Greg,
I tried using those flags, but I got the same error. If this helps,
here's my output from mpif77 -showme:
/usr/local/bin/gfortran -I/usr/local/lammpi/include -Wl,-u -
Wl,_lam_darwin_malloc_linker_hack -Wl,-multiply_defined,suppress -Wl,-
force_flat_namespace -Wl,-flat_namespace -Wl,-multiply_defined -
Wl,suppress -L/usr/local/lammpi/lib -llammpio -llamf77mpi -lmpi -llam
-ldl
Any ideas?
Thank you!
