Boost Log record_ostream.hpp 不会编译

问题描述

我正在尝试为 Boost Log 编译示例代码。我收到编译器错误，并假设它与我的编译器标志有关，但我不确定。我的 main.cpp 文件中的代码（直接从教程示例中复制）如下所示：

/*
 * main.cpp
 *
 *  Created on: Apr 16,2021
 *      Author: ubuntu
 */

#include <boost/log/core.hpp>
#include <boost/log/trivial.hpp>
#include <boost/log/expressions.hpp>
#include <boost/log/sinks/text_file_backend.hpp>
#include <boost/log/utility/setup/file.hpp>
#include <boost/log/utility/setup/common_attributes.hpp>
#include <boost/log/sources/severity_logger.hpp>
#include <boost/log/sources/record_ostream.hpp>

namespace logging = boost::log;
namespace src = boost::log::sources;
namespace sinks = boost::log::sinks;
namespace keywords = boost::log::keywords;

void init()
{
    logging::add_file_log("sample.log");

    logging::core::get()->set_filter
    (
        logging::trivial::severity >= logging::trivial::info
    );
}

int main()
{
    init();
    logging::add_common_attributes();

    using namespace logging::trivial;
    src::severity_logger< severity_level > lg;

    BOOST_LOG_SEV(lg,trace) << "A trace severity message";
    BOOST_LOG_SEV(lg,debug) << "A debug severity message";
    BOOST_LOG_SEV(lg,info) << "An informational severity message";
    BOOST_LOG_SEV(lg,warning) << "A warning severity message";
    BOOST_LOG_SEV(lg,error) << "An error severity message";
    BOOST_LOG_SEV(lg,fatal) << "A fatal severity message";

    return 0;
}

我在 Ubuntu 20.04 上从 Eclipse 编译，以下是我的编译器命令： g++ -std=c++0x -I/usr/local/boost_1_76_0 -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.o" -o "main.o" "../main.cpp"

编译器的输出如下所示（被截断为仅显示第一条错误消息）：

16:00:18 **** Incremental Build of configuration Debug for project Simserve ****

  556 |     for (::boost::log::record rec_var = (logger).open_record((BOOST_PP_SEQ_ENUM(params_seq))); !!rec_var;)\
      |     ^~~**

谁能告诉我我做错了什么？谢谢。
