/usr/local/sbin/oxenstored: error while loading shared libraries: libxenctrl.so.4.14: cannot open shared object file: No such file or directory on Ubuntu 20.10

Hello.

I've just compiled xen 4.14 from source on ubuntu 20.10. The compilation didn't produce errors. But then,when I ran this command :

root@zio-z390aoruspro:/etc/xen# sudo /etc/init.d/xencommons start

this is what happened :

Starting /usr/local/sbin/oxenstored.../usr/local/sbin/oxenstored: error while loading shared libraries: libxenctrl.so.4.14: cannot open shared object file: No such file or directory

I don't know how to fix it. After several tries,I asked what to do,before to damage the system.
