Installing Qt on RasspeyPi?

Mucip

Hi,
I want to install Qt6 from "qt-online-installer-linux-arm64-4.9.0.run". I installed but could not run QtCreator?

I got below error message unfortunatelly.

The Qt 6.9 that comes with the online installer is built for a Raspberry PI 5 running Ubuntu 24.04 so if your OS is older than that, it's time to upgrade.

Mucip

Hi,
Yes, I use RP-4 now unfortunately. :(
My Debian version is 12.10
By the way, I could not find apt install qt5-default either.
This is very bad.

You could try the Qt 6.4.2 Bookworm native packages, say start with:
qt6-base-dev
qt6-tools-dev
...
They are listed here:
https://packages.debian.org/source/bookworm/qt6-base

Mucip

Hi,
I installed both but I can not see QtCreator in the Programing menu still?!
By the way there isn't qt6-base either?!

Hi,

Qt Creator is an independent project and has dedicated packages from your distribution.

Mucip

Hi,
well, How can I use QtCreator in RP-4 than?
I want to create and run C++ programs in Qt?

Regards,
Mucip:)

SGaist

Well, install Qt Creator with the package manager from your distribution. Since it's Debian: apt-get install qtcreator.

Mucip

Hi,
I am installing now.

Mucip

Hi,
I used many times QT in RP. But It was not difficult as now unfortunately.
I installed QtCreator and open. I created very basic project but could not run even?!
Message:
:-1: error: Cannot run compiler 'clang++'. Output:

SGaist

Did you install the build-essential package ?

Mucip

Hi,
sudo apt install build-essential

Already installed...

Mucip)

SGaist

Then since you seem to want to use clang for your build: install it as well,

Mucip

Hi,
I could create program finally... :)

But in any case I've got below messages;
22:11:28: Starting /home/milbuga/Documents/Qt/build-untitled-Desktop-Debug/untitled...
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
QStandardPaths: wrong permissions on runtime directory /run/user/1000, 0770 instead of 0700

Start your application with the QT_DEBUG_PLUGINS environment variable set to 1 to see exactly what is happening.

Mucip

Hi,
Should I put
QT_DEBUG_PLUGINS = 1

in pro file?

Regards,
Mucip:)

SGaist

No, it's an environnement variable.
In Qt Creator, go to the Run part of the Project panel and there you can add it to the list of environment variables.

Mucip

Hi,
In this case there is many more errors. :)
I remove line again.

Mucip:)

Mucip

Hi,
As mentioned here below lines are solved my problem without adding environment variable.
sudo apt install libxcb-xinerama0
sudo apt install qt6-wayland
sudo apt install libxcb-xinerama0-dev
sudo apt install qt6-wayland-dev
