Question

我已经写了代码

#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

中的pro文件中添加了字符串

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

我发现了这些错误

build-test_not_qt_1-Desktop-Debug / main.o：-1：在函数boost::detail::thread_data_base::thread_data_base()': /build-test_not_qt_1-Desktop-Debug/main.o:-1: In function boost :: detail :: thread_data_base :: thread_data_base（）＆＃39;： build-test_not_qt_1-Desktop-Debug / main.o：-1：在函数boost::thread::start_thread()': build-test_not_qt_1-Desktop-Debug/main.o:-1: In function boost :: thread :: start_thread（）＆＃39;： build-test_not_qt_1-Desktop-Debug / main.o：-1：在函数boost::thread::~thread()': build-test_not_qt_1-Desktop-Debug/main.o:-1: In function boost :: thread ::〜thread（）＆＃39;： build-test_not_qt_1-Desktop-Debug / main.o：-1：在函数boost::detail::thread_data<void (*)()>::~thread_data()': /usr/include/boost/thread/detail/thread.hpp:91: error: undefined reference to boost :: detail :: thread_data_base :: ~thread_data_base（）＆＃39; （.rodata._ZTIN5boost6detail11thread_dataIPFvvEEE [_ZTIN5boost6detail11thread_dataIPFvvEEE] + 0x10）： - 1：错误：未定义引用`typeinfo for boost :: detail :: thread_data_base＆＃39; ：-1：错误：collect2：错误：ld返回1退出状态

我该如何修复它们？以及如何使应用程序正常工作？

$string = '3-1-0-1.11,3-1-1-1.12,3-1-2-1.13,3-1-3-1.14,3-2-0-1.02,3-2-1-1.03,3-2-2-1.04,3-2-3-1.05,3-2-4-1.06,3-3-0-3.23,3-3-1-3.24,3-3-2-3.25,3-3-3-3.26';

foreach(explode(',', $string) as $tpl) {
    $tpl = explode('-', $tpl);
    $tpl[3] = explode('.', $tpl[3]);
    $result[$tpl[1]][$tpl[2]][$tpl[3][0]] = !empty($tpl[3][1]) ? $tpl[3][1] : null;
}
var_dump($result);

如何将boost库链接到我的项目？
