一、多文件项目源代码

// include/add.hpp#pragma once
int add(int a, int b);

// include/sub.hpp#pragma once
int sub(int a, int b);

// src/add.cpp#include "add.hpp"int add(int a, int b) {return a + b;
}

// src/sub.cpp#include "sub.hpp"int sub(int a, int b) {return a - b;
}

// src/main.cpp#include <iostream>
#include "add.hpp"
#include "sub.hpp"int main() {std::cout << "10 + 5 = " << add(10, 5) << std::endl;std::cout << "10 - 5 = " << sub(10, 5) << std::endl;return 0;
}

二、静态库编译链接

l_options := $(library_names:%=-l%)
L_options := $(library_paths:%=-L%)compile_flags := $(I_options) -w -O3 -std=c++11
