I have a simple makefile as follow:

==================================

all: $(MAIN_TARGET)

$(MAIN_TARGET): hello.o

hello.o: hello.c

VPATH = include src bin

==================================

how do i configure this makefile so that the output files, .o and .exe
files goes into a bin sub directory? my .c files are in src directory

I tried writing explicit rules

%.o: %.c;  $(CC)  $(CFLAGS)   $(CPPFLAGS) -c -o $(OUTPUT_DIR)/$@ $<
%.o: %.cc; $(CXX) $(CXXFLAGS) $(CPPFLAGS) -c -o $(OUTPUT_DIR)/$@ $<
%: %.o;    $(CC)  $(LDFLAGS) $(OUTPUT_DIR)/$^ $(LOADLIBES) $(LDLIBS) -o bin/$@
%.exe: %.o;  $(CC)  $(LDFLAGS) $(OUTPUT_DIR)/$^ $(LOADLIBES) $(LDLIBS) -o bin/$@

and it sort of works, but it has problems sometimes (finding dependencies)...
