Makefile does not find rule for object - c

Question

I have a beginner's question about a Makefile. I have a very simple makefile containing:
SHELL = /bin/sh
CC = gcc
CFLAGS = -lm -std=c99 -g -o0
EXEC = test
BUILDDIR = build
OBJDIR = obj
SOURCES = $(shell cat sources.list)
DEPS = $(shell cat headers.list)
OBJ = $(SOURCES:.c=.o)
OBJECTS = $(patsubst %,$(OBJDIR)/%,$(OBJ))
all: $(OBJECTS)
$(CC) $(CFLAGS) $(OBJECTS) -o $(BUILDDIR)/$(EXEC)
$(OBJDIR)/%.o: %.c $(DEPS)
$(CC) -c $< -o $#
clean:
rm -f $(BUILDDIR)/$(EXEC) $(OBJDIR)/*.o
My Problem is, if I try to use this Makefile to compile, it returns the error message:
there is no rule for the target obj/Name.o
What am I doing wrong?
After the first few comments and further research I got to this working Version, but it does not create the object files in the obj folder, so it is not what I aim for
SHELL = /bin/sh
CC = gcc
CFLAGS = -lm -std=c99 -g -o0
EXEC = test
BUILDDIR = build
OBJDIR = obj
SOURCES = $(shell cat sources.list)
DEPS = $(shell cat headers.list)
OBJ = $(SOURCES:.c=.o)
OBJECTS = $(patsubst %,$(OBJDIR)/%,$(OBJ))
all: $(BUILDDIR)/$(EXEC)
$(BUILDDIR)/$(EXEC): $(OBJ)
$(CC) $(CFLAGS) $(OBJ) -o $(BUILDDIR)/$(EXEC)
%.o: %.c $(DEPS)
$(CC) -c $< -o $#
clean:
rm -f $(BUILDDIR)/$(EXEC) $(OBJDIR)/*.o

Answer 1

Are all the files in headers.list present at the right place ?
By the way, this is not a good way to handle dependencies on headers. You should take a look at -MP and -MDD and other options of your preprocessor to generate dependencies.

Answer 2

A classical makefile which should do what you need:
SHELL=/bin/bash
CC=gcc
CFLAGS=-std=c99 -g -o0
LDFLAGS=-lm
EXEC=test
BUILDDIR=build/
OBJDIR=obj/
SOURCES=$(shell cat sources.list)
OBJECTS=$(patsubst %.c,$(OBJDIR)%.o,$(notdir $(SOURCES)))
vpath %.c $(sort $(dir $(SOURCES)))
.PHONY:all mrproper clean depends
all:$(BUILDDIR)$(EXEC)
$(BUILDDIR)$(EXEC):$(OBJECTS)|$(BUILDDIR)
$(CC) $(CFLAGS) $^ -o $# $(LDFLAGS)
$(OBJDIR)%.o:%.c|$(OBJDIR)
$(CC) -c $< -o $#
$(BUILDDIR) $(OBJDIR):
mkdir $#
mrproper:clean
rm -f $(BUILDDIR)$(EXEC)
clean:
rm -f $(OBJECTS)
depends:
#rm -f dependencies.mk
#for i in $(SOURCES); do $(CC) -MM $$i -MT $(OBJDIR)`basename $$i | sed s:.c$$:.o:` >> dependencies.mk; done
include $(wildcard dependencies.mk)
If something is not clear, let me know.
Usage:
make depends
make
