I've the followings and so many others alike:

--------
mpicc
mpif77
mpif77.lam
mpif77.mpich
mpif77.mpich-mpd
mpif77.mpich-shmem
mpif77.openmpi
mpif90.openmpi
--------

According your advices, should I configure pwscf like this:

./configure FC=mpicc

or 

./configure FC=mpif90.openmpi

In fact, in this way, I will meet the same error messages.

I've mpif.h in many locations on my system, such as, /usr/include, 
/usr/lib/mpich/include/, but the *locate mpif.h* command give me 
nothing, why?

P.S.  I have poor knowledge about mpi.  In my case, my 
machine is just a standalone computer, not a member of a cluster, should 
I use mpi or not?

Thanks in advance.
