Hello EasyBuilders! I have started building the foss-2016b toolchain on a new server and I am stumbling against an error that I have never seen before and for which I cannot pinpoint the cause.
When I try to compile a fortran source with mpifort (or mpif90), I get the error you see below. The thing I do not understand is why the linker searches for /usr/lib64/libgfortran.so (which does not exist for obvious reasons) instead of the equivalent library built by EasyBuild with GCCcore-5.4.0 (which exists). The LD_LIBRARY_PATH env var contains the path to the GCCcore directory where libgfortran.so is actually located. Why is ld ignoring this path? Any suggestion? Thanks! $ mpifort multitask_mpi.f90 /accre/arch/easybuild/software/Compiler/GCCcore/5.4.0/binutils/2.26/bin/ld.gold: error: cannot open /usr/lib64/libgfortran.so: No such file or directory /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_date_and_time' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_st_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_transfer_integer_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_string_trim' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_transfer_character_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_transfer_integer_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_transfer_integer_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_transfer_character_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_transfer_integer_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_transfer_character_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_transfer_character_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_string_trim' /tmp/ccpSxqE6.o:multitask_mpi.f90:function timestamp_: error: undefined reference to '_gfortran_st_write_done' /tmp/ccpSxqE6.o:multitask_mpi.f90:function p0_receive_output_: error: undefined reference to '_gfortran_st_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function p0_receive_output_: error: undefined reference to '_gfortran_st_write_done' /tmp/ccpSxqE6.o:multitask_mpi.f90:function p0_receive_output_: error: undefined reference to '_gfortran_st_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function p0_receive_output_: error: undefined reference to '_gfortran_st_write_done' /tmp/ccpSxqE6.o:multitask_mpi.f90:function p0_receive_output_: error: undefined reference to '_gfortran_st_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function p0_receive_output_: error: undefined reference to '_gfortran_st_write_done' /tmp/ccpSxqE6.o:multitask_mpi.f90:function MAIN__: error: undefined reference to '_gfortran_stop_string' /tmp/ccpSxqE6.o:multitask_mpi.f90:function MAIN__: error: undefined reference to '_gfortran_transfer_real_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function MAIN__: error: undefined reference to '_gfortran_stop_string' /tmp/ccpSxqE6.o:multitask_mpi.f90:function MAIN__: error: undefined reference to '_gfortran_transfer_real_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function MAIN__: error: undefined reference to '_gfortran_stop_string' /tmp/ccpSxqE6.o:multitask_mpi.f90:function MAIN__: error: undefined reference to '_gfortran_transfer_real_write' /tmp/ccpSxqE6.o:multitask_mpi.f90:function MAIN__: error: undefined reference to '_gfortran_stop_string' /tmp/ccpSxqE6.o:multitask_mpi.f90:function main: error: undefined reference to '_gfortran_set_args' /tmp/ccpSxqE6.o:multitask_mpi.f90:function main: error: undefined reference to '_gfortran_set_options' collect2: error: ld returned 1 exit status -- Davide Vanzo, PhD Application Developer Adjunct Assistant Professor of Chemical and Biomolecular Engineering Advanced Computing Center for Research and Education (ACCRE) Vanderbilt University - Hill Center 201 (615)-875-9137 www.accre.vanderbilt.edu
