Re: [Boost-users] Noob question - undefined reference to boost::system::get_system_category

You need to *link* the system library. For example, it might be called libboost_system-gcc43-mt-1_37.so.

See Steven's response which pointed you toward the Getting Started guide.

Alternatively it's possible to use the non-boost asio, which is header-only: http://blog.think-async.com/2008/05/boostasio-vs-asio.html
