UPDATE – 07/25/2019:

As noted in the comment below by @OleThomsenBuus (thank you!), from Boost 1.69 onward, Boost.System is now header-only, so there's no need to jump through all these hoops to eliminate the need to link with it.

ORIGINAL ANSWER:

The accepted answer is 100% effective and recommended, but another option—if you really want/need to use Boost Asio—is to try compiling your application with -DBOOST_ERROR_CODE_HEADER_ONLY. Use of this macro (documented here) should get around the need to link with Boost.System. However, it's worth reading the caveats pointed out in this answer. In particular, you may need to create a 'dummy' CPP file containing:

#define BOOST_ERROR_CODE_HEADER_ONLY
#include 

and disable optimization for that file only. (Personally, I didn't need to do this, but YMMV...)
