Makefile

• Stores the recipe on how to build the program
• Analyzes dependencies and only recompiles what is really needed

Consists of rules like:

target: dependencies
    command
    command
    command

• Use one TAB for indenting not space

make -f <makefile>

• Example Makefile

CC = c++
CPPFLAGS = -std=c++14 -g -Wall -I../include
LDFLAGS = -L../lib
OBJS = build/*.o

build/main: build/main.o
    $(CC) build/main.o $(LDFLAGS) -o build/main

build/main.o: src/*.cpp
    @mkdir -p build
    $(CC) $(CPPFLAGS) -c src/main.cpp -o build/main.o

clean:
    rm -r build
