A simplish makefile for a "Hello, world" app. The code is all in the file main.cpp. It could be simpler yes... but this gives an idea of how things can be done without making it horribly complicated (see http://files.nxor.org/makefile).

code:

# #   "Hello, world" makefile #    # ######################################## # compiler & linker # CC = g++ LN = g++ ######################################## # build options # CXX_FLAGS = -g -Wall LN_FLAGS = LN_LIBS = ######################################## # rules #default rule all: hello # main main.o : main.cpp         ${CC} ${CXX_FLAGS} main.cpp -o main.o # the app        hello : main.o         ${LN} ${LN_FLAGS} ${LN_LIBS} main.o -o hello         # clean .PHONY : clean clean :         touch main.o         touch hello         rm main.o hello
