# Make is an arcane and powerful tool.  While this Makefile will accomplish
#  the purpose for which it was written, there are many possible variations
#  and optimizations that one could use even for a project this small.
# See the documentation on make for more information.

# Tell make which C compiler to use.
CC = gcc

# The first rule is executed if you run make without any parameters.
#  This line says that to make all, we should make the 'queens' rule below.
all:		queens

# These lines establish dependencies.  We need make to know that the
#  object file queens.o depends on both queens.c and queens.h
queens.o:   	queens.c queens.h
# This line tells make how to build the object file.  It is not required.
	$(CC) -c queens.c

printboard.o:	printboard.c queens.h
	$(CC) -c printboard.c

checkboard.o: 	checkboard.c queens.h
	$(CC) -c checkboard.c

# This line says that the queens executable depends on the object files.
queens:		queens.o printboard.o checkboard.o
# This line tells make how to link the .o files into an executable.
#  (Note: the tab at the beginning of the next line is essential.)
	$(CC) queens.o printboard.o checkboard.o -o queens

# This line deletes the executable, all object files, and all core files.
#  Type "make clean" when you are preparing to turnin your code.
clean:
	rm -rf *.o queens core*
