# This is a Makefile. Make sure it has that name.

# The first rule in a Makefile is the default. So, by default,
# this Makefile builds both prime and count_xs. You can write
# `make prime` or `make count_xs` on the command line to make
# just one
all: ttest

# This line says that `ttest` depends on `ttest.o` and `basestats.o`,
# and then how to build the target (ttest) from the dependencies
ttest: ttest.o basestats.o
	gcc -lm -o ttest ttest.o basestats.o

# Other rules are similar.
# Note that the name of this rule is used in a dependency above and that it is also the name of a file.
# Match is important
ttest.o: ttest.c ttest.h basestats.h
	gcc -lm -c ttest.c

basestats.o: basestats.c basestats.h
	gcc -lm -c basestats.c

# Very common in Makefiles, gets rid of intermediate files (and emacs temp files)
clean:
	rm *.o *~
