I have successfully built the libraries using GCC master with cxxstd=11,14,17,20,23 on x86_64 Ubuntu 23.04. Matt

Looks good on Windows/Visual Studio for 10.0 - 14.3. toolset arch compile Link Execute msvc-10.0 32 X X X msvc-10.0 64 X X X msvc-11.0 32 X X X msvc-11.0 64 X X X msvc-12.0 32 X X X msvc-12.0 64 X X X msvc-14.0 32 X X X msvc-14.0 64 X X X msvc-14.1 32 X X X msvc-14.1 64 X X X msvc-14.2 32 X X X msvc-14.2 64 X X X msvc-14.3 32 X X X msvc-14.3 64 X X X Compile means that the b2 command completed without errors Link means that visual studio was able to link a sample executable to a library (libboost_thread-vcXXX-mt[-gd]-1_XX.lib) generated Execute means that the linked program executed without errors.

Sorry for the very late report, but I think I found a serious regression in either Boost.Stl_interfaces or in Boost.Range. Some iterators generated by Boost.Stl_interfaces are not accepted by Boost.Range. This is a regression from Boost 1.82. Minimal example program, with basic_input_iter taken directly from a Boost.Stl_interfaces test: #include "boost/stl_interfaces/iterator_interface.hpp" #include "boost/range/iterator_range.hpp" struct basic_input_iter : boost::stl_interfaces::iterator_interface< #if !BOOST_STL_INTERFACES_USE_DEDUCED_THIS basic_input_iter, #endif std::input_iterator_tag, int> { basic_input_iter() : it_(nullptr) {} basic_input_iter(int * it) : it_(it) {} int & operator*() const noexcept { return *it_; } basic_input_iter & operator++() noexcept { ++it_; return *this; } friend bool operator==(basic_input_iter lhs, basic_input_iter rhs) noexcept { return lhs.it_ == rhs.it_; } using base_type = boost::stl_interfaces::iterator_interface< #if !BOOST_STL_INTERFACES_USE_DEDUCED_THIS basic_input_iter, #endif std::input_iterator_tag, int>; using base_type::operator++; private: int * it_; }; auto make_range() { static int si; return boost::make_iterator_range( basic_input_iter(&si), basic_input_iter(&si + 1)); } This fails to compile with the following errors:
