With adding `-DPASTIX_WITH_MPI=ON ` in make\_pastix.sh, it seems OK.  
Then when compiling ccx\_2.19 with pastix, same error as [kmallick](https://calculix.discourse.group/u/kmallick) had.

Unfortunately, I didn’t get succeed when adding …/…/…/PaStiX/hwloc\_i8/lib/libhwloc.so to the end as Kmallick did.
