#6103: boost::range_detail vs. boost::range::range_detail compiler error
------------------------------------+---------------------------------------
Reporter: zeratul976@⦠| Owner: neilgroves
Type: Bugs | Status: new
Milestone: To Be Determined | Component: range
Version: Boost 1.47.0 | Severity: Problem
Keywords: |
------------------------------------+---------------------------------------
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.
