How to include <QSerialPort> correctly?

BurSer

I'm trying to include QSerialPort in a project. In the .pro file I've written this:

QT       += core gui network
greaterThan(QT_MAJOR_VERSION, 4) {
    QT += widgets serialport
}
else {
    CONFIG += serialport
}
CONFIG += c++11
...

and so on.

After trying to build (or clean-qmake-rebuild) I get the message "Project ERROR: Unknown module(s) in QT: serialport".

I've also tried to find the file QSerialPort or QtSerialPort in the folder with all the Qt and there's no such file.

System: Windows 10, Qt Creator 4.14.0 based on Qt 5.15.2, MinGW... (don't remember the version but I've downloaded it today).

Hi
Thats a bit odd as its normally just
QT += serialport
As far as I know, that module is not optional and always installed.

Are the examples there ?

INFO: Qt Creator is an IDE, it version is NOT relevant.

Which Qt Kit do you use to build your project (cf. Tools/Options/Kits)?

Edit:
~~CONFIG += serialport does not make sense to me, it should be QT += serialport~~
My bad CONFIG += serialport is for Qt 4.x!!

AFAIK, QSerialPort is not available with Qt 6.0, you have to use Qt 5.xx or wait until it is ported to Qt 6.x

Good catch !

@KroMignon Thanks! The problem was in Qt 6. After changing it to the last subversion of Qt 5 everything has been compiled. (At least, Qt Creator isn't angry about the .pro file.)
