I had a doubt regarding Makefile..i have created a Makefile.But i get error like make: *** No rule to make target `main.c', needed by `main.o'. Stop.

My source files main.c,hello.c ,hello1.c resides in src directory and include files function.h function1.h resides in inc directory.These two directories src and inc are in work directory.Make file resides in work directory
---------------------------------------------------
CC=gcc
vpath src
vpath inc

CPPFLAGS=-I inc

main : main.o hello.o hello1.o
$(CC) -o $(CPPFLAGS) $<
..c.o:
main.o : main.c function.h function1.h
$(CC) -c $(CPPFLAGS) $<
hello.o : hello.c function.h
$(CC) -c $(CPPFLAGS) $<
hello1.o : hello1.c function1.h
$(CC) -c $(CPPFLAGS) $<

.PHONY clean:
rm -rf *.o
---------------------------------------------------
can nyone fix this problem plz???

I recently installed AMD APP SDK on linux(ubuntu), so when I tried to compile a sample by the command (make ) as shown in int doc, I got this information:
