Can't add a path to makefile in Windows

Hi all,
I'm learning how to use makefile to build an executable file in Windows 7. The compiler I used is mingw32. I followed the examples 18-1 to 18-3 from the book <Practical C Programming>. Three files were used here: ia.c ia.h, and hist.h. This book provides some makefile examples and they work fine as long as I put all three files and makefile under one folder.
However, I wanted to see if I could make it when putting source files and header files into seperate folders. So I followed the traditional layout mentioned in the GNU make manual:

Code:

---

~/hist
|>---- Makefile
|>---- include
| |>---- ia.h
|>---- src
| |>---- hist.c
| |>---- ia.c

---

Now, I should use VPATH/vpath or -I../path. So I tried different combinations, but all of them failed. I really don't know why. Here's my makefile:

Code:

---

VPATH = C:\hist\include
Srcdir = -I C:\hist\src
CC = gcc
CFLAGS = -g -Wall
all: hist
hist: hist.o ia.o
  $(CC) $(CFLAGS) -o hist hist.o ia.o
 
hist.o: hist.c ia.h
  $(CC) $(Srcdir) $(CFLAGS) -c hist.c
 
ia.o: ia.c ia.h
  $(CC) $(Srcdir) $(CFLAGS) -c ia.c
clean:
  rm -f hist hist.o ia.o
-----------------------------------
The mingw gives me this error:
-----------------------
$ make
make: *** No rule to make target `hist.c', needed by `hsit.o'. Stop.
----------------------------------
I also tried the following possibility:
-----------------------------------
IDIR = -I C:\hist\include
SDIR = -I C:\hist\src
CC = gcc
CFLAGS = -g -Wall
all: hist
hist: hist.o ia.o
  $(CC) $(CFLAGS) -o hist hist.o ia.o
 
hist.o: hist.c ia.h
  $(CC) $(CFLAGS) -c c:\hist\src\hist.c ia.h
 
ia.o: ia.c ia.h
  $(CC) $(CFLAGS) -c ia.c ia.h
clean:
  rm -f hist hist.o ia.o

---

I got the same error. Then I tested the vpath method:

Code:

---

vpath %.c src
vpath %.h include
CC = gcc
CFLAGS = -g
srcf := hist.c ia.c
obj := hist.o ia.o
%: %.c
 $(obj) $^ -o $@
 
%.o: %.c
 $(srcf) $(obj) $<
clean:
  rm -f ia

---

Now I got no error, and the Mingw gives me this output:

Code:

---

$ make
rm -f ia
# gcc -g -o hist hist.o ia.o
# gcc -g -c c:\hist\src\hist.c ia.h
# gcc -g -c ia.c ia.h
# rm -f hist hist.o ia.o
# gcc -g -o hist hist.o ia.o
# gcc -g -c hist.c
# gcc -g -c ia.c
# rm -f hist hist.o ia.o

---

Regarding the vpath method, I tried the following ways too:

Code:

---

vpath %.c c:\hist\src
vpath %.h c:\hist\include
----------------------------
vpath %.c c:\\hist\\src
vpath %.h c:\\hist\\include
-------------------------------
vpath %.c c:/hist/src
vpath %.h c:/hist/include

---

Mingw gave me same output as above.
So what should I do to add the path? Any form of help would be appreciated! Thanks for reading.

Where is "hist.c"?

Oh, sorry for the typo... It's under folder src. There's no hist.h. I'm editting the original post.

The VPATH works. I just didn't do it right. Here is the code of the makefile:

Code:

---

VPATH = C:\hist\include c:\hist\src
CC = gcc
CFLAGS = -g -Wall -I c:\hist\include
all: hist
hist: hist.o ia.o
  $(CC) $(CFLAGS) -o hist hist.o ia.o
 
hist.o: hist.c ia.h
  $(CC) $(CFLAGS) -c $^
 
ia.o: ia.c ia.h
  $(CC) $(CFLAGS) -c $<
clean:
  rm -f hist hist.o ia.o

Thanks to every one who showed interest to this thread!
