adding new class in Qt Creator

[herrgross]

Hi everyone,
as quite a newbee I feel especially stupid now:
wanting to work with QSerialPort I find that Qt Creator does not know it. When I try to #include, I get "file not found".
Searching the web did not lead me to a solution.
Can anybody help me on how to include that module into my setup?
Thank you
Michael

yo need to include the package to the project

to use the #include <QSerialPort>

if you are using CMake:
you need to add the:

find_package(Qt6 REQUIRED COMPONENTS SerialPort)
target_link_libraries(mytarget PRIVATE Qt6::SerialPort)

if you are using qmake
you need to add

qmake:	QT += serialport

you can see what you need in the initial table of every class description

https://doc.qt.io/qt-6/qserialport.html

@Sebastiano-Zamberlan I am using QMake, but adding serialport port in the .pro file like this:

QT       += core gui serialport

gives me "Project ERROR: Unknown module"

Project ERROR: Unknown module"

and the unknown module is serialport?
How did you install Qt?

@herrgross

check with Qt Maintenance tool if you add the library "Serial Port" of your current Qt release, you find it under "additional libraries"

[herrgross]

@jsulm yes, unknown module serialport.
What do you mean by "how did you install"?
I'm on a Mac, installed from the Qt webpage

I mean exactly what I asked.
There are different ways to install Qt.
If you installed using the online installer then follow what @Sebastiano-Zamberlan suggested.

ok, thank you, I found it... strange, that there's no hint in the helpfiles how to do such a simple thing.....
