QT Creator on raspberry pi4 (4GB RAM).

[pirates21]

I would like to install QT Creator on raspberry pi4 (4GB RAM). I don't want to do kross-compiler . How to do it with all possible modules such as qtwebenginewidgets, charts, multimedia widgets etc. Do you have any instructions?
Best regards,
Sebastian

Hi
Unless you can find a Qt version already compiled for pi4
then you will have to make a Qt version that
runs on it.
I think the debian stretch comes with older version.
There are many tutorial on the net building Qt for Pi boards

https://www.tal.org/tutorials/building-qt-512-raspberry-pi

Pay attention to the eglfs X11 and/or Wayland options.

You most likely want to use X11 since it sounds like you have a
Desktop linux running on it.

However, be prepared to use time on it. Its not super trivial.

Also, it seems in Buster
the https://www.raspberrypi.org/forums/viewtopic.php?t=244984
it comes with Qt 5.11
so maybe thats enough for you ?

you can download it from packages

sudo apt-get install qml-module* (what ever module you need)
sudo apt-get install qt5-declarative qtcreator qt5-default or qt5base*

(i do not know exact packages names, just pres tab to check if it is available)

on raspberry 3 it was necessary to activate OpenGL EGLFS to use qml but since raspberry 4 can use opengl es 3.0 you do not need to compile on your own to use qml

Thank you for your answers, especially David_001. Your suggestions allowed me to start stream from camera via QtMultimedia.
