compiling macs in MacBook with Ventura

 I wanted to compile the coalescent simulator macs in the Mac running Ventura with M2 chips. This was of course the beginning of a great adventure. I end up doing the following:

- install library boost using homebrew

- dig out the path for the boost library e.g. as here, which turned out to be /opt/homebrew/Cellar/boost/1.81.0_1/include

- finally, modify the makefile as follows

# compile options

CFLAGS = -Wall -g

#CFLAGS = -Wall -O3

# Add location of any library locations below with -L

LINKFLAGS =

#LINKFLAGS = -static

# compiler

CC = g++

# libraries. For a local Boost installation

# Example:

#LIB = -I /Users/garychen/software/boost_1_36_0

# Default:

#LIB = -I .

LIB = -I /opt/homebrew/Cellar/boost/1.81.0_1/include

# simulator name

SIM=macs

OBJS = simulator.o algorithm.o datastructures.o

$(SIM) : $(OBJS)

$(CC) -o $(SIM) $(OBJS) $(LINKFLAGS)

simulator.o: simulator.cpp simulator.h

$(CC) $(CFLAGS) $(LIB) -c $<

algorithm.o: algorithm.cpp simulator.h

$(CC) $(CFLAGS) $(LIB) -c $<

datastructures.o: datastructures.cpp simulator.h

$(CC) $(CFLAGS) $(LIB) -c $<
