    @asisisyah said in Deploy Qt opencv how do it:

    it said that, your system is too new

    That is what you said before. Are you now saying you have got past that via the -unsupported-allow-new-glibc and this is a new error? It helps if you explain....

    OK, I have not used linuxdeployqt before, but this looks like libQt6Gui.so.6, a Qt shared library file, cannot be found. So did that go into the the image created by linuxdeployqt? Did it get extracted? If so to where?

    if i tried with -unsupported-allow-new-glibc it show these error.
    its not extract anywhere.
    my app its working my computer with Qt release run and Qt make new folder called Release , its working may app in folder or anywhere in my computer Desktop ,Document or Download folder as single file no problem but when its work on another computer, my app says "error while loading shared libraries: libopencv_highgui.so.407"
    may be i can should add theese library file in other computer , but how?
    may be add all needed library add in myApp Static or Dinamik, i

      Now you say it's libopencv_highgui.so.407 when a moment ago you said it's libQt6Gui.so.6. It's really hard to follow what you are claiming....

      In any case, the whole point of linuxdeployqt is to bundle all the libraries you need for your application and copy them onto target system. You need to find out what it is bundling/why it isn't doing so.

        libopencv_highgui.so.407 -> this error means if i run myApp on other linux computer. other computer says that error message.

        libQt6Gui.so.6 -> this error means , if i run linuxdeployqt on my computer in my terminal show error.

        at the point , all error message for linking , i cant deploy with linking with QT or linuxdeploy, how is solve
        thank you for interesting,

          of course, because you did not properly deploy your app for your target.

          How about you just focus just on this error? solving it would solve your first issue.

          You can answer my question if you'd like to troubleshoot this error further.

          Once you get linuxdeployqt working properly, then it's much easier to help you with deploying opencv into your app.

              It seems so, OP copied everything on the terminal and pasted here unformatted.

              @asisisyah what do you get if you use this command:

              ldd libQt6Gui.so.6

                  it seems like your ldd cannot find Qt shared libraries because they are not in a standard path, it needs to be configured to find them, it might not be a linuxdeployqt issue.

                  qmakePath 3= ""

                  the above does not look right to me, so trying the below might help:

                  linuxdeployqt <your app> -qmake=/path/to/Qt/your Qt version/gcc_64/bin/qmake

                  this might be of some use as well : Qt deployment can't finde my libs but ldd can

                    this command is work. al Qt libraries came in folder under the lib folder. YES.
                    qt library is okey i think,
                    so how i get opencv libs

                    i tried just now that
                    sudo ./linuxdeployqt-continuous-x86_64.AppImage /home/yep/Desktop/deploy3/deploy12 -bundle-non-qt-libs -unsupported-allow-new-glibc

                    its work all opencv libs came in same lib folder.

                    than i tried other computer i take this error message
                    libQt6Widgets.so.6: undefined symbol: _ZTIN4QCss13StyleSelectorE, version Qt_6_PRIVATE_API

                      @asisisyah every solution I mentioned so far is just me using uncle google, try to google that error, try the solutions you find, and let us know when all of them do not work and why they did not work (error and so on).

                      You're making progress, so that's good.

                      Good luck!
