It won't link only if BOOST_NO_EXCEPTIONS is defined, and it _might be_
getting defined implicitly somewhere in config headers (e.g. line 47 in
"boost/config/compiler/gcc.hpp"). I'd check if that's the case:

    #include <boost/config.hpp>

    #if defined(BOOST_NO_EXCEPTIONS)
    #    error here!
    #endif
