# This file is used with the UNIX `make' command to compile ecgpuwave.  Install
# the WFDB library (see http://www.physionet.org/physiotools/wfdb.shtml), and
# copy wfdbf.c from the 'fortran' subdirectory of the WFDB sources into this
# directory, before attempting to compile ecgpuwave.
#
# 11 January 2016 (BEM):
# Updated wfdbf.c for compatibility with modern systems (including
# x86-64), and added the -fno-automatic option to avoid undefined
# behavior when compiling with gfortran.
#
# 21 July 2013 (GBM):
# Incorporated modifications to dades.f, ecgpuwave.f, and this Makefile for
# compatibility with gfortran (thanks to Roberto Sassi!)
#
# 24 March 2010 (GBM):
# The -m32 option for F77 and CC forces compilation of 32-bit executables,
# even on a 64-bit platform, because 64-bit executables of ecgpuwave fail
# due to a mismatch in the default sizes of integer variables in Fortran and
# int variables in C.  This can probably be remedied by declaring all
# of ecgpuwave's integer variables as INTEGER*8 when compiling a 64-bit
# executable, but that would cause worse problems on 32-bit platforms.
# This has been tested using g77 and gcc on 32- and 64-bit Linux (Fedora 12).
# If your 32-bit compilers don't support the -m32 option, remove it.

CC=gcc
CFLAGS=-g -O
F77=gfortran -std=legacy -ffixed-line-length-none -fno-automatic

# On an x86-64 system, if you need to reproduce the exact results
# produced on an IA-32 system, you can uncomment the following line:
#FFLAGS=-g -O -Wextra -mfpmath=387
