HF77(1) LAM TOOLS HF77(1)NAME
mpif77, hf77 - Compile LAM FORTRAN programs.
SYNOPSIS
hf77 [-showme] ...
DESCRIPTION
See f77(1) (or whatever your underlying FORTRAN compiler is) for all other options.
The name hf77 has been deprecated in favor of mpif77. Please see its corresponding man page.

HCC(1) LAM TOOLS HCC(1)NAME
hcc, mpicc, hcp, mpiCC - Compile LAM C/C++ programs.
SYNTAX
hcc [-showme] ...
hcp [-showme] ...
see cc(1) and CC(1) (or whatever your underlying C/C++ compilers are) for all other options.
DESCRIPTION
hcc and hcp are convenience wrappers for the local native C and C++ compilers. Translation of a LAM program requires the linkage of the
LAM specific libraries which may not reside in one of the standard search directories of ld(1). It also often requires the inclusion of
header files what may also not be found in a standard location. hcc passes its arguments to the local native C compiler along with the -I,
-L and -l options required by LAM programs. This includes all necessary options for ROMIO and/or C++ bindings support (if ROMIO/C++ sup-
port was included when LAM was compiled). hcp is similar, but invokes the native C++ compiler instead.
mpicc is now the same as hcc, just as mpiCC is now the same as hcp. See the NOTES section, below.
By default, hcc uses the C compiler that was selected when LAM was configured (with the --with-cc flag to ./configure, or by setting the
environment variable CC before ./configure was invoked) as the local native C compiler, but this can be overridden by the LAMHCC environ-
ment variable. Likewise, hcp uses the C++ compiler that was selected when LAM was configured (with the --with-cpp flag to ./configure, or
by setting the environment variable CXX before invoking ./configure) by default, but this can be overridden by the LAMHCP environment vari-
able.
OPTIONS -showme
Does not invoke the underlying C/C++ compiler. Instead, it shows the command line that would be executed to compile the C/C++ pro-
gram.
NOTES
Previous versions of hcc and hcp did not automatically link in the MPI library. Starting with LAM version 6.3, since hcc and hcp have
become the de facto LAM C and C++ compilers, the -lmpi option is now automatically passed to the underlying compiler when linking LAM/MPI
programs.
Previous versions of LAM included the mpicc and mpiCC wrapper scripts to automatically pass -lmpi to hcc and/or hcp. These scripts are now
obsolete since hcc and hcp now include -lmpi automatically. mpicc and mpiCC are now symbolic links to hcc and hcp, respectively, to ensure
backward compatibility.
