“架构x86_64的未定义符号：” Boost 1.73.0 Clion MacOS

问题描述

我是C ++的超级新手，刚开始涉足Boost C ++库

我目前在MacOS Catalina上，并使用CLion作为我的c ++ IDE。

我使用自制软件brew install boost

安装了boost

我正在关注以下的一些教程：http://antonym.org/2009/05/threading-with-boost-part-i-creating-threads.html了解boost::thread

代码如下：

#include <iostream>
#include <boost/thread.hpp>
#include <boost/date_time.hpp>


void workerFunc()
{
    boost::posix_time::seconds workTime(3);
    std::cout << "Worker: running" << std::endl;
    // Pretend to do something useful...
    boost::this_thread::sleep(workTime);
    std::cout << "Worker: finished" << std::endl;
}


int main(int argc,char* argv[])
{
    std::cout << "main: startup" << std::endl;
    boost::thread workerThread(workerFunc);
    std::cout << "main: waiting for thread" << std::endl;
    workerThread.join();
    std::cout << "main: done" << std::endl;
    return 0;
}

这是我的CMakeLists.txt文件

cmake_minimum_required(VERSION 3.17)
project(cpp_boost)

set(CMAKE_CXX_STANDARD 14)

find_package(Boost 1.73.0 COMPONENTS system filesystem REQUIRED)
include_directories(${Boost_INCLUDE_DIRS})

add_executable(${PROJECT_NAME} main.cpp)

target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES})

最后，我在运行代码时遇到的构建错误。

我试图浏览互联网，但找不到任何具体内容。我发现它对target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES})很有用，但是将其添加到CMakeLists.txt文件后，错误仍然存​​在。

任何帮助将不胜感激。

谢谢：）

解决方法

谢谢一些程序员花花公子

它只是向find_package添加thread使其起作用

这是更新的CMakeLists.txt

cmake_minimum_required(VERSION 3.17)
project(cpp_boost)

set(CMAKE_CXX_STANDARD 14)

find_package(Boost 1.73.0 COMPONENTS system filesystem thread REQUIRED)
include_directories(${Boost_INCLUDE_DIRS})

add_executable(${PROJECT_NAME} main.cpp)

target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES})
