Hi, I’m trying to build Boost.Graph and running into missing header files that used to live in boost/detail and now live elsewhere. Here’s a couple of examples of headers that moved and the code that still expects to find them there: detail/container_fwd.hpp libs/functional/include/boost/functional/hash/extensions.hpp: #include libs/lambda/include/boost/lambda/detail/operator_return_type_traits.hpp: #include "boost/detail/container_fwd.hpp" libs/phoenix/include/boost/phoenix/stl/algorithm/detail/is_std_list.hpp: #include libs/phoenix/include/boost/phoenix/stl/algorithm/detail/is_std_map.hpp: #include libs/phoenix/include/boost/phoenix/stl/algorithm/detail/is_std_set.hpp: #include detail/indirect_traits.hpp libs/iterator/include/boost/iterator/detail/facade_iterator_category.hpp: #include libs/iterator/include/boost/iterator/indirect_iterator.hpp: #include It seems that indirect_traits.hpp was moved from detail into python/detail, and container_fwd.hpp into container. Just curious but was it intentional to make many Boost libraries depend on Python through boost/iterator/iterator_facade.hpp? Noel
