C++ Mac OS和QtCreator（G+；+；）上的Boost Log 1.54

如何使用1.54版Boost中的日志库？（我正在使用QtCreator，并已成功使用boost/filesystem）

我读到日志库现在是Boost的一部分，但我无法让它在MacOs上工作：

我的

您是否构建了Boost.Log？它是否显示在链接器搜索路径上？请注意，它由两个lib组成：

libboost\u log

和

libboost\u log\u安装程序

。我通过

brew安装Boost安装了Boost，lib被附加到路径。是否需要安装其他软件？“ld:symbol未找到架构x86_64”-您安装了什么版本的boost？编译程序时，请尝试添加-m32标志。看起来您正在尝试链接x86 libs
