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.

No. Install python in your host PC and repeat the step. Only when it succeeds you can go on.

Thankyou for the replay,

I installed python via

sudo apt-get install python3

when I am given the command like

python3

getting result Python 3.6.8

but after this,, executing the ./sysroot-relativelinks.py sysroot but getting the same result, No such file or directory....

[Asha]

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.
