makefile opencv的案例

Posted 2022-05-21 ZONG_XP

 案例一

CXX = g++
LIBS +=`pkg-config --libs opencv`
INC +=`pkg-config --cflags opencv`
CPPFLAGS += -g -std=c++11 -Wall

SRCS = detect.cpp
TARGET = detect
OBJS = detect.o

$(TARGET):$(OBJS)
    $(CXX) $(INC) $(CPPFLAGS) $(OBJS) -o $(TARGET) $(LIBS)
$(OBJS):%.o:%.cpp
    $(CXX) $(INC) $(CPPFLAGS) -c $< -o $@

.PHONY:clean
clean:
    rm -r *.o $(TARGET)

案例二

CXX = g++
LDLIBS += `pkg-config --libs opencv`
INC += `pkg-config --cflags opencv`
CPPFLAGS += -g -std=c++11 -Wall -I./

TARGET = edges
OBJS = edges.o label.o
SRCS = edges.cpp label.cpp
HEAD = label.hpp

$(TARGET):$(OBJS)
    $(CXX) -o $(TARGET) $(OBJS) $(LDLIBS)

%.o:%.c $(HEAD)
    $(CXX) $(INC) $(CPPFLAGS) -c $> -o $@

.PHONY:clean
clean:
    rm -r *.o

案例三
