BOOST_FUSION_DEFINE_STRUCT(
    (),
    foo,
    (std::string,                   a)
    (std::string,                   b)
    )

should be

BOOST_FUSION_DEFINE_STRUCT(
    BOOST_PP_EMPTY(),
    foo,
    (std::string,                   a)
    (std::string,                   b)
    )

. Other than that, you did not include <string> . I am pretty sure your
compiler did not find an adequate operator== for std::string. The
compiler should have printed an error though. Which one are you using?
