CC @troopa81 I think you have been waiting for this

[troopa81]

Yes! I was actually building it on my computer 😅 But is there PyQt 6.8.0? I see no release. Or is it built with a previous version of pyqt?

[m-kuhn]

It tries to build with a previous version, let's see if this succeeds

[m-kuhn]

@troopa81 builds are there (without pyqt, if required we could use dev versions)

[troopa81]

@m-kuhn I failed to use generated binaries. I just click the qgis.exe, the splashcreen appear and nothing. Is there anything else to do?

[nicogodet]

I confirm there is something wrong with this build

[m-kuhn]

Unsure if it's related to Qt 6.8 or missing bindings and I'm currently lacking the time to look deeper

I tried also another qt5 on another PR and it fails. There is maybe more...

[nicogodet]

Windows Qt6 build from master works on my side

[troopa81]

I'm building it on debug to check what happens
