error in Makefile


Hi everyone
Iam doing something wrong with my Makefile. I have 2 executables server and client, 1 header network.h and network.c. When i write $make all it doesn't find network.c the but it works when i write $ gcc -o server server.c network.c -lpthread.
What are i doing wrong in TARGETS ?? HEADER can i deleted ??

Code:
CFLAGS = -Wall -g
CC = gcc
TARGETS = server client network.o
LDLIBS = -lpthread 
HEADER = network.h


all:	$(TARGETS) 
	$(CC) -o $@ $^ $(LDLIBS) $(CFLAGS)
	@echo Server && Client OK	


server:	server.c
	$(CC) -o $@ $^ $(LDLIBS) $(CFLAGS)


client:	client.c
	$(CC) -o $@ $^ $(LDLIBS) $(CFLAGS)


network.o:	network.c network.h
	gcc -c network.c


clean:
	@echo Cleaning 
	rm -f $(TARGETS) *.o *.~ *.out *.c~
	@echo OK.

.PHONY:	clean

Code:
all:	$(TARGETS) 
	$(CC) -o $@ $^ $(LDLIBS) $(CFLAGS)
	@echo Server && Client OK
$@ expands to the name of the target, so the second line causes gcc to make an executable called "all". I don't think you need this line at all.

&& is a shell operator, so the last line echo's "Server", then tries to execute a command called Client, you should write
Code:
@echo "Server && Client OK" 
   or
@echo Server and Client OK
