    • Which Qt version do you intend use?
    • How did you install Qt? If you installed with apt, you may add the serialport module explicitely.

    @aha_1980 I am using Qt 5.6.1. I installed Qt creator with apt. What do you mean with "add serialport explicitely"?
    Thank you!

      Hi,

      What @aha_1980 asked was whether you also installed the Qt5 SerialPort package using apt.

        @aha_1980 told you need to install the packages individualy.

        sudo apt-get install libqt5serialport5
        sudo apt-get install libqt5serialport5-dev

          @KillerSmath I installed those packages via Software Center. Perhaps have I to uninstall them and re-install via apt-get?
          Could it be the reason for the "unknown module" error?

            Silly question: are you sure you are using Qt 5 and not Qt 4 for your project ?

              @SGaist Yes, the Help menu from Qt Creator reports:
              0_1528877526983_c9026808-fe20-4a8b-99f4-31be90b3f4e8-immagine.png
              In fact, I read that serialport module was not included in Qt4, but it seems I am using Qt5, this is the reason why I can't understand that build error..

                That's just the information about Qt Creator.

                You have to check the Kit you are using to build your application and which version of Qt it is using.

                  If nothing works, you can try to manage the packages from MaintenanceTool of QtCreator

                    1. <Qt Folder>/MaintenanceTool
                    1. Add or remove Components
                    1. Expand your Qt version
                    1. Expand Source Components
                    1. Select the Qt Source Package
                    1. Next, Install

                        In QtCreator go to Tools -> Options -> build & run and check your kits

                        In sidebar under the "Projects tab" you can select one of your installed kits:

                            from what one can see, it at least seems to be a version of Qt5, for more information press the "Manage kits" button

                              @J.Hilk The Manage Kit button shows the settings reported below, in which I can't find any information regarding the Qt version in use:
                              0_1528882243058_5fd714c7-c885-44b9-9911-43fbdc2ec394-immagine.png

                              If from terminal I write

                              $ qmake --version
                              

                              I obtain the following:

                              qmake: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/qmake': No such file or directory
                              

                              Is it relevant the "qt4" shown in that prompt?
                              Thanks.

                                well, there we have your problem

                                0_1528882573156_25bb3434-9c9d-43e1-91e3-d1d195bd5377-image.png

                                you have no QtLibary selected to your kit. Se if you can actually select a QtVersion from that dropdown menu. If you can't than you need to install an actual qt version.

                                I would recommend the online installer from the Webside.

                                  @J.Hilk Thanks, I added the version as shown below:
                                  0_1528884090398_f92cd759-ed4c-403b-9ff6-6b0378c19b45-immagine.png
                                  Now, since I should have Qt5, I added the serialport support in my .pro file, but the "unknow module" error still remains. I saw another thing that seems not so clear to me: I run Qt Creator from linux terminal, and when I open my project the terminal shows the following lines, marked in red, in which appears Qt4. Can this be related to the serialport module error?

                                  thank you again.

                                    @J.Hilk Thanks, I added the version as shown below:

                                    Now, since I should have Qt5, I added the serialport support in my .pro file, but the "unknow module" error still remains.

                                    @douglas Above you said you installed Qt 5.6, now you selected Qt 5.7.1
                                    Which Qt version do you really want to use and did you install QtSearialPort for Qt 5.7.1?

                                      @jsulm when I spoke about Qt 5.6 I was referring to the "About Qt Creator" window shown above. Now I selected Qt 5.7.1 as the version for my kit. But the serialport module isn't recognized yet. What I should do to correctly install QtSerialPort for my actual version?

                                        @douglas could it be possible that you start from scratch with a clean installation of Qt, ideally latest version 5.11? you may try in a virtual machine just in case.

                                          Is it me or are you trying to build your project for an embedded system ?
                                          I see that you are trying to use an arm compiler, did you cross-compile Qt for your device ?
