    Hi,

    i want to deploy my app on other Linux machine without installing Qt on it. I have followed linuxdeployqt but i couldn't make it work.
    Processor type: aarch64
    Qt version: 5.9.5
    OS: GNU/Linux

    Could you please provide me some easy steps?

    Thanks in advance.

        Looks like you're trying to execute x86_64 binary on ARM or x86 which can't work. On which machine (PC, target device,...) do you execute it?

        Also, did you made linuxdeployqt-6-x86_64.AppImage executable?

            @sharath Please be more precise. You downloaded linuxdeployqt-6-x86_64.AppImage from https://github.com/probonopd/linuxdeployqt/releases, is this correct?
            I already asked, but once more:

            • Did you mark it as executable?
            • Do you execute it on an x86_64 machine

            "Can u please tell me how to create and get appImage of linuxdeployqt for ARM?" - as described here https://github.com/probonopd/linuxdeployqt

            Or here https://doc.qt.io/qt-5/linux-deployment.html "Creating the Application Package".

                Well, since it's x86_64 binary it will not work on anything else.
                Do it on your PC. And then follow the instructions to deploy.

                One question: do you do cross compilation or do you build/deploy directly on your device?

                    Then you need to compile linuxdeployqt on that device, too. Building instructions are in a file called BUILDING https://github.com/probonopd/linuxdeployqt/blob/master/BUILDING.md

                          There's an alternative that's supposed to work on newer Linux systems:

                              Thanks @sierdzio, it has worked and created all dependent libraries.

                              But when i take this app and run this in other machine i get below error

                              ./AppRun: error while loading shared libraries: libGLdispatch.so.0: cannot open shared object file: No such file or directory

                                Do you run linuxdeployqt with -appimage flag? Try running it twice, it sometimes helps.

                                Does your other machine have OpenGL libraries installed? Does it support OpenGL at all?

                                  @sierdzio said in Deploying Qt Application on Linux:

                                  Do you run linuxdeployqt with -appimage flag? Try running it twice, it sometimes helps.
                                  Does your other machine have OpenGL libraries installed? Does it support OpenGL at all?

                                  i ran linuxdeployqt with -appimage many times and also openGL is installed on my target system.

                                  i'm getting same issue

                                    OK then. Run with -verbose=3 and look at the output - perhaps there is some warning there that is important for you in this case.

                                    You can try running deploy first without appimage flag, then copy the OpenGL library manually into the package, then run linuxdeployqt again with -appimage.

                                    Lastly, maybe -extra-plugins= flag can be used to force linuxdeployqt to deploy that library.

                                        Does the AppImage run correctly when you launch it on the original machine (same where you compile and run linuxdeployqt on)?

                                        I don't have any further ideas.

                                          i think this is the issue i guess.
