https://svn.boost.org/trac10/ticket/4642 <p> Some BGL headers like boost/graph/detail/adjacency_list.hpp include boost/pending/integer_range.hpp and use a class template boost::integer_range to represent a vertex/edge list. Since 1.44.0, however, Boost.Range supports a class template which has the same name and probably the same role in boost/range/irange.hpp; it didn't have integer_range and instead used boost::iterator_range&lt;boost::range_detail::integer_iterator&lt;Integer&gt; &gt; in 1.43.0. Therefore the following simple code causes compile errors using 1.44.0. </p> <pre class="wiki">// test.cpp #include &lt;boost/graph/adjacency_list.hpp&gt; #include &lt;boost/range/irange.hpp&gt; int main() { return 0; } </pre><p> The errors are as follows; </p> <pre class="wiki">$ g++ --version g++ (Ubuntu 4.4.3-4ubuntu5) 4.4.3 Copyright (C) 2009 Free Software Foundation, Inc.
