+1 QtSpeech will not work on all platforms without Qt Multimedia, so this dependency makes sense IMO. ________________________________ Von: Development <development-boun...@qt-project.org> im Auftrag von Volker Hilsheimer via Development <development@qt-project.org> Gesendet: Montag, 30.

To clarify, the problem is not upgrading an individual module here, but that an application running against Qt 6.6 will require Qt Multimedia, while an application running against Qt 6.4 or Qt 6.5 will not. But, I agree that we can assume that on systems where binary compatibility matters, all Qt modules are installed (or get installed when upgrading). > Anyhow, you could consider making the dependency optional at configure time. > Then users who don't need it could still configure without qtmultimedia - no > idea whether this is worth the hassle though. > > Regards > > Kai Ok. Given the footprint of Qt TextToSpeech, I don’t think it’s worth the hassle to make this configurable.
