makefile简单写法

Published: at 01:45 PM | 1 min read
四个文件:error.h error.cpp def.h test.cpp
error.cpp包含error.h
test.cpp包含def.h error.h

makefile如下:
objects = test.o error.o
#flags = -D_DEBUG # debug版本

edit: $(objects)
g++ -o edit $(objects)

test.o: def.h test.cpp
g++ -c test.cpp
error.o: error.h error.cpp
g++ -c error.cpp

clean:
rm edit $(objects)

// ----------自动查找.h .cpp-------------------
CC = g++
CFLAGS = -Wall

COM = ../com
TEST = .

OBJ = $(COM)/ByteArray.o $(TEST)/ByteArrayTest.o

all:$(OBJ)
$(CC) $(CFLAGS) $(OBJ) -o test

clean:
rm *.o test

// 常用模板
TARGET  = ./chat
OBJPATH  = .
SOURCES  = $(wildcard *.cpp)
OBJS     = $(patsubst %.cpp,%.o,$(SOURCES))
FULLOBJS  = $(patsubst %.cpp,$(OBJPATH)/%.o,$(SOURCES))
INCPATH  = -I. -I./libevent/header
LIBPATH  = -L./libevent -levent_core -levent_threads
LFLAGS  = -w:
CFLAGS  = -w -c
CXX      = g++
all:$(TARGET)
$(TARGET):$(OBJS)
 $(CXX) $(LFLAGS) $(FULLOBJS) -o $(TARGET) $(LIBPATH)
$(OBJS):$(SOURCES)
 $(CXX) $(CFLAGS) $(DFLAGS) $*.cpp -o $(OBJPATH)/$@ $(INCPATH)
clean:
 rm -f $(OBJPATH)/*.o
 rm -f $(TARGET)
模板,如使用muduo库:
CXX=g++
CFLAGS=-Wall -I/home/tujiaw/muduo/include
LDFLAGS=-L/home/tujiaw/muduo/lib
LIBS=-lmuduo_base -lmuduo_net -lpthread
OBJS=main.o echo.o
out:$(OBJS)
 $(CXX) $(CFLAGS) $(OBJS) -o $@ $(LDFLAGS) $(LIBS)
%.o:%.cpp
 $(CXX) $(CFLAGS) -c $<
clean:
 rm out $(OBJS)
