The readme states Qt 5.2 or newer is required.
Where did you get Qt4 from and why?

[barracuda156]

@jbruechert Thank you for responding.

The following line implies that Qt4 is supposed to be supported:

Baka-MPlayer/src/Baka-MPlayer.pro

Line 10 in 4265eba

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

Otherwise it makes no sense to have it there.
Likely this was not tested for ages though, understandably.

Why – because Qt5+ is broken on some non-mainstream platforms, while Qt4 works perfectly fine.

[jbruechert]

I suspect updating the .pro file was just missed when introducing Qt 5 specific code.

I'm not a contributor here, but I do lots of Qt based stuff, and I'd say still supporting Qt 4 right now is probably very rare. Most projects will probably be looking into dropping support for Qt 5 right now if they haven't already. Probably time is better spent on adding and maintaining support for your platform in Qt 6 rather then getting things to run on Qt 4. For example QML has changed pretty fundamentally, so having one project using it work on Qt 4 - Qt 6 is not feasable.

[barracuda156]

@jbruechert I do agree that fixing Qt6 is better in principle, the problem for my case is that Cocoa is hopelessly broken for any macOS besides the very latest ones (something happened with advent of Qt5: Qt4 was very portable, but with Qt5 support for a lot of platforms went out of the window, and the code was not simply unmaintained, but deliberately broken; so for Cocoa it is pointless to try beyond very early 5.x, which are not much better than Qt4 anyway), while X11 is broken for all macOS altogether, including the latest ones. So the backend which is the most portable, normally, is designed here to be defunct. (I could fix the build of qt6-qtbase on Sonoma, and I have no idea how much more it gonna take to fix it for earlier versions. But qtbase on its own is useless, and at least several more libraries are needed. I do not know whether it is worth, even if feasible, to be honest. If I knew for sure that the code will actually work at least, I would be more motivated. However, the whole of Qt codebase is a pile of bugs, which are hard to track down and perhaps harder to fix. Perhaps the situation could be substantially better on Linux, but that doesn’t make life easier for macOS.)
If you happen to know how to switch Qt6 to build against X11 on macOS without hacking hundreds of files, I will try that. It should be a matter of configure switch – but it is not.
