Need help with lab homework:

# Makefile:
#        It uses the C++ Compiler with all warnings and
#        full debugging; will create a single executable called 'main'
# ---------------------------------------------------------------
# Note: If you want to use the g++ compiler on pegasus or helios
# uncomment the g++ lines and comment the Digital Unix lines

# the Digital Unix C++ compiler needs these lines:
CPP = cxx
CFLAGS = -L/usr/lib/cmplrs/cxx -DPOSIX_4D9 -w0 -gall

# the g++ compiler on pegasus and helios needs these lines:
# CPP = g++
# CFLAGS = -DPOSIX_4D9 -w -g

# link in the math library
LFLAGS = -lm

RM = rm -f
# ----------------------------------------------------------------
# Explanation of macros:
#     $< is any dependent file which is out of file1
#     $* is the target's basename (without extension)
#     $@ is the target's fullname
# add suffix .cpp since it is not a default with make util
.SUFFIXES:     .cpp .o
# implicit rule for compilation only:
     :{CPP} -c ${CFLAGS} $<

OFILES=          main.o

# dependencies
default:     main    
main:           $(OFILES)
     {CPP} ${CFLAGS} ${LFLAGS} $(OFILES) -o $@

main.o:          main.cpp

     ${RM} *.o

I am not terribly familliar with make files but this looks iffy:

     :{CPP} -c ${CFLAGS} $<

I'd suspect it should be

     {CPP} -c ${CFLAGS} $<
