# --------------------------------- #
# This is the Makefile for EZRide.  #
# --------------------------------- #

# NX, NY defined?
# -------------------
# If you wish to specify NX, NY (the number of grid points in each direction)
# at compile time, then uncomment the following and set the values to what you
# want.  They need not all be set.  Those that are set will be ignored in
# task.dat.

# NOPTION = -DNX=61 -DNY=61 

# ---------------------
# Choose Graphics mode
# ---------------------

# If you want graphics, define this to 1, otherwise define it to 0:
GRAPHICS=1

#---------------------
# Choose Kinetics
#---------------------

KINETICS=Barkley
#KINETICS=FHN


# -------------------
# Choose the compiler
# -------------------

# EZRide follows the style of EZSpiral so hopefully
# conforms to the ANSI C standard and *should* compile with any C
# compiler.  
# Note however this was mostly tested on Macs
# Use at least the -O2 compiler option, the others are optional
# options.  If you use warning options such as -Wall (which you should use if
# you modify the code), then you may get some warnings. These are probably OK.


# Compiler flags appropriate for the GNU C compiler
# -------------------------------------------------

CC = gcc 
CFLAGS = -g -O0 -Wall -I/usr/X11R6/include -DFHN=$(KIN) -DGRAPHICS=$(GRAPH)

# ------------------------
# Set the linked libraries
# ------------------------

# OpenGL with X
# -------------

LD_LIBRARY_PATH=/usr/X11R6/lib
# The next line is for MacOSX; in normal unix it probably should be something simpler
LDFLAGS = -L/usr/X11R6/lib -lGL -lX11 -Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib
