Problems when running the case of I4DVAR

[lizengocean09]

Hi, everyone. When I ran the case of I4dVAR with the command mpirun -np 4 ./oceanG ocean_wc13.in. I got the following errors:
/usr/local/netcdf/bin/hydra_pmi_proxy: error while loading shared libraries: libcr.so.0: cannot open shared object file: No such file or directory
HYD_pmcd_pmiserv_proxy_init_cb (pm/pmiserv/pmiserv_cb.c:448): assert (!closed) failed
HYDT_dmxu_poll_wait_for_event (tools/demux/demux_poll.c:77): callback returned error status
HYD_pmci_wait_for_completion (pm/pmiserv/pmiserv_pmci.c:196): error waiting for event
main (ui/mpich/mpiexec.c:336): process manager error waiting for completion.

Any help would be appreciated.
