MaintenanceTool

[SPlatten]

I want to update the tools I am using, presently I am building with 5.15.2, I want to update the tools to 5.15.16 as I want to use the Anchor Layout, the example I've seen online is using 5.15.16, however when I launch the MaintenanceTool, I see lots of Qt 6.. versions, but only Qt 5.15.2 and before that, nothing after the Qt 5.15.2.

What do I need to do ?

I'm working on iMAC:

macOS Monterey
Version 12.7.2
iMac (Retina 5K, 27-inch, Late 2015)
Processor 4 GHz Quad-Core Intel Core i7
Memory 16 GB 1867 MHz DDR3
Graphics AMD Radeon R9 M395X 4 GB

About Qt Maintenance Tool:

Based on Qt 5.15.11
Built on Aug 23 2023
From revision 0e9da21a36ff1d2ae9830654fc59eb6b872242

Is it a big jump to go to Qt 6.6.1. ?

@SPlatten said in MaintenanceTool:

What do I need to do ?

Since open source people are supposed to switch to Qt6 Qt-company does not provide pre compiled Qt5 versions past 5.15.2

Therefore you have 2 options:

1. Get a comercial licence and use the maintenancetool to get the latest 5.15.16 precompiled to download
2. Build Qt yourself. But only the slightly out of date variant of Qt5.15.12 since the open source release is delayed by at least a year

@J-Hilk , thank you, I'm presently installing 6.6.1, will see what issues I face.

[J.Hilk]

@SPlatten from my personal experience porting projects from Qt5 to Qt6 I'm afraid the answer will be "All kinds of issues and lots of them " 🙈

Best of luck anyway!

@J-Hilk , are they're any preprocessors I can use to conditionally include certain headers when building for 5.15.2 or 6.6.1 ?

For example just building it now and with 6.6.1 it complains about:

#include <QtWidgets/QAction>

I would prefer to wrap this line so it is used when building for 5.15.2 but something else when 6.6.1:

#include <QAction>

Edit:

#if QT_VERSION == QT_VERSION_CHECK(5, 15, 2)
        #include <QtWidgets/QAction>
#elif QT_VERSION == QT_VERSION_CHECK(6, 6, 1)
        #include <QAction>
#endif

@SPlatten in Qt 5.15.2, you can do

 #include <QAction>

as well. QtWidgets is not needed.
