Hi,

this is the relevant part of your config.log


configure:1594: checking whether the Fortran compiler works
configure:1600: ./a.out
./a.out: symbol lookup error: /export/apps/siesta/openmpi-1.8.8/lib/libmpi_mpifh.so.2: undefined symbol: mpi_fortran_weights_empty
configure:1603: $? = 127
configure:1612: error: cannot run Fortran compiled programs.

it seems something is busted with this Open MPI install.

can you please run

nm /export/apps/siesta/openmpi-1.8.8/lib/libmpi_mpifh.so.2 | grep -i mpi_fortran_weights_empty nm /export/apps/siesta/openmpi-1.8.8/lib/libmpi.so.1 | grep -i mpi_fortran_weights_empty
ldd /export/apps/siesta/openmpi-1.8.8/lib/libmpi_mpifh.so.2

hopefully we will find out what is going wrong
(i'd like to make sure you are not using IntelMPI libmpi.so.1 with Open MPI libmpi_mpifh.so.2, that can happen if Intel MPI appears first in your LD_LIBRARY_PATH)

Cheers,

Gilles

Hi,
Following the suggestion by Gilles Gouaillardet (https://mail-archive.com/users@lists.open-mpi.org/msg29688.html), I ran a configure command for a program like this

​# ../Src/configure FC=/export/apps/siesta/openmpi-1.8.8/bin/mpifort --with-blas=libopenblas.a --with-lapack=liblapack.a --with-scalapack=libscalapack.a
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking for Fortran compiler default output file name... a.out
checking whether the Fortran compiler works... configure: error: cannot run Fortran compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.



The content of config.log is available at ​http://pastebin.com/LTxxRMwH

It seems that mpifort (the wrapper compiler) has different usage than previous mpif90

Any idea about that?


Regards,
Mahmood
