On which OS are you working? Under Ubuntu you have to install the Qt serialport package.

I am working on ubuntu 14.04.I tried getting the source ( https://wiki.qt.io/Qt_Serial_Port#Getting_the_source_code ) but i always had the error :
fatal: unable to connect to code.qt.io:
code.qt.io[0: 54.77.201.214]: errno=Connection timed outIs there any other way to download them ?
EDIT : I downloaded it here :
https://qt.gitorious.org/qt/qtserialport/source/da396bc54b776da682ffdcd2aa61f504d607bc12:I tried to follow the qtcreator instruction from here :
https://wiki.qt.io/Qt_Serial_Port#Build_and_install_from_QtCreatorI added install argument to my make and then tried to rebuild the project but i have a issue :
/home/spi/Bureau/qtserialport/qt-qtserialport/src/serialport/qserialport.h:40: error: QtSerialPort/qserialportglobal.h: No such file or directory
I checked, the file is in the project and in the src folder.

Hi @wowy ,
I checked in the installation folder of qt5.2.1
- What is the full path to your installation folder?
- How did you install Qt 5.2.1?
If you installed it from the Ubuntu repositories, install Qt Serial Port from the Ubuntu Software Center (libqt5serialport5-dev).
I tried getting the source ( https://wiki.qt.io/Qt_Serial_Port#Getting_the_source_code )
Don't do that. There is a high risk that you will end up with multiple copies of the library in your computer, and you will have a hard time debugging if your program links to the wrong version.
Delete all the source code you downloaded and any binaries you built yourself. Use the official installers.

But if i use the install from the ubuntu software center it will only install it in the qt5 version i installed using the USC, right ?I use qt creator with a qt5 kit and a qt4 kit, i manually installed the qt4 version and i would need to use the serial port too with this version.

Hi @wowy,
Please answer the 2 questions in my previous post.

Right.
I use qt creator with a qt5 kit and a qt4 kit, i manually installed the qt4 version and i would need to use the serial port too with this version.
You only asked for Qt 5 in your original post, so I gave you a Qt 5 solution. Anyway, try that first; focus on getting it working for Qt 5 first. Worry about Qt 4 later.

I know this topic is very old and I'm sure everyone on here has figured out a solution, but I wanted to post my solution to this problem. I did the following things for linking QSerialPort to an application using the static build of Qt 5.11.2:
- Build Qt with the -static tag. (Specifically, my configure command was this: "./configure -static -prefix ../PathToQt/ -skip webengine -skip location -skip wayland". I skipped wayland and location because they had errors when compiled against std-c++11)
- Copy "libQt5SerialPort.a" from /PathToQt/qtserialport/lib/ to your project directory
- Copy "qserialport.h", "qserialport.h", and "qserialportinfo.h" from the /PathToQt/qtserialport/src/serialport to your project directory
- Remove "QT += serialport" from your .pro file if it's there.
- Change "#include <QSerialPort>" to "#include "qserialport.h" and "#include <QSerialPortInfo>" to "#include "qserialportinfo.h" where necessary
Hope this helps!

@MissingNo218 I forgot to add: You also have to add "LIBS += libQt5SerialPort.a" to your .pro file
