compiling issues Date: 2017/04/08 20:11 Name: Luca Dear Developers I am experiencing issues when compiling openmx3.8. My OS is a CentOS release 6.3 my hardware is Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz my compiler is parallel_studio_xe_2017.2.050 with OPENMPI-2.0.2 my makefile has the following lines: CC = mpicc -O3 -Dscalapack -xHOST -ip -no-prec-div -qopenmp -I/home/luca/intel/mkl/include/fftw FC = mpif90 -O3 -xHOST -ip -no-prec-div -qopenmp LIB= -L/home/luca/intel/mkl/lib -mkl=parallel -lmkl_scalapack_lp64 -lmkl_blacs_openmpi_lp64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -lpthread -lifcore -lmpi When running make I get the error: elpa1.o: In function `elpa1_mp_tridiag_real_': elpa1.f90:(.text+0x2ef): undefined reference to `mpi_comm_rank_' elpa1.f90:(.text+0x30d): undefined reference to `mpi_comm_size_' elpa1.f90:(.text+0x328): undefined reference to `mpi_comm_rank_' elpa1.f90:(.text+0x346): undefined reference to `mpi_comm_size_' elpa1.f90:(.text+0x11e8): undefined reference to `mpi_allreduce_' elpa1.f90:(.text+0x1570): undefined reference to `mpi_bcast_' ......... Could you please help me ? P.S I erased -lmpif90 -lmpif77 from he makefile because I get the error: cannot find -lmpi_f90

Ozaki Hi, > P.S I erased -lmpif90 -lmpif77 from he makefile because > I get the error: cannot find -lmpi_f90 Please check a directory where the MPI Fortran libraries are stored, and point the directory by "-L". Also, please take a look at the page 11 of the following PDF file: http://www.openmx-square.org/tech_notes/OpenMX-Compile.pdf Regards, TO Re: compiling issues ( No.2 ) Date: 2017/04/09 21:45 Name: Luca Dear prof. Ozaki thank you for your answer and hints. I was able to compile adding the line -L/home/luca/.../openmpi-202/lib -lmpi_usempif08 All the best. Luca
