Installation QtSerialport

bsuarez

Thank you for your reply.

I installed QT5 using QtCreator package on ubuntu and I have no trace of QtSerialPort include files in the /usr/include/qt5 !

The version of QtCreator package: 3.0.1-0ubuntu4
Qt Creator 3.0.1
Based on Qt 5.2.1 (GCC 4.8.2, 32 bit)

What is the problem?
thank you

Qt Creator is only the IDE. You need to install Qt development libraries.

The recommended way to get the libraries is from the official website: http://www.qt.io/download-open-source/

However, you can get packages from the Ubuntu Software Center too if you want. Be aware that there are many separate packages, such as libqt5serialport5-dev.

Hi,

I'm want to use the QSerialPort Library for QT 5.7. But I cant find any downloads and it doesn't seem to be preinstalled. I'm working on a win pc.
Can you tell me where I can download the QSerialPort library?
Thanks!

Hi,

It comes with your installation of Qt

Hi,

but when I try #include <QSerialPort> then I get an error "No such file or directory." I addes QT += serialport.
On the web I found something like #include <QtSerialPort/QtSerialPort>. But is it the same library? And does it have an info library too?
Sorry for beeing such a newbie :D

@Smileede How did you install Qt?
And what do you mean by "info library"?

Smileede

Thanks for your response!
I did the installation via an online installer. Or what do you mean?
The "info library" is the QSerialPortInfo library. Sorry for beeing unexact!

@Smileede Can you check whether you have the QtSerial header files? See in Qt/5.7/mingw53_32/include/QtSerialPort. Replace mingw53_32 with what ever Qt version you installed. Maybe something went wrong during installation.

Yes, it is there! Ahh, now I got it! If I type #include <QTSerialPort/qseriaport.h> it does work :)
But I can also include QTSerialPort/QtSerialPort. Is there any difference between QtSerialPort and QSerialPort?

Thank you for your help!

There's always one basic that should be done: did you re-run qmake after you added QT += serialport to your .pro file ?
