[OMPI users] symbol lookup error for a "hello world" fortran script

[Julien de Troullioud de Lanversin]

Hi all,


I am completely new to MPI (and relatively new to linux). I am sorry if the
problem I encountered is obvious to solve.

When I run the following simple test with mpirun:










*program hello_world use mpi integer ierr call MPI_INIT (
ierr ) print *, "Hello world" call MPI_FINALIZE ( ierr )end
program hello_world*


I get the following error :
*./test: symbol lookup error: /usr/lib/libmpi_mpifh.so.12: undefined
symbol: mpi_fortran_weights_empty*

I compiled the source code like this: mpifort -o test test.f90

I look up on the internet and I understand that it is a problem with the
shared library of open mpi. But I think I correctly added the open mpi lib
to ld_library_path (I added the first directory -- /usr/lib/openmpi/lib -- via
.bashrc). Here is an echo $LD_LIBRARY_PATH:

*$/usr/lib/openmpi/lib:/opt/intel/compilers_and_libraries_2016.1.150/linux/compiler/lib/intel64:/opt/intel/compilers_and_libraries_2016.1.150/linux/mpi/intel64/lib:/opt/intel/compilers_and_libraries_2016.1.150/linux/mpi/mic/lib:/opt/intel/compilers_and_libraries_2016.1.150/linux/ipp/lib/intel64:/opt/intel/compilers_and_libraries_2016.1.150/linux/compiler/lib/intel64:/opt/intel/compilers_and_libraries_2016.1.150/linux/mkl/lib/intel64:/opt/intel/compilers_and_libraries_2016.1.150/linux/tbb/lib/intel64/gcc4.4:/opt/intel/debugger_2016/libipt/intel64/lib:/opt/intel/compilers_and_libraries_2016.1.150/linux/daal/lib/intel64_lin:/opt/intel/compilers_and_libraries_2016.1.150/linux/daal/../compiler/lib/intel64_lin:/opt/intel/compilers_and_libraries_2016.1.150/linux/compiler/lib/intel64:/opt/intel/compilers_and_libraries_2016.1.150/linux/mpi/intel64/lib:/opt/intel/compilers_and_libraries_2016.1.150/linux/mpi/mic/lib:/opt/intel/compilers_and_libraries_2016.1.150/linux/ipp/lib/intel64:/opt/intel/compilers_and_libraries_2016.1.150/linux/compiler/lib/intel64:/opt/intel/compilers_and_libraries_2016.1.150/linux/mkl/lib/intel64:/opt/intel/compilers_and_libraries_2016.1.150/linux/tbb/lib/intel64/gcc4.4:/opt/intel/debugger_2016/libipt/intel64/lib:/opt/intel/compilers_and_libraries_2016.1.150/linux/daal/lib/intel64_lin:/opt/intel/compilers_and_libraries_2016.1.150/linux/daal/../tbb/lib/intel64_lin/gcc4.4:/opt/intel/compilers_and_libraries_2016.1.150/linux/daal/../compiler/lib/intel64_lin*

The path that my system uses at run time (/usr/lib/) is not in the library
path. I thus don't know why this path is used.

I would be thankful if anyone could help me with this issue.

Julien,

first, make sure you are using the Open MPI wrapper
which mpifort
should be /usr/lib/openmpi/bin if i understand correctly
then make sure you exported your LD_LIBRARY_PATH *after* you prepended
the path to Open MPI lib
in your .bashrc you can either
LD_LIBRARY_PATH=/usr/lib/openmpi/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
or directly
export LD_LIBRARY_PATH=/usr/lib/openmpi/lib:$LD_LIBRARY_PATH

then you can
ldd ./test
and comfirm all MPI libs (both C and Fortran) are pointing to Open MPI

Cheers,

Gilles

Gilles,


Thank you for your fast reply.

When I type whereis mpifort I have the following:
*mpifort: /usr/bin/mpifort.openmpi /usr/bin/mpifort

I made sure I exported the LD_LIBRARY_PATH after I prepended
/usr/lib/openmpi/lib.
The same error is produced.

If I type ldd ./test I get the following:

Julien,

the fortran lib is in /usr/lib/libmpi_mpifh.so.12
the C lib is the one from Intel MPI

i guess the C lib is in /usr/lib, and not /usr/lib/openmpi/lib
prepending /usr/lib is never recommended, so i suggest you simply remove

Gilles,


I went for the radical solution and completely removed intel prallel studio
from my system (I used it for ifort but I prefer to use gfortran now).

The script works now.

Thanks a lot for your help Gilles.

Julien,
first, make sure you are using the Open MPI wrapper
which mpifort
should be /usr/lib/openmpi/bin if i understand correctly
then make sure you exported your LD_LIBRARY_PATH *after* you prepended
the path to Open MPI lib
in your .bashrc you can either
LD_LIBRARY_PATH=/usr/lib/openmpi/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
or directly
export LD_LIBRARY_PATH=/usr/lib/openmpi/lib:$LD_LIBRARY_PATH
then you can
ldd ./test
and comfirm all MPI libs (both C and Fortran) are pointing to Open MPI
Cheers,
Gilles

to ld_library_path (I added the first directory --

The path that my system uses at run time (/usr/lib/) is not in the library
path. I thus don't know why this path is used.
I would be thankful if anyone could help me with this issue.
Best,
