hf77, mpif77 - Compile LAM FORTRAN programs.
SYNTAX
hf77 [-showme] ...
see f77(1) (or whatever your underlying FORTRAN compiler
is) for all other options.
DESCRIPTION
hf77 is a convenience wrapper for the local native FORTRAN
compiler. Translation of a LAM program requires the link
age of the LAM essential services libraries which may not
reside in one of the standard search directories of ld(1).
hf77 passes its arguments along to the local native FOR
TRAN compiler along with the -L and -l options required by
LAM/MPI programs. This includes all necessary options for
ROMIO and/or C++ bindings support (if ROMIO/C++ support
was included when LAM was compiled).
mpif77 is now the same as hf77. See the NOTES section,
below.
By default, hf77 uses the FORTRAN compiler that was
selected when LAM was configured (with the --with-fc flag
to ./configure) as the local native FORTRAN compiler, but
this can be overridden by the LAMHF77 environment vari
able.
OPTIONS
-showme
Does not invoke the underlying FORTRAN compiler.
Instead, it shows the command line that would be
executed to compile the FORTRAN program.
NOTES
Previous versions of hf77 did not automatically link in
the MPI library. Starting with LAM version 6.3, since
hf77 has become the de facto LAM FORTRAN compiler, the
-lmpi option is now automatically passed to the underlying
compiler when linking LAM/MPI programs.
Previous versions of LAM included the mpif77 wrapper
script to automatically pass -lmpi to hf77. This script
is now obsolete since hf77 now includes -lmpi automati
cally. mpif77 is now a symbolic link to hf77 to ensure
backward compatibility.
