Hi, I was trying to use the tokeniser lib and encountered this error: "/home/patwarta/boost_1_28_0/boost/iterator_adaptors.hpp", line 819: Error: The base "boost::detail::iterator_adaptor_traits_gen<boost::detail::token_ iterator_base<const char*>, std::basic_string<char, std::char_traits<char>, std::allocator<char>>, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>&, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>*, std::forward_iterator_tag, int>::type" must be a previously defined class or struct. "XMLbParserWrapper.cxx", line 11: Where: While specializing "boost::iterator_adaptor<boost::detail::token_iterator_ba se<const char*>, boost::detail::tokenizer_policy<std::basic_string<char, std::char_traits<char>, std::allocator<char>>, boost::char_delimiters_separator<char, std::char_traits<char>>>, std::basic_string<char, std::char_traits<char>, std::allocator<char>>, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>&, const std::basic_string<char, std::char_traits<char>, std::allocator<char>>*, std::forward_iterator_tag, int> Any ideas? Thanks in advance, Tanmay
