Mahmood, mpi_siesta is a siesta library, not an Open MPI library.
fwiw, you might want to try again from scratch with MPI_INTERFACE=libmpi_f90.a DEFS_MPI=-DMPI in your arch.make i do not think libmpi_f90.a is related to an OpenMPI library. if you need some more support, please refer to the siesta doc and/or ask on a siesta mailing list Cheers, Gilles On Monday, September 12, 2016, Mahmood Naderan <mahmood...@gmail.com> wrote: > Hi, > Trying to build a source code with newer versions of OpenMPI, I still have > some problems that weren't exist in previous versions. > > In 1.6.5, I wrote something in a arch.make file which is used by Makefile > > FC=/export/apps/siesta/openmpi-1.6.5/bin/mpif90 > MPI_INTERFACE=libmpi_f90.a > MPI_INCLUDE=. > > And then I had to copy that library to the local folder in order to drop > the full path. > > > > However, with 1.8.8, it has been stated that mpifort (the wrapper) > provides all necssary libraries.
