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

CC:=g++
CFLAGS := -g -Wall -O3
CPPFLAGS := $(CFLAGS)
CPPFLAGS += $(addprefix -I,$(INCLUDES))
CPPFLAGS += -MMD
#
# # The next bit checks to see whether rm is in your djgpp bin
# # directory; if not it uses del instead, but this can cause (harmless)
# # `File not found' error messages. If you are not using DOS at all,
# # set the variable to something which will unquestioningly remove
# # files.
#

RM-F := rm -f


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