## Define CC to be the C compiler you wish to use.  The GNU cc
## compiler (gcc) should work, at the very least
#CC=cc
#CC=gcc

## 
## Define PERL to point to your local Perl interpreter.  It
## should be Perl 5.x, although it's conceivable that Perl 4
## might work ... I haven't tested it.
##
#PERL=/usr/bin/perl
#PERL=perl

## Define platform-dependent variables for use of floating-point code.

## Add to definition of CFLAGS depending on use of floating-point code.
##

##
## Define LIBS to include any libraries you need to link against.
## If NO_TABLE is define, LIBS should include '-lm' or whatever is
## necessary to bring in the math library.  Otherwise, it can be
## left alone, unless your system has other peculiar requirements.
##
LIBS=-L../mpi -lmpi -lm#-lmalloc#-lefence

##
## Define INCLUDES to include any include directories you need to 
## compile with.  
##
INCLUDES=-I../mpi

## Define RANLIB to be the library header randomizer; you might not
## need this on some systems (just set it to 'echo' on these systems,
## such as IRIX)
##
RANLIB=echo

## 
## Define LIBOBJS to be the object files that will be created during
## the build process.
