[QGIS-Developer] Help compiling QGIS with Qt6 on Ubuntu 24.04/24.10

Tue Jan 7 09:15:32 PST 2025

Hello,

I've been also working on  this during a few times ago for a tutorial 
that I've never achieved: 
https://preview-pullrequest-1211--geotribu-preprod.netlify.app/articles/2024/2024-10-29_tester-qgis-4-futur-sig-open-source/#__code_1. 
The content is in French but QWT code is international ;).

Hope it helps.

Regards,
Julien
