c++ - 如何将 boost 库链接到我的项目？

Question

我已经写好了代码

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

using namespace std;

void f1()
{
    cout <<"Hello world, I'm a thread1!"<<endl;
}

int main()
{
    boost::thread t1(&f1);
return 0;
}

并在qt creator中添加pro文件中的字符串

LIBS += -L/usr/lib/x86_64-linux-gnu -lboost_system

我遇到了这些错误

build-test_not_qt_1-Desktop-Debug/main.o:-1: In function boost::detail::thread_data_base::thread_data_base()':

我该如何修复它们？以及如何使应用程序运行？
