# Makefile for Project 3


	### Variables ###
CXX = /uns/bin/g++      # The standard g++ compiler is broken.  Do NOT use it
CXXFLAGS = -Wall -ansi -g -fno-implicit-templates # Compiler flags
TARGET_NAMES = pq-test  # You can add more executables here

	### Rules ###

# The first target in a Makefile is the default.  That is, a simple "make"
# at the command line will build the "all" target for this Makefile.  
# Remember the general syntax for rules in a Makefile is:
# <target> : <dependancies>
#	<command1 to generate target>
#	<command2 to generate target>
#	  ...
#	<commandn to generate target>


## This makes everything
all : $(TARGET_NAMES)


## These rules make the pq-test program

# This executable depends on object code generated from PriorityQueue-test.cc
#  and the templated code generated by the instantiation file.  This line
#  builds (it does not compile) the pq-test executable
# The $@ variable is the name of the target; the $^ variable is 
#  list of all the dependancies
pq-test : PriorityQueue-test.o BinaryHeapInst.o
	$(CXX) $(CXXFLAGS) -Wl,-rpath,/uns/lib -o $@ $^

# This line compiles the object code.  It does not build the executable (see
#  above for the build line) The $< variable is the name of the 
# *first* dependancy
PriorityQueue-test.o : PriorityQueue-test.cc IPriorityQueue.hh BinaryHeap.hh
	$(CXX) $(CXXFLAGS) -c $<

# This line compiles the object code.  It does not build the executable (see
#  above for the build line) The $< variable is the name of the 
# *first* dependancy
BinaryHeapInst.o : BinaryHeapInst.cc IPriorityQueue.hh BinaryHeap.hh BinaryHeap.cc
	$(CXX) $(CXXFLAGS) -c $<


## You can add rules for creating more executables below


# This rule is a fake target -- that is, it doesn't generate any object
# files; rather, the "make clean" command will execute the following rm
# command (which cleans out your old object files and executable).
clean :
	rm -f *.o *~ $(TARGET_NAMES)


# And .... as a reward for reading through this entire Makefile, here is
# is some information on pattern rules!  =)
# 
# Quoth Evgeny Roubinchtein (evgenyr@cs.washington.edu):
#
# > You could also use "patten rules" to tell 'make' how to produce a
# > .o given a .cc.  You wouldn't then have to write rules like:
# >
# > FOO.o : FOO.cc
# >        $(CXX) $(CXXFLAGS) -o $@ $^
# >
# > for each .o you want to produce.
# >
# > Often, people also use automatic dependency generation with pattern
# > rules.  The sample Makefile Justin Husted has written (in /uns/examples)
# > uses pattern rules and automatic dependency generation.
