Hello,
Set LAMHF77=ifort in your environment for proper compiling. If using
bash,
export LAMHF77=ifort
There is no need to link MPI or Intel libraries explicitly. Use mpif77 to
compile and link. Make certain to use the same processor options when
linking as were used when compiling, or ifort may give undefined symbols.
