Hi,
I'm trying to define an enum_range and I based my implementation on the one from irange.
While writing my test I started just by checking that my enum_range satisfied the RandomAccessRangeConcept requirements and there were some errors with BidirectionalRangeConcept. I replaced by the result type of the irange function and the errors appear also there.
It seems that there is an issue concerning the category tags
..\..\../boost/concept_check.hpp:212:13: error: conversion from
'boost::detail::iterator_category_with_traversal<std::input_iterator_tag, boost::random_access_traversal_tag>' to non-scalar type 'std::bidirectional_iterator_tag' requested
Am I missing something?
You are almost certainly not missing anything. I have to look at some other iterator traversal category related issues particularly with the demotion of tags. I think there are some interoperability issues in this area. I need to make some time to review these issues, and put in new test cases. I'm a bit snowed under at work, but will try and get something done quickly. This issue is clearly affecting a few people now.
Best, Vicente
Thanks for the report, Neil Groves
