Pick e.g. Qt 5.15.x (it seems that the Qt 6 versions don't work with it), then the modules you use, and it will give you a complete list of every feature you can disable for that module. Although like Thiago says, not all of them are guaranteed to result in a successful build. There are a huge number of combinations, and Qt's CI already has to test with lots of different target platforms, so it only checks a limited set of features. If you're going to disable a lot of features, you'll probably want to get comfortable with Qt's contribution process in order to fix any build breakages. > -----Original Message----- > From: Interest <interest-boun...@qt-project.org> On Behalf Of Ben Cottrell > Sent: Thursday, 26 August 2021 4:28 AM > To: interest@qt-project.org > Subject: [Interest] Installation Sizes for Applications using Qt > > Qt is becoming more and more feature rich, but applications aren't getting > any smaller.
