Are they actually useful in practice? What do they do? > +QT5BASE_CONFIGURE_OPTS += $(if $(BR2_PACKAGE_QT5BASE_DEFAULT_QPA_MINIMAL),-qpa minimalb) is "minimalb" intended here, as opposed to "minimal"? Thanks! Thomas

That means that whenever a new platform is added (wayland, vnc, ...) we have to update the choice. And one could imagine a user implementing their own QPA plugin... So I would propose to make this a string, default to empty, and when it's empty don't pass the -qpa option. Help text could be something like Choose the default platform abstraction to use for graphical application. If this is empty, the default for your architecture will be used (usually this is eglfs). You can get a list of supported platform by running a Qt application with the option "-platform help" on your target. You can choose a different platform at runtime with the -platform option.

I have no opinion on that. If nobody has any arguments against, I am going to implement this idea.

Whithout this path, default platform is automaticaly set (generally set to "eglfs" as defined in qt5base/mkspecs/devices/common/linux_device_pre.conf:1). This choice is not always what the user would like. Thus, user have to manually appends "-platform <BACKEND>" to command line when running any qt5 application. This patch allows user to choose default platform explicitly.
