Linux doesn't see the library.

How did you install Qt? Did you forget to install the QtBluetooth development package?

This way

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install qt5-default
sudo apt-get install qtcreator
sudo apt-get install qtdeclarative5-dev

Is it separate installation for the Bluetooth package?

Maybe - you already installed a separate one for qtdeclarative5 so why shouldn't there be one for qtbluetooth5?

OK. I installed libqt5bluetooth5. What should I add in a *.pro file?
QT += bluetooth - gives an error

libqt5bluetooth5-dev

I get - Unable to locate package libqt5bluetooth5-dev

Please think before writing - when the qtdeclarative5 dev package is named qtdeclarative5-dev - how the qt5bluetooth5 dev package is maybe named?

I love quizzes, especially - find the pattern.

qtbluetooth5-dev
qtbluetooth-dev
qt5bluetooth-dev

none is working.

The winner is - libbluetooth-dev

@jenya7 You did not say what Linux distribution you use.
On Ubuntu 20.04 there is indeen no dev package for QtBluetooth module.
What error do you get when you add bluetooth to your pro file?

It's Raspbian Linux.
It reports - libbluetooth is installed but on QT += bluetooth I get

Project ERROR: Unknown module(s) in QT: bluetooth

@jenya7 I think you need to install qtconnectivity5-dev package.

Nice! That's it!

[Christian Ehrlicher]

Strange packaging... I would expect a little bit more consistency here. Mhhh..
Is there at least an overview somewhere for e.g. raspbian to see in which package a file can be found?

[jsulm]

@Christian-Ehrlicher One can use apt-file to search for packages providing specified file.

[SGaist]

@Christian-Ehrlicher because QtBluetooth part of the QtConnectivity module along with nfc therefore the package name used.

[Christian Ehrlicher]

@SGaist Thx for the clarification :)
