當我使用“boost :: log :: add_file_log（）”函數時，“error ld返回1退出狀態”

Question

編碼：

#include <boost/log/support/date_time.hpp>
#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>


int main()
{
    boost::log::add_file_log(
       boost::log::keywords::auto_flush = true,
       boost::log::keywords::file_name = "log%Y-%m-%d_%H-%M-%S.%N.log",
       boost::log::keywords::rotation_size = 10 * 1024 * 1024,

       /*if delete here, the compiler was successful*/
       boost::log::keywords::format  = "[%TimeStamp%] (%Severity%) : %Message%",
       boost::log::keywords::min_free_space=3 * 1024 * 1024
       );
}

我嘗試編譯此代碼，但提示信息：“錯誤ld返回1退出狀態”。

如果我刪除boost::log::keywords::format = "[%TimeStamp%] (%Severity%) : %Message%",則可以成功編譯此代碼。

Answer 1

您需要構建並鏈接Boost日志庫才能使此代碼生效，請參閱http://www.boost.org/doc/libs/1_62_0/libs/log/doc/html/log/installation/config.html 。

Answer 2

當我添加-lboost_log_setup並重建項目時，此問題已得到解決。

所以，它應該是鏈接-lboost_system -lboost_thread -lboost_log -lpthread -lboost_log_setup
