How to copy cross-compiled Qt binaries from one computer to another

[Ketank16]

@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 followed the same as you said,when I am trying to run

./Sysroot-relativelinks.py sysroot

getting Output:

/usr/bin/env: 'python': No such file or directory

while getting this can I processed next?

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

@Pablo-J-Rogina

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....

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.
