# Instructions to get Absoft Pro Fortran for 
# Mac OSX, 32 and 64-bit Linux systems
# to work with MPICH version 1.2.4 

# These instructions assume that the Absoft compilers will 
# be used to compile both the FORTRAN 77 and Fortran90 parts
# of MPICH. If you have a symbolic link in /usr/bin between
# g77 and f77, then g77 will be used to compile the FORTRAN
# 77 code and the build will fail.

# Download  mpich.tar.gz using a web browser from: 
ftp://ftp.mcs.anl.gov/pub/mpi/mpich.tar.gz

# From the command line use:
ftp ftp.mcs.anl.gov
# Use anonymous as the user and your email address
# for the password.  Then cd to /pub/mpi: 
cd /pub/mpi
# make sure that binary transfer mode is set:
bin
# get the tar.gz file:
get mpich.tar.gz

# Unpack mpich.tar.gz like this:
tar -xzvf mpich.tar.gz

# Change your directory to mpich-1.2.4: 
cd mpich-1.2.4 

# Force all Fortran object file symbols to be in lower case
# and have trailing underscores (for compatibility with the 
# rest of the Absoft supplied libraries) and do the same for
# mpich by setting these environment variables:

export F90="f90 -YEXT_NAMES=LCS -YEXT_SFX=_"
export FC="f77 -f -N15"

# Configure and set the install directory for MPICH
# /me is your home directory
# /mpich is the name of the directory where MPICH will be 
# installed in to:

./configure --prefix=/home/me/mpich

# Build mpich by typing make:
make

# Install mpich by typing make install:
make install
