    @Digvijay said in QSerialPort Library for Qt creator 4.8 on Debian 9:

    @SGaist I also do not want to use Qt 4.8. But my linux is 32 bit so i can not install Qt 5.8 which requires 64 bit linux.

    No it doesn't, it's just that the pre-built package is not provided any more for 32 bit.

    Debian stable comes with 5.7 for all its support architectures which includes 32bit. If you need a more recent version of Qt, you can build it.

      It is impossible. Please read that link more closely.

      @kuzulis I again tried installing but it is not working. I have attached the terminal output.

        Hi @Digvijay,

        Why do you git clone two times? After the first clone, you switched to the correct branch and the build would have worked. Also, the build directory should be outside, parallel to the sources.

        So, once again the needed steps:

        $ git clone git://code.qt.io/qt/qtserialport.git
        $ cd qtserialport
        $ git checkout qt4-dev
        $ cd ..
        $ mkdir qtserialport-build
        $ cd qtserialport-build
        $ qmake ../qtserialport/qtserialport.pro
        $ make
        

        I'm also not sure if all the PATH manipulations are needed - I guess not.

        Regards

        Qt has to stay free or it will die.

          Hi @aha_1980
          Thanks for the reply. Now i can build the library but it is still not visible to Qt creator. When i add CONFIG += serialport to .pro file it is giving the error as follows
          Project MESSAGE: Warning: unknown QT: serialport
          So still what is going wrong??
          Also can you please tell me how to install Qt 5.8 on 32 bit debian 9?? Because i do not want change my windows based GUI every time. I want directly compile project. I do not want to work in lnux environment as i am not familiar with it.

          Regards,
          Digvijay

            @Digvijay Why do you build Qt by yourself?
            As @SGaist pointed out Debian stable already provides Qt 5.7 (including 32bit).

              Hi @Digvijay,

              I guess you need to call sudo make install as last step.

              But as others said, why don't you install the Qt version supplied by your distribution?

              Because i do not want change my windows based GUI every time. I want directly compile project.

              Sorry, I don't understand what you mean by this.

                Yes i know that Qt 5.7 is available. But i do not know how to install it. Do i need to uninstall the Qt 4.8?? And how to install it on linux??
                And one important thing is i have only one day of experience in linux. So i am sorry if i am asking silly questions.

                  Then before starting to develop you should first get to know the distribution you are using. Start by looking up the Debian package manager: apt. Depending on your desktop environment you might even have a GUI on top of it.

                  No you don't need to uninstall anything, Qt 4 and 5 can co-exist without any problem.

                    @Digvijay To add to @SGaist on Ubuntu (and most probably on Debian) there as a GUI tool to install/uninstall packages: Synaptic.
                    Install it using: apt install synaptic

                        Yeah, thats what we do also. Where is your problem with that?

                        Regarding QtSerialPort, you have several possible solutions:

                        • use Qt5 as provided by your Linux distribution
                        • use the Qt5 online installer for 32 bit Linux (I think the last version is Qt 5.5.1)
                        • compile QtSerialPort for Qt4 yourself
                        • use a Linux distribution that has a newer Qt5
                        • compile Qt5 yourself

                        If you are not limited to 32 Bit Linux, you can install the newest Qt also via the 64 bit online installer.

                        Regards

                          Yeah, thats what we do also. Where is your problem with that?

                          Regarding QtSerialPort, you have several possible solutions:

                          • use Qt5 as provided by your Linux distribution
                          • use the Qt5 online installer for 32 bit Linux (I think the last version is Qt 5.5.1)
                          • compile QtSerialPort for Qt4 yourself
                          • use a Linux distribution that has a newer Qt5
                          • compile Qt5 yourself

                          If you are not limited to 32 Bit Linux, you can install the newest Qt also via the 64 bit online installer.

                          Regards

                              @SGaist with the library the mistake i was doing is that, i was cloning it two times. For installation of Qt 5 , i had to download right version of Qt which is compatible with my linux then installation part was easy.
