[ECOS] about makefile

[=?gb2312?B?1cUgwcE=?= <johnsonest at hotmail dot com>]

Dear nickg,
  i have difficulty in orgnizing my header file and source file with 
makefile:
I create two folder ,named after "include" and "src" in current directory:
> ls
include src test.c

in test.c, i want to call codes in "include" and "src" folder:

#include <stdio.h>
#include "cs.h" //in include folder

int main()  
{
....
...
call fucntions in  file "cs.c" in folder "src"
...


}

to compile this
my makefile is:

HEADER_DIR = include
test:  test.o cs.o 
	gcc -o test  test.o cs.o 
	
test.o: test.c cs.h 
	gcc -c test.c  
cs.o : cs.c cs.h
        gcc -c cs.c -I$(SOURCE_DIR)  
clean:
	-rm *.o

but:
> make
make: *** No rule to make target `cs.c', needed by `cs.o'.  Stop.
in fact,my cs.c is a set of functions called each other,no entry function.

i am a newcomer about makefile,could you check my makefile ,tell me where 
error occur?


thank you very much !!!!!!!!!!!!!
