6103,boost::range_detail vs. boost::range::range_detail compiler error,zeratul976@…,Neil Groves,"The following code:


{{{
#include <boost/range/algorithm/search_n.hpp>
#include <boost/range/join.hpp>
}}}

Produces the following compiler errors:

{{{
boost/range/join.hpp:44:39: error: expected template-name before '<' token
boost/range/join.hpp:44:39: error: expected '{' before '<' token
boost/range/join.hpp:44:39: error: expected unqualified-id before '<' token
}}}

The reason is that:
  * boost/range/algorithm/search_n.hpp introduces the namespace boost::range::range_detail
  * boost/range/join.hpp defines joined_type in boost::range_detail
  * boost/range/join.hpp then references range_detail::joined_type in boost::range, expecting it to resolve to boost::range_detail::joined_type, but due to the declaration in search_n.hpp, it resolves to boost::range::range_detail::joined_type (which does not exist)

This is easily fixable by fully qualifying boost::range_detail::joined_type in join.hpp, or by getting rid of the namespace boost::range::range_detail in search_n.hpp and using boost::range_detail instead.",Bugs,closed,To Be Determined,range,Boost 1.47.0,Problem,fixed,,
