    Hi, i am using Qt 4.8.7 . I downloaded it like this:
    sudo apt-get update
    sudo apt-get install qt4-dev-tools qt4-qtconfig qt4-demos
    sudo apt-get install qtcreator

    How can I add the library without switching to another version?

      Well, 4.8.7 did not have this module. You either have to build it yourself (and find sources that builds against Qt 4) or consider upgrading to at least Qt 5.

      The Qt 4 series has reached end of life quite a long time ago and should not be used to start new projects.

          As wrote earlier, since 6.2 so install the latest version and you should be good to go.

                      @J-Hilk in my windows computer it opens as you put it in the photo. But other device is ubuntu 18.04 . I downloaded it by typing the following command in the terminal.
                      sudo apt-get update
                      sudo apt-get install qt4-dev-tools qt4-qtconfig qt4-demos
                      sudo apt-get install qtcreator
                      when i download it like this it doesn't offer the option as you show. opens directly.
                      how can i do?

                        @SGaist already said no serial port is supplied with Qt4. He said if you really want to use Qt4 you would have to build it yourself (i.e. from sources, there won't be any apt ... which gets a pre-built binary.

                        You need first to decide whether you are going to use Qt4 or Qt6 (or even Qt5). You must use the same version on both Windows and Linux.

                            Not a great idea, up to you. You ask whether there is a "ready library" when we now have quoted to you 3 times

                            Well, 4.8.7 did not have this module. You either have to build it yourself (and find sources that builds against Qt 4) or consider upgrading to at least Qt 5.

                            What is unclear? It does not matter how many times you ask the same question the answer remains.

                                Then "i decide to use qt4 version on ubuntu" is not a good choice.
