### 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 := mushroom.exe
LIBS := alleg

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

CFLAGS := -g -Wall -O3 -m486
CXXFLAGS := $(CFLAGS)

# 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.
#

ifneq ($(wildcard $(DJDIR)/bin/rm.exe),)
RM-F := rm -f
else
RM-F := del
endif

# You shouldn't need to change anything below this point.
#
# 从这里开始，你应该不需要改动任何东西。（我是不太相信，太ＮＢ了！）
