Обсуждение: An issue installing an extension

I have 3 machines that _should_ be nearly idnetical. On 2 of them, i have
no issues installing an extension I copiled. On one I get the followign
error message:

icadb=# CREATE EXTENSION IF NOT EXISTS pg_libphonenumber;
ERROR:  could not load library
"/usr/lib/postgresql/11/lib/pg_libphonenumber.so": libphonenumber.so.7:
cannot open shared object file: No such file or directory
icadb=# ls -l /usr/lib/postgresql/11/lib/pg_libphonenumber.so


Yet, 

root@ica-db:/home/stan/BUILD/pg-libphonenumber-master# ls -l /usr/lib/postgresql/11/lib/pg_libphonenumber.so
-rwxr-xr-x 1 root root 182976 Oct 22 16:11 /usr/lib/postgresql/11/lib/pg_libphonenumber.so

This appears to be identical to the other machines where this works,

root@smokey:/home/stan/BUILD/pg-libphonenumber-master# logout
stan@smokey:~/BUILD/pg-libphonenumber-master$ ls -l /usr/lib/postgresql/11/lib/pg_libphonenumber.so
-rwxr-xr-x 1 root root 182976 Oct 22 09:47 /usr/lib/postgresql/11/lib/pg_libphonenumber.so


What else could be wrong?

This seems to be complaining about another library "libphonenumber.so.7"
that pg_libphonenumber.so depends on.  I think you forgot to install
that one on this machine.
