Makefile

# Makefile for iii (Comp 40 Assignment 2)
# 
# Includes build rules for sudoku, unblackedges, my_useuarray2, and my_usebit2.
#
# This Makefile is more verbose than necessary.  In each assignment
# we will simplify the Makefile using more powerful syntax and implicit rules.
#
# New syntax rules added:  wildcards (%.o, %.c) and special variables:
# $@ - the target of the rule
# $< - the first dependency
# $^ - all dependencies
#
# Last updated: February 4, 2016


############## Variables ###############

CC = gcc # The compiler being used

# Updating include path to use Comp 40 .h files and CII interfaces
IFLAGS = -I. -I/comp/40/include -I/usr/sup/cii40/include/cii

# Compile flags
# Set debugging information, allow the c99 standard,
# max out warnings, and use the updated include path
CFLAGS = -g -std=c99 -Wall -Wextra -Werror -Wfatal-errors -pedantic $(IFLAGS)

# Linking flags
# Set debugging information and update linking path
# to include course binaries and CII implementations
LDFLAGS = -g -L/comp/40/lib64 -L/usr/sup/cii40/lib64

# Libraries needed for linking
# Both programs need cii40 (Hanson binaries) and *may* need -lm (math)
# Only brightness requires the binary for pnmrdr.
LDLIBS = -lpnmrdr -lcii40 -lm

# Collect all .h files in your directory.
# This way, you can never forget to add
# a local .h file in your dependencies.
#
# This bugs Mark, who dislikes false dependencies, but
# he agrees with Noah that you'll probably spend hours 
# debugging if you forget to put .h files in your 
# dependency list.
INCLUDES = $(shell echo *.h)
