Compile PyQt5/6 with Python3

mpham · 03-13-2023, 05:29 AM

Hello, sorry if it has been asked before. I've tried to search but no luck.
I'm trying to write an app with python + qt, currently it's using python2 + pyqt4 which are very old. Anyone please could help me to compile pyqt5/6 with python3? I've tried also the koxtoolchain but always gave me error compiling qt5.

Thanks

Fair warning: Here be dragons. You're in for a world of hurt.

That said, Qt5 *has* successfully been built in the past, but I haven't looked at it in a couple of years, and things haven't really gotten easier with Qt6, from what I heard...

I was *not* masochistic enough to even attempt to deal with PyQt/PySide, though; which promises to send you to yet another deeper level of hell, as it's already hilariously unfun on *native* builds...

Also, keep in mind that if you want to target non-X devices (i.e., FW < 5), you'll need to write a custom QPA (and I'm not even sure if Qt6 still has a linuxfb backend to help with that...).

The recap of this extremely painful endeavor would be https://github.com/pgaskin/NickelTC

It's for Kobo, and as such targets an old Qt5 version, but my original script *does* support a more recent (but still old nowadays) LTS release. I did *zero* runtime checking on that, though; it was just used as a sanity check to ensure this was actually even remotely doable without going completely mad.

I'll reiterate that unless embedded systems stuff is your actual job, and/or you have a mountain of time and sanity to throw at the problem, I would run away screaming and opt for a different approach altogether.

As was mentioned in another recent x-compile thread, going the buildroot way *might* ease some of the pain; as it appears to have packages for pyqt5
