boost asio 示例测试失败

Question

我在 fedora xfce 上运行了一个简单的 boost asio 示例……它给出了这些错误……知道吗？

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

int main( int argc, char * argv[] )
{
    boost::asio::io_service io_service;

    io_service.run();

    std::cout << "Do you reckon this line displays?" << std::endl;

    return 0;
}

输出：

您需要链接到libboost_system，例如c++ you-file.cxx -lboost_system
