Question

I have simple files:
hello.h , hello.cpp

I have created a makefile in order to generate a static library (libhello.a)
but I’m getting error message , what am I doing wrong?

My code is:

CC = g++
CFLAGS = -Wall -g
utilObjs = hello.o

libhello.a: $(utilObjs)
    ar rc $@ $(utilObjs)
    ranlib $@

hello: hello.o libhello.a
    $(CC) $(CFLAGS) hello.o -L ./ -lutil -o $@

hello.o: hello.cpp hello.h
    $(CC) $(CFLAGS) -c $>

clean:
    rm -rf *.o libhello.a hello

all: hello 
.PHONY: all clean

The error message :
g++: fatal error: no input files
compilation terminated

I don’t think $> means anything special, change it to $< , which expands to the first prerequisite of the rule. (hello.cpp in this case)
