This is a port of the QtBase module of the Qt software development framework version 5 to the OS/2 operating system (and its derivants). This port is carefully crafted and maintained by bww bitwise works GmbH (also referred as bitwiseworks).
The current version of the port implements all major parts of the QtBase module and is suitable to compile and run a large amount of Qt 5 applications on OS/2.
An impressive effort, but I do have to wonder – what is the benefit of running OS/2 when all of the applications you’re using are better served running on, I don’t know, KDE or Windows? Doesn’t it make more sense to direct effort towards native applications?
Are you serious? Writing new applications takes much, much more resources than porting existing ones. The only desktop platforms that have enough manpower to maintain their own native ecosystems are Windows, macOS and the unix-likes. OS/2 is definitely not among them.
