我试图编译程序，它在Ubuntu上使用Boost库和我得到的错误：链接错误，同时连接升压日志（未定义的引用，以提高::登录:: v2_mt_posix ::汇）

我尝试这样做：
g++ -std=c++11 -Wall -pedantic -g -O0 -DBOOST_LOG_DYN_LINK -c test.cpp
g++ test.o -lboost_log -lboost_thread -lpthread -lboost_system -lboost_log_setup -o test
这：
g++ -DBOOST_LOG_DYN_LINK test.cpp -Wall -L$BOOST/lib/ -I $BOOST/include/ -pthread -lboost_system -lboost_log_setup -lboost_log -lboost_date_time -lboost_thread -lrt -lboost_filesystem
从应对这些问题：
linker error while linking boost log tutorial (undefined references)
Boost.Log linking errors under GNU/Linux
没有成功 - 联和错误信息时相同的错误看起来比略有不同以上问题
因此，我认为我的错误的根本原因是从上面
安装增压版本1.58
