    @ketank16 thank you very much for sharing your knowledge.
    I cannot test step by step since I don't have a BBB device, but it looks pretty much detailed and easy to follow.
    One picky addition if you will: I'd add the "location" (i.e. HOST or BBB) to every step so to be sure where the action/command needs to be run, something like:

    10. [HOST] Run following command in Qt directory:
    ...
    14. [BBB] (Open Beaglebone over SSH and follow this step)

          step by step,

          After./configure(step 10),the result is

          0_1568956288265_build (1).png

          Step 11,make -j4 The result is :

          0_1568956436569_make-j4.png

          Afer make installation I got the ~/BBB/sysroot/home/debian/Qt5ForBBB directory also,

            @asha said in How to copy cross-compiled Qt binaries from one computer to another:

            but I am not getting the qtcreator window

            What do you mean by that?
            There is no need to cross compile QtCreator for the device unless you want to use it on your device. Simply install QtCreator via installer on your Ubuntu machine and create a Kit there with your cross compiled Qt.

              @asha In your last screenshot, you can see udev errors. Apparently even after installing libudev on Beaglebone black and eventually copying it in sysroot doesn't solve the problem either. But a workaround is to make qmake look for udev in runtime rather than at compile time. The discussion and how-to is described in this thread here. You can follow it for current version of Qt as well. Let me know how the results come out for you.

                @asha Easiest way is make a file with that name on your computer and copy the contents from git file to your local file. Run sudo chmod a+rx Sysroot-relativelinks.py to make it executable and you're good to go.

                            Hi,

                            I seen where python3 is installed with the following command

                            which python3

                            the output is
                            /usr/bin/python3

                            so in sysroot-relativelinks.py file I edited the first line

                            #!/usr/bin/env python to #!/usr/bin/python3

                            After this again I executed the sysroot-relativelinks.py

                            now it is executed...what I did is it correct?...Thankyou...

                              @Asha You are supposed to have python2 (not python3) package. Ubuntu should automatically install python2 packages when you execute sudo apt install python.
                              Anyways for such a small script, I don't think its gonna make a difference but please remeber python package is python2 in Ubuntu repos and python3 is well python3 itself.

                                    @Asha You are supposed to have python2 (not python3) package. Ubuntu should automatically install python2 packages when you execute sudo apt install python.
                                    Anyways for such a small script, I don't think its gonna make a difference but please remeber python package is python2 in Ubuntu repos and python3 is well python3 itself.
