一个小例子学习makefile

前言

makefile推荐资料为陈皓的跟我一起写makefile，需要pdf资源的可以私我

正文

目录结构

---include

------student.h

---src

------student.cc

------main.cc

---makefile

makefile文件

vpath %.h ./include

vpath %.cc ./src

CC = g++

object = main.o student.o

all: exe

exe: ${object}

    ${CC} -o $@ ${object}

#main.o: main.cc student.h

#    g++ -c $< -I./include

#student.o: student.cc student.h

#    g++ -c $< -I./include

${object}: %.o: %.cc student.h

    ${CC} -c $< -I./include

.PHONE:clean

clean:

    rm -rf ${object} exe 

student.h代码

#ifndef _STUDENT

#define _STUDENT

#include <string>

class Student

{

public:

    Student(int id,std::string name);

    std::string getName();

private:

    int id;

    std::string name;

};

#endif

student.cc代码

#include "student.h"

Student::Student(int id,std::string name):id(id),name(name){

}

std::string Student::getName()

{

    return name;

}

main.cc代码

#include<iostream>

#include"student.h"

using namespace std;

int main()

{

    int id = ;

    std::string name = "pcxie";

    Student pcxie(id,name);

    cout<<"hello world"<<endl;

    cout<<pcxie.getName()<<endl;

    return ;

}

执行make all后的目录结构

---include

------student.h

---src

------student.cc

------main.cc

---makefile

---main.o

---student.o

---exe
