Example Makefile for Static Library

January 11, 2005

This is just a simple template. There's always the option of looking at a more complete manual.

# source files.
SRC =  	file1.cpp file2.cpp file3.cpp
OBJ = $(SRC:.cpp=.o)
OUT = ../libutils.a
# include directories
INCLUDES = -I. -I../include/ -I/usr/local/include
# C++ compiler flags (-g -O2 -Wall)
# compiler
CCC = g++
# library paths
LIBS = -L../ -L/usr/local/lib -lm
# compile flags
default: dep $(OUT)
	$(CCC) $(INCLUDES) $(CCFLAGS) -c $< -o $@
$(OUT): $(OBJ)
	ar rcs $(OUT) $(OBJ)
depend: dep
	makedepend -- $(CFLAGS) -- $(INCLUDES) $(SRC)
	rm -f $(OBJ) $(OUT) Makefile.bak

nice example, i dont know what the problem with the other guys was. Also if all your directory .cpp files are sources you can do like that: SRC := $(wildcard *.cpp)

thanks so much for ur example! it's really simple (especially among others in the internet) and helped me to start with my own Makefile for static c++ library ^^

can anybody explain the below line: OBJ = $(SRC:.cpp=.o) please...
Comment September 26, 2015 by digitalpeer
This is called substitution references: http://www.gnu.org/software/make/manual/make.html#Substitution-Refs OBJ = $(SRC:.cpp=.o) This is creating a variable called OBJ that contains all of the items listed in SRC with a .cpp extension converted to a .o extension- and it also includes everything else as is without a .cpp extension. So, in the example it will end up being this: OBJ = file1.o file2.o file3.o Automatic conversions like this are useful because you can just modify one variable (SRC) and all of the other variables automatically populate as expected. In the simple example, OBJ is just used to clean the compiled object files- one per source file.
