Makefile help

suppose i have mainprog.cpp that uses program.h.
how do i create a makefile and how do i run it?

Something like

Code:

mainprog.o : mainprog.cpp program.h
	$(CXX) -c mainprog.cpp

prog : mainprog.o
	$(CXX) -o prog mainprog.o

Note the indent before each $CXX is a real tab character, not spaces. This will catch you out.

You save this file as Makefile, and you run it by typing make at the command line prompt.
