概述

linux下多线程需要使用pthread库，通过 #include<thread>包含所需的函数及方法；C11才开始引入线程的概念

CMake

需要连接到pthread库，target_link_libraries(threads pthread)

cmake_minimum_required(VERSION 3.5.1)
project(threads)
add_executable(threads threads.cpp)set(CMAKE_SYSTEM_NAME Linux)SET(CMAKE_CXX_FLAGS "--std=c++11")
target_link_libraries(threads pthread)

测试代码

#include <chrono>
#include <iostream>
#include <thread>void worker(int index) {for (int i = 0; i < 10; i++) {std::cout << "Worker " << index << " begins" << std::endl;std::this_thread::sleep_for(std::chrono::milliseconds(50));std::cout << "Worker " << index << " ends" << std::endl;std::this_thread::sleep_for(std::chrono::milliseconds(1));}
}int main() {std::thread worker1(worker, 1);std::thread worker2(worker, 2);worker1.join();worker2.join();std::cout << "Done" << std::endl;
}
