[Boost-users] [spirit] warnings after upgrade to 1.47

Dear all, After upgrading to boost 1.47, I got the attached enormous warning, ironically saying that names are too long, for a very simple use of boost.spirit. Code: #include <string> #include <vector> using namespace std; #include namespace bsk = boost::spirit::karma; namespace bsa = boost::spirit::ascii; vector<string> vUnrecog; //... bsk::generate(ostream_iterator<char>(cout), "Init file options not recognized:\n" << (" \"" << bsa::string << '"' << bsk::eol) % "", vUnrecog); Is there something I am doing suboptimally or in an old way? (The code has been around for about 2 years now). Thanks and best, Dee
