Makefile模板

TARGET = ${notdir $(CURDIR)}

SRC_DIR = .
SRC_SUBDIR += . 
INCLUDE_DIR += .
OBJ_DIR = .

CC = gcc
C_FLAGS = -g -Wall
LD = $(CC)
INCLUDES += -I$(INCLUDE_DIR)
LD_FLAFS += 
LD_LIBS =

ifeq ($(CC), g++)
	TYPE = cpp
else
	TYPE = c
endif

SRCS += ${foreach subdir, $(SRC_SUBDIR), ${wildcard $(SRC_DIR)/$(subdir)/*.$(TYPE)}}
OBJS += ${foreach src, $(notdir $(SRCS)), ${patsubst %.$(TYPE), $(OBJ_DIR)/%.o, $(src)}}

vpath %.$(TYPE) $(sort $(dir $(SRCS)))

all : $(TARGET)
	@echo "Builded target:" $^
	@echo "Done"

$(TARGET) : $(OBJS)
	@mkdir -p $(@D)
	@echo "Linking" $@ "from" $^ "..."
	$(LD) -o $@ $^ $(LD_FLAGS) $(LD_LIBS)
	@echo "Link finished\n"

$(OBJS) : $(OBJ_DIR)/%.o:%.$(TYPE)
	@mkdir -p $(@D)
	@echo "Compiling" $@ "from" $< "..."
	$(CC) -c -o $@ $< $(C_FLAGS) $(INCLUDES)
	@echo "Compile finished\n"

.PHONY : clean cleanobj
clean : cleanobj
	@echo "Remove all executable files"
	rm -f $(TARGET)
cleanobj :
	@echo "Remove object files"
	rm -rf $(OBJ_DIR)/*.o

用法

编译C程序

make

编译C++程序

make CC=g++

或者将Makefile中的CC = gcc改成CC = g++，然后

make

其他

TARGET指定生成的可执行文件名，我这里用的是当前所在目录名
SRC_DIR指定源文件(.c .cpp)文件的路径, 如SRC_DIR = ./src
SRC_SUBDIR列举SRC_DIR下的子目录, 如SRC_DIR下有子目录"utils", SRC_SUBDIR += . utils
INCLUDE_DIR指定头文件路径, 如INCLUDE_DIR += ./include
OBJ_DIR指定中间文件存放路径, 如OBJ_DIR = ./obj
C_FLAGS指定编译参数选项
LD_FLAFS指定链接参数选项
LD_LIBS指定链接库, 如LD_LIBS += -lm

清除生成的文件：

# 清空全部生成文件
make clean
# 清空生成的中间文件
make cleanobj

Tips

对于Ubuntu系统，可以将Makefile文件复制到~/Templates（中文环境为~/模板）目录下，这样就可以在任意目录下右键添加该Makefile模板。

终端输入：

gedit ~/.bashrc

在~/.bashrc文件中添加一行

alias Makefile="cp ~/Templates/Makefile ./"

保存后输入：

source ~/.bashrc

生效之后，就可以通过在命令行输入Makefile，来创建Makefile模板了。

OpenCV Makefile模板

TARGET = ${notdir $(CURDIR)}

SRC_DIR = .
SRC_SUBDIR += . 
INCLUDE_DIR += .
OBJ_DIR = .

CC = g++
C_FLAGS = -g -Wall
LD = $(CC)

INCLUDES += -I$(INCLUDE_DIR) \
            -I/usr/local/include/opencv4/ \
            -I/usr/local/include


LD_FLAGS += -L/usr/local/lib/

LD_LIBS += -lopencv_core \
           -lopencv_highgui \
           -lopencv_imgcodecs \
           -lopencv_imgproc



ifeq ($(CC), g++)
	TYPE = cpp
else
	TYPE = c
endif

SRCS += ${foreach subdir, $(SRC_SUBDIR), ${wildcard $(SRC_DIR)/$(subdir)/*.$(TYPE)}}
OBJS += ${foreach src, $(notdir $(SRCS)), ${patsubst %.$(TYPE), $(OBJ_DIR)/%.o, $(src)}}

vpath %.$(TYPE) $(sort $(dir $(SRCS)))

all : $(TARGET)
	@echo "Builded target:" $^
	@echo "Done"

$(TARGET) : $(OBJS)
	@mkdir -p $(@D)
	@echo "Linking" $@ "from" $^ "..."
	$(LD) -o $@ $^ $(LD_FLAGS) $(LD_LIBS)
	@echo "Link finished\n"

$(OBJS) : $(OBJ_DIR)/%.o:%.$(TYPE)
	@mkdir -p $(@D)
	@echo "Compiling" $@ "from" $< "..."
	$(CC) -c -o $@ $< $(C_FLAGS) $(INCLUDES)
	@echo "Compile finished\n"

.PHONY : clean cleanobj
clean : cleanobj
	@echo "Remove all executable files"
	rm -f $(TARGET)
cleanobj :
	@echo "Remove object files"
	rm -rf $(OBJ_DIR)/*.o
