Error with Makefile

[sam wun]

Hi,

I don't know how to build a proper Makefile for a C++ project.
Here is the Makefile I m currently use:
CC = g++
CXXFLAGS = -O -pipe
INCS = -I/usr/local/include
#LIBS = -l/usr/local/lib/libregexx.a
#LIBS = /usr/local/lib/libregexx.la
#LIBS = -L/usr/local/lib -lregexx
LIBS = /usr/local/lib/libregexx.a

#LIBTOOL = $(SHELL) /usr/local/bin/libtool13
#CXXLINK = $(LIBTOOL) --mode=link $(CXXLD) $(AM_CXXFLAGS) $(CXXFLAGS) 
$(LDFLAGS) -o $@

OBJS = simple.o

PROGS = simple

all:    ${PROGS}

#simple: ${OBJS} simple.h
simple: ${OBJS}  ${LIBS}
       ${CC} ${CXXFLAGS} -o $@ ${OBJS} ${LIBS} ${INCS}
simple.o: simple.cpp
       $(CC) $(INCS) -c $< -o $@

clean:
       rm -f ${PROGS} *.o *.core

The Makefil generated the following error:
# make

Can anyone tell me how to correct this error?

Thanks
