Deploy Qt opencv how do it
-
i search several time in here and all web but i dont understand or i didnt make or not enough knowlodge.
i am using
Ubuntu Ubuntu 22.04.2 LTS
opencv 4.7.0
Qt Creator Qt Creator 9.0.1 Based on Qt 6.4.0 (GCC 10.3.1 20210422 (Red Hat 10.3.1-1), x86_64)
i want that, make a exacutable file on another linux system, Please explain how do it.
i try with linuxdeployqt-continuous-x86_64.AppImagethanks for advance

@asisisyah Have you looked at this?
@Abderrahmene_Rayene
yes ofcourse, developers says you must use old versions of Linux like this ubuntu 16.0. , its not to be such as hard . i want deploy with linked Qt library and opencv library ... than execute it on another linux computer or run on embeded linux..
is there lesson or tuttorial or anythig. -

@Abderrahmene_Rayene's link told you to pass-unsupported-allow-new-glibcto yourlinuxdeployqt. How did that go when you tried it? -

That is what you said before. Are you now saying you have got past that via the
-unsupported-allow-new-glibcand this is a new error? It helps if you explain....OK, I have not used
linuxdeployqtbefore, but this looks likelibQt6Gui.so.6, a Qt shared library file, cannot be found. So did that go into the the image created bylinuxdeployqt? 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'slibopencv_highgui.so.407when a moment ago you said it'slibQt6Gui.so.6. It's really hard to follow what you are claiming....In any case, the whole point of
linuxdeployqtis 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, -

thank you for interesting,@asisisyah said in Deploy Qt opencv how do it:

of course, because you did not properly deploy your app for your target.
@asisisyah said in Deploy Qt opencv how do it:
libQt6Gui.so.6 -> this error means , if i run linuxdeployqt on my computer in my terminal show error.
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
linuxdeployqtworking properly, then it's much easier to help you with deploying opencv into your app. -

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 libsi tried just now that

You're making progress, so that's good.
Good luck!
