Cpp makedepend

Makedepend is a more automated way of writing makefiles. Rather than modifying the sourcefile, AND the makefile when modifying dependencies, makedepend reads your sourcefiles and generates the dependencies for you.

(all lines with file.o, followed by it's dependencies, and it's compile-instructions)

makedepend is run **BY** the command make. running make runs makedepend

makefile indentation **MUST USE TABS** not spaces

Examples

g++

## make
##
PROG   = helloworld			## executable name
OBJS   = helloworld.cpp		## prog's source (.cpp), header (.h), and all required objects (.o)
CC     = g++					## compiler to use
DEBUG  = -g						## flag to allow gdb
CFLAGS = -Wall $(DEBUG)		## compilation flags
LFLAGS = -Wall $(DEBUG)		## library flags

## makedepend
SRCS   = helloworld.cpp		## a list of srcs (.cpp/.h) to check for #includes in

BINDIR = bin
   dummy_build_folder := $(shell mkdir -p $(BINDIR))



## instructions to compile the program,
## and each object file.
$(PROG): $(OBJS)
	$(CC) $(CFLAGS) -o bin/$(PROG) $(OBJS)
 
.C.o:
	$(CC) $(CFLAGS) -c $*.C




## Instructions for 'make clean', building dependencies, etc.
clean:
	rm -f *.o $(PROG)
 
depend:
	makedepend -- $(CFLAGS) -c -- $(SRCS)
