[QGIS-Developer] Qt6: qgsspatialindex.sip: line 148: column 5: 'QgsSpatialIndex::intersects' has an unsupported return type

[Richard Duivenvoorde]

FYI on Debian Sid, I use a commit of Nyall to which he pointed earlier:

https://github.com/nyalldawson/QGIS/commit/c9b8c74d8abbc61f373dafbe94c35f2b8e9fe41d

I do have some Python issues with the dbmanager then though, which I then remove from the build.
The rest is working and I was able to make a plugin work for Qt6.

Not sure if all this 'magic' (to me) is still needed.

Regards,

Richard
