### Customising
#
# Adjust the following if necessary; EXECUTABLE is the target
# executable's filename, and LIBS is a list of libraries to link in
# (e.g. alleg, stdcx, iostr, etc). You can override these on make's
# command line of course, if you prefer to do it that way.
#

EXECUTABLE := dt
LIBS := pcap dl iconv

# Now alter any implicit rules' variables if you like, e.g.:

CC := gcc
CFLAGS := -Wall -O2 -Iinclude/ -Werror
CXXFLAGS := $(CFLAGS)

# You shouldn't need to change anything below this point.

SOURCE := $(wildcard *.c */*.c */*/*.c */*/*/*.c)
OBJS := $(patsubst %.c,%.o,$(SOURCE))
DEPS := $(patsubst %.o,%.d,$(OBJS))
MISSING_DEPS := $(filter-out $(wildcard $(DEPS)),$(DEPS))
MISSING_DEPS_SOURCES := $(wildcard $(patsubst %.d,%.c,$(MISSING_DEPS)))
CPPFLAGS += -MD
