使用boost的log，用以下链接选项：
-lboost_system -lboost_thread -lboost_log -lboost_log_setup -lboost_filesystem -lpthread
当使用add_console_log函数编译链接时报错：

链接选项再加三个如下：
-lboost_system -lboost_thread -lboost_log -lboost_log_setup -lboost_filesystem -lpthread -lboost_locale -lboost_log -lboost_log_setup
编译正常通过了
最后发现下面三个库必须是这个顺序：
-lboost_log_setup -lboost_locale -lboost_log
中间可以穿插其它库，但是这三个的先后次序必须是这样的
