Hi All,
I am trying to use boost json_parser. I have included json_parser.hpp in my
cpp file, I have not included any other code. But I am getting many
compilation  errors  like error: 'boost::spirit::classic' has not been
declared and
In function void
boost::property_tree::json_parser::read_json_internal(std::basic_istream<typename
Ptree::key_type::value_type, std::char_traits<typename
Ptree::key_type::value_type> >&, Ptree&, const std::string&):
     [exec]
/usr/include/boost/property_tree/detail/json_parser_read.hpp:288: error:
\u2018classic\u2019 is not a namespace-name

Can you help me resolve this issue?
