I try to deploy a simple hello world GUI on Qt on linux I first compile the program on QTcreator and I collect all the needed library with that shell script: https://h3manth.com/content/copying-shared-library-dependencies
Then I get that error:
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
I found on stackoverflow "Failed to load platform plugin "xcb" " while launching qt5 app on linux without qt installed that the trouble should come from a lack of library.
So I take all the so file in my /Qt/5.7/gcc_64 and I put all these on my other computer. I do a export LD_LIBRARY_PATH to the folder where the library are located but I still get that error.
