Could somebody please explain step by step how to solver the problem of the missing lib that Nunos comented in this board?(c099935@ssxp6664f [116] 02:38 PM [cavity] FoamX
Starting NameServer with inet:ssxp6664f.sims.cranfield.ac.uk:1234 ...
nsd: error while loading shared libraries: libelf.so.0: cannot open shared object file: No such file or directory
)
for the understanding of somebody how has never used Linux?
With package should I install? from where? how? Can I do it if I am not administrator (root)?
I am using Linux CentOS.

Thank you very much for your help and best regards!!!!

Hello Marta

You just need to install the package that provides libelf library to your linux distribution.

In the case of CentOS, the package should be a RPM one, probably available from the repositories.

This should work (if libelf is the correct name):
su -c 'yum install libelf'

Good luck!
