problem loading shared libraries

[mickey]

Hello,
under Centos I installed a software, Webots (robotic stuff). When I launch it I got this message:

./webots-bin
./webots-bin: error while loading shared libraries: libQt5WebSockets.so.5: cannot open shared object file: No such file or directory

./webots-bin
./webots-bin: error while loading shared libraries: libQt5WebSockets.so.5: cannot open shared object file: No such file or directory

To copy to clipboard, switch view to plain text mode 

Does anyone can tell me if there is something wrong with my installation of QT, and how get rid of it?

Regards.

Maybe your centos installation didn't get the package for QWebSockets installed yet?
Or does the program come with its own Qt libraries?

Cheers,

Sorry I'm a bit novice. What you said doesn't help me. However, it seems Webots comes with its own QT library:

Anyway, I don't know how to proceed....

Is webots-bin a script?
Does it set the LD_LIBRARY_PATH variable so that it points to the Qt libraries it ships with?
