This is a really simple makefile, for small projects
It will just build all of the *.c files in this directory into their own object files, and then output a linked binary to BINOUT
There is no tidy housekeeping / folder creating in this makefile
# the output binary name BINOUT?=main # a cross compile prefix (if you want one) CROSS_COMPILE?= # standard cflags CFLAGS:=-Wall -pedantic # standard lflags LFLAGS:= # a list of libraries you wish to link against LIBS:= #-------------------------------# SRCS:=$(wildcard *.c) DEPS:=$(addprefix .dep/,$(SRCS:.c=.d)) OBJS:=$(addprefix .obj/,$(SRCS:.c=.o)) LFLAGS+=$(addprefix -l,$(CLIBS)) GCC:=$(CROSS_COMPILE)gcc MAKE+=--no-print-directory .PHONY: all run clean new .%.dir all: $(BINOUT) run: all ./$(BINOUT) clean: rm -f $(DEPS) $(OBJS) $(BINOUT) new: clean @$(MAKE) all .%.dir: @if [ ! -d $* ]; then echo "mkdir -p $*"; mkdir -p $*; else echo "!mkdir $*"; fi @touch $@ $(BINOUT): $(OBJS) $(GCC) $(LFLAGS) $(filter %.o,$^) -o $@ $(OBJS): .obj/%.o: %.c ..obj.dir .dep/%.d $(GCC) $(CFLAGS) $*.c -c -o $@ $(DEPS): .dep/%.d: %.c ..dep.dir makefile $(GCC) $(CFLAGS) -MM -MT .obj/$*.o $*.c -o $@ include $(wildcard *.d)
