Hi,
1)
I am getting a frustrating message having to
do with linking a simple fortran program
Typing
/opt/local/lib/openmpi/bin/mpif90 tmp.f
Yields with gfortran.
Undefined symbols for architecture x86_64:
"_mpi_get_address0dr4_", referenced from:
_MAIN__ in ccGWs06E.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
I have attached the program, which runs fine on a linux box
test_usempi.f
Description: Binary data
2) The --showme gives /opt/local/bin/gfortran-mp-4.8 -I/opt/local/include/openmpi -Wl,-commons,use_dylibs -I/opt/local/lib -L/opt/local/lib -lmpi_usempi -lmpi_mpifh -lmpi Using gfortran-4.7 makes no difference. 3) Examining the file /opt/local/lib/libmpi_usempi.dylib with nm libmpi_usempi.dylib | grep 'address0dr4_' gives 0000000000000bf0 T _mpi_address0dr4_ Something I'm missing …. but shouldn't that be mpi_get_address0dr4_ 4/ Changing the USE mpi command to include 'mpif.h' works just fine. Shouldn't they be identical.
test_mpifh.f
