Install via clib:
$ clib install WestleyR/arglib
Add this to your main code:
#include "arglib/arglib.h"Then add this to your CFLAGS:
CFLAGS = -I depsThen, here is a basic Makefile, combine this to your main project Makefile:
CC = gcc
DEPDIR = deps
SRCDIR = src
CFLAGS = -I $(DEPDIR) -std=c99 -Wall
LDFLAGS =
TARGET = test
SRC = $(wildcard $(SRCDIR)/*.c)
DEPS = $(wildcard $(DEPDIR)/*/*.c)
ALLFILE = $(notdir $(SRC) $(DEPS))
OBJS = $(ALLFILE:.c=.o)
