I’m thinking of writing a Qt app on my Mac. I also want to have builds for Windows and Unix, but I don’t have a handy Windows or Unix box.
I could use virutal ones, but that takes up a fair bit of room on my laptop. Also it’s a pain in the bum to have to spin them up and build the app manually. I’d really like the app to build itself automagically.
The simplest way might be to use GitHub Actions, as per this post (for Windows) and this post (for Unix), by Tom Rivoire.
