How to create proper makefile

Question

I have problem with my makefile. Tree of my project looks as follow:

makefile/ makefile
source/ main.cpp
includes/ first.hpp,

and i have following makefile:

program.o: main.o

      g++ -o program main.o

main.o: /home/project/source/main.cpp, /home/project/include/first.hpp

      g++ -c /home/project/source/main.cpp /home/project/include/first.hpp

How i can create makefile without paths? I mean something like this:

program.o: main.o

       g++ -o program main.o

main.o: main.cpp, first.hpp

     g++ -c main.cpp first.hpp

And here's a generic makefile I wrote which handles dependency generation. It's for C, but can be converted to C++ trivially.

Make is pretty smart and has a number of built-in rules already. Get to know these rules and the predefined macros like CXX, CFLAGS, LDFLAGS, etc. Here's about the simplest Makefile that should build your program:

program: main.o
    $(CXX) $(LDFLAGS) -o $@ $<
main.o: main.cpp first.hpp
