably a missing header.

Thanks for reporting! Looking at the build output, it appears you are using Qt5 whereas miniAudicle requires Qt6. You might also confirm this by running qmake --version to see which version of Qt it's using. If there are multiple versions of Qt installed on your system, select Qt6 (though I have not had to do this on Linux so I do not actually know how). Please keep us posted on this issue.

Ha, excellent. I thought that the port was done from Qt4 to Qt5. On linux, qmake binaries are postfixed by their versions. For qt6, it'll be qmake-qt6. And to start the build: make linux-alsa QMAKE=qmake-qt6. I close the ticket and thanks a lot for your answer !
