Hi Fabrice, I'm on Windows 10 64-bit, using the official pre-built version of Qt 5.12.0 for MSVC 2017 32-bit. I can confirm that qDebug() and co are working as usual for me, so I don't think there is anything wrong with Qt 5.12.0 itself. So, let's figure out why it's not working on your machine. First, can you provide details on how you installed this version of Qt 5.12.0? Second, launch SysInternals DebugView (https://docs.microsoft.com/en-us/sysinternals/downloads/debugview ) before you launch Qt Creator. Do your qDebug() messages appear in DebugView?
