    @RG97 PySide2 is just like any regular package in Arch Linux ARM

    @Pablo-J.-Rogina Have you tried installing PySide2 in arch linux arm. I installed arch linux in raspberry pi and have been trying to install the pyside2 using pacman manager but had no luck yet :(

      yes I did

      [alarm@alarmpi ~]$ uname -a
      Linux alarmpi 4.19.32-1-ARCH #1 SMP PREEMPT Thu Apr 4 00:12:02 UTC 2019 armv7l GNU/Linux
      
      [alarm@alarmpi ~]$ pacman -Qlq pyside2

      ...

      Are you talking about Arch Linux ARM, right?

      and have been trying to install the pyside2 using pacman manager but had no luck yet :(

      What happened? What error(s) did you get?

        @Pablo-J.-Rogina

        Are you talking about Arch Linux ARM, right?

        Yes, talking about Arch Linux ARM only.
        Okay so I was able to install it using pacman manager only

        [root@alarmpi alarm]# uname -a
        Linux alarmpi 4.19.46-1-ARCH #1 SMP PREEMPT Thu May 30 13:54:52 UTC 2019 armv7l GNU/Linux
        
        [root@alarmpi alarm]#  pacman -Qlq pyside2
        
        ...
        /usr/include/PySide2/QtCore/
        /usr/include/PySide2/QtCore/pyside2_qtcore_python.h
        ...
        
        

        But whenever I try to run the following snippet of code

        #!/usr/bin/python
        import sys
        from PySide2.QtWidgets import QApplication, QPushButton
        from PySide2.QtCore import Slot
        
        @Slot()
        def say_hello():
         print("Button clicked, Hello!")
        
        # Create the Qt Application
        app = QApplication(sys.argv)
        # Create a button, connect it and show it
        button = QPushButton("Click me")
        button.clicked.connect(say_hello)
        button.show()
        # Run the main Qt loop
        app.exec_()
        

        It is showing me this error

        [root@alarmpi alarm]# python test.py 
        Bus error (core dumped)
        
        

        Not able to get any clue regarding this.

          What version of of PySide2 do you have ?
          What version of Qt ?
          Did you try to run an equivalent C++ version of your application ?

            What version of Qt ?

            I just installed PySide2 in a freshly installed Arch Linux ARM running on raspberry pi. As far as I know, PySide runs long with Qt version >=5.11 .Correct me if am wrong, I don't need to build the Qt Core separately along with installing PySide2 in order to make it work ?

              No you don't have to build anything. But still the exact version will be nice to have.

              And please, try to build and run a dummy Qt widget application to see if it also fails.

                @SGaist
                PySide2 version is 5.12.13.

                [root@alarmpi alarm]# python3
                Python 3.7.3 (default, Mar 29 2019, 06:12:40) 
                [GCC 8.2.1 20181127] on linux
                Type "help", "copyright", "credits" or "license" for more information.
                >>> import PySide2
                >>> print(PySide2.__version__)
                5.12.3
                >>> 
                

                I tried running simple widget example test2.py as given below

                import sys
                from PySide2.QtWidgets import QApplication, QLabel
                
                app = QApplication(sys.argv)
                label = QLabel("Hello World!")
                label.show()
                app.exec_()
                
                

                It gave me the same error

                [root@alarmpi alarm]# python3 test2.py 
                Bus error (core dumped)

                  That's why I asked you to test the C++ equivalent of your test application. To see whether it's a PySide2 or a mare general issue.

                    @SGaist I built one c++ equivalent of a simple widget application for a raspberry pi kit and tried to run that. It gave me the same error i.e. Bus error(core dumped).
                    I use the same kit in Qt Creator to build Qml based C++ apps to be run on raspberry pi running raspbian stretch and those apps run smoothly.

                      Are you doing all of that directly on the Pi or are you cross-compiling ?

                          Then you have at least two versions of Qt on your target.

                          Where are they located ?

                            @SGaist I didn't get you exactly. I did a fresh installation of Arch Linux ARM and built PySide2 in it along with the required Qt packages. After doing all this I tried to run a simple PySide2 example and encountered the above error which I mentioned.

                                    @Pablo-J.-Rogina said in Not able to install PySide2 for raspberry pi:

                                    If you can use Arch Linux ARM as the OS for the RPi device, you may want to use already available packages for such platform. See ongoing discussion here.

                                    That's a great option. Also, the technical preview version (5.11) can be downloaded from new Raspbian Buster repository. My problem with these solutions is that I want to install PySide2 as a regular python package, so I can handle all dependencies of my application in the same way. That's the reason I'm using custom wheels. But, of course, Arch Linux ARM job looks amazing.
