When I install the freefem++ on ubuntu 16.04, running the examples in hpddm and ffddm cannot load metis. The following is the error:

## 6 & load “metis” 7 & macro partitionerSeq(part, Th, size)metisdual(part, Th, size)// EOM macro partitionerPar(part, Th, comm, size)broadcast(processor(0, comm), part)// EOM ENDIFMACRO 6 : load “metis” load error : metis fail : dlerror : …/…/plugin/seq/metis.so: undefined symbol: METIS\_PartMeshNodal list prefix: ‘…/…/plugin/mpi/’ ‘’ ‘…/…/plugin/seq/’ list suffix : ‘’ , ‘.so’ current line = 6 mpirank 0 / 4 Load error : metis line number :6, metis current line = 6 mpirank 1 / 4 current line = 6 mpirank 3 / 4 current line = 6 mpirank 2 / 4 error Load error : metis line number :6, metis code = 2 mpirank: 0

## Primary job terminated normally, but 1 process returned a non-zero exit code… Per user-direction, the job has been aborted.

* * *

mpirun detected that one or more processes exited with non-zero status, thus causing  
the job to be terminated. The first process to do so was:

Process name: [[31387,1],1]  
Exit code: 2

what should I do ?
