RedHat 9 (Linux i386) - man page for hcc (redhat section 1)

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.	 Transla-
       tion  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 sup-
       port (if ROMIO/C++ support 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 sec-
       tion, 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 ./config-
       ure was invoked) as the local native C compiler, but this can be overridden by the  LAMHCC
       environment  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  vari-
       able CXX before invoking ./configure) by default, but this can be overridden by the LAMHCP
       environment variable.

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++ program.

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.
