我通过yum在Fedora20上安装了Boost，并尝试了一些简单的例子。但是，我很难从logging tutorial中编译第一个示例。
用g++ -c boosttest.cc编译很好，但是当我尝试将其链接到
g++ boosttest.o -o boosttest -lboost_log -lpthread

我错过了什么？我做错什么了？
编辑1:输出的顺序没有区别。也有，但解决方案不适用于我。以下操作也会因同样的错误而失败：
g++ -DBOOST_LOG_DYN_LINK boosttest.o -o boosttest -lboost_log -lpthread
最佳答案：
只需添加一行
#define BOOST_LOG_DYN_LINK 1
作为
boosttest.cc的第一行。或者，您可以将
-DBOOST_LOG_DYN_LINK添加到编译步骤（而不是链接步骤，正如您在问题中发布的那样）：g++ -std=c++11 -Wall -pedantic -g -O0 -DBOOST_LOG_DYN_LINK -c boosttest.cc
g++ boosttest.o -lpthread -lboost_log -o boosttest
