Re: Uncomfortable console warnings

[Jorge Carrión <shordi@xxxxxxxxx>]

The server's MySQL version is mysql-server-core-5.7 5.7.42-0ubuntu0.18...
and it's not something I can change, I'm afraid.

On the other hand, I feel tied to Qt5 because Qt6 has certain issues with
my system.

1. The gb.qt6.webkit package, which I used to develop an HTML editor,
doesn't exist in Qt6. This isn't a big problem, just switching to textEdit).

2. If I link the gb.qt6.Ext component, the program crashes at startup: Just
create a new project with the gb.form, gb.image, gb.qt6, and gb.qt6.Ext
components and try to run it: It generates a segmentation fault (11).

It seems I'm doomed to receive warnings :D

Best Regards
