与升压未定义的引用，当我尝试编译 [英] undefined reference with boost when I try to compile

问题描述

我有很多的错误，当我尝试编译我与提高服务器。
在这里，这是我的makefile：

i have lot of errors when i try to compile my server with boost. Here, this is my makefile :

NAME    =       serveur

SRCS    =       Serveur/main.cpp                \

                Serveur/Commande.cpp            \
                Serveur/My_exception.cpp        \
                Serveur/Network.cpp             \
                Serveur/Server.cpp

在google搜索我发现，有必要把 -lboost_filesystem 但它没有再工作，旁边还有错误：

After "googling" i found that it's necessary to put -lboost_filesystem but it's not working again and there are next errors :

任何人都知道为什么它不工作？

Anyone know why it's not working?

推荐答案

的boost ::文件系统取决于的boost ::系统，所以你必须添加 -lboost_system ，也。

boost::filesystem depends on boost::system, so you'll have to add -lboost_system, also.
