Re: [Boost-users] boost-spirit: need help with simple parser

FWIW, your issue can be reproduced with much shorted code:

<skip include> <skip Ipv4 definition>

namespace qi = boost::spirit::qi; qi::uint_parser octet; int main() { Ipv4 ip; std::string s = "1.2.3.4"; bool r = qi::parse(s.begin(), s.end(), octet >> '.' >> octet >> '.' >> octet >> '.' >> octet, ip); }

or even simpler: boost::tuple v; bool r = qi::parse(s.begin(), s.end(), octet >> '.' >> octet >> '.'

...

octet >> '.' >> octet, v);

while the following works correctly: boost::fusion::vector v; bool r = qi::parse(s.begin(), s.end(), octet >> '.' >> octet >> '.'

...

octet >> '.' >> octet, v);

So, the attribute gets converted to boost::tuple is some strange way...
