Qt 6

@SGaist Yeah. I still had to make other changes to get things to work but they were specific to us. I think it must have been the order in which I made the changes that made this seem necessary when they weren't

@Stokestack said in Is Ninja installed with Qt 6?:

I did find the following here:
"We recommend to use CMake's Ninja generator. This is also configure's default."

That's talking about building Qt, not building user projects.

Scroll down lower in the article: "Once you have installed Qt, you can use CMake or qmake to build your projects."

Ninja is not a requirement.

Not sure when configure is invoked, however.

configure is the script that starts the Qt build process.

There is no configure script for your own projects.

why didn't I get a complaint when opening it in the earlier Qt Creator, and also not when I opened it again in the current one?

I don't know.

Update us if you can reproduce the issue -- otherwise, there's not much else we can say or do.

@Stokestack said in QT SerialPort not found on QT Maintenance Tool:

Underneath that there is a 5.15.2 directory, but there's also a lot of important stuff that's right below "Qt" and not under the 5.15.2 subdirectory.

Look closely closely at my screenshot. That is my "Qt" folder.

It's the same as yours, but it has both "5.15.2" and "6.2.0".

And it seems like stuff that would clash with (or be overwritten by) a newer version:

Don't worry, the things in next to 5.15.2 will not get overwritten if you run MaintenanceTool.app.

(They will only get overwritten if you run the original installer, which you are not supposed to)

void QGridLayout::addWidget(QWidget *widget, int fromRow, int fromColumn, int rowSpan, int columnSpan, Qt::Alignment alignment = Qt::Alignment())

gridLayout->addWidget(graphicsView, 1, 0, 3, 1);

Thanks for that reply. That doesn't quite make sense though. Why can you create a single-level project and have Creator build you a CMakeLists file then?

With CMake becoming the native build system, I would expect Qt Creator to offer the same functionality it does today. That means (among other things) letting you create a "subdirs" project, which would add add_subdirectory to CMakeLists. Why doesn't it simply do that? What happens when QMake goes away?

I don't see how Qt can competitively proceed into the future if its IDE doesn't even let you manage your project. Furthermore, it's a huge missed opportunity to clarify CMake usage and expose its many functions in an orderly UI.

Apologies for false alarm....
It was crashing trying to set style sheet to a non existent plugin...
Issue resolved..
Thanks for the help :)

@laseranichris OK. You can report this in Qt bug tracker.

I am trying to add glew library into qt creator. But i have added the library. But It shows undefined reference while i add glewInit(); inside initializeGL() function. Could you please tell me the exact way to install glew in qt creator? it would be helpful for me.

@SGaist
removing self.parent = parent did not help. Problem still continues.

@VRonin
You can't get the connection, since Qt holds it. But there is a new interface added as of Qt 6.2 to get it, see:
See: https://code.qt.io/cgit/qt/qtbase.git/commit/?id=f5203eeada83bbe8e316a5188e24636af3e83b09

Then you should check with the brew folks to see how they are building Qt 6.

@QtQrustacean You may need to re-install Qt. I installed the default Qt for Desktop Applications from the installer (6.1.2), and had the same problem you did. By deleting that version of Qt and doing the Custom build, I was able to select Qt 6.1.2 and then add the Qt StateMachine package in the same area. So far, what I did is working.

Did you check the bug report system ?

@Jonas-Kvinge

Thank you Jonas ! I've spent days on this issue and now its finally fixed :-D

@nikhilsarma said in Installation error:

Wrong architecture, like @jsulm said. You want to install x86_64 packages, not i686 packages.

Uninstall these 32-bit packages and try again.

Can you post your configure invocation?
