That's correct, the virtualkeyboard module provides a shared library (and development files for it) starting from version 5.12. The whole Qt stack in Buster is 5.11. > I changed the .pro from: > > QT += ... virtualkeyboard ... > > to > > QTPLUGINS += qtvirtualkeyboardplugin > > and the qmake and Makefile were happy! I don't think that's the same thing: - "QT += virtualkeyboard" means that qmake will require the virtualkeyboard Qt library, using its headers when building and linking to it - "QTPLUGINS += qtvirtualkeyboardplugin" means that qmake will require the qtvirtualkeyboardplugin Qt plugin, which will be statically linked in your application In case the project actually uses the Qt virtualkeyboard library, your change will make qmake happy as you said, but then still won't make the project building. -- Pino Toscano
