I was able to successfully build the libraries on Mac OS 10.15 using: Apple clang version 11.0.3 (clang-1103.0.32.62) using C++03/11/14/17/2a And with a recent ToT clang using C++03/11/14/17/2a — Marshall

Does boost have a mechanism (compilation flags, auto-defined macro, etc.) to mask `std::auto_ptr` usage ? Note that the situation isn't quite as simple as replacing library-internal use of `std::auto_ptr`. For example, in case of Boost.Python we also need to specialize templates so users can continue using `std::auto_ptr` in their own code, unless they explicitly (using macros) or implicitly (using modern compilers) disable such backward-compatible support. I suppose there are other Boost libraries in a similar situation. Thanks, Stefan -- ...ich hab' noch einen Koffer in Berlin...

Here's a sample of the warnings -- looks to me like the python case all the warnings come from detail - so for modes past c++11 I'd think unique_ptr could be used. A macro for python could allow users to override the removal and use auto_ptr in their code if they choose. And this problem is isolated to python and locale. ./boost/locale/localization_backend.hpp:116:59: warning: ‘template<class> class std::auto_ptr’ is deprecated [-Wdeprecated-declarations] ./boost/locale/util.hpp:180:28: warning: ‘template<class> class std::auto_ptr’ is deprecated [-Wdeprecated-declarations] ./boost/python/detail/is_auto_ptr.hpp:17:40: warning: ‘template<class> class std::auto_ptr’ is deprecated [-Wdeprecated-declarations] ./boost/python/detail/is_auto_ptr.hpp:17:40: warning: ‘template<class> class std::auto_ptr’ is deprecated [-Wdeprecated-declarations] Jeff

Note that the usage in Boost.Python is already wrapped in `# if !defined(BOOST_NO_AUTO_PTR)` so in principle that code shouldn't be visible in C++14 and beyond. Hence my question. I'll investigate. Thanks, Stefan -- ...ich hab' noch einen Koffer in Berlin...

You're right -- it looks like the logic is there. Maybe the is_auto_ptr.hpp just doesn't have it in the include path (it isn't there directly). config/libstdcpp3.hpp // std::auto_ptr isn't provided with _GLIBCXX_DEPRECATED=0 (GCC 4.5 and earlier) // or _GLIBCXX_USE_DEPRECATED=0 (GCC 4.6 and later). #if defined(BOOST_LIBSTDCXX11) # if BOOST_LIBSTDCXX_VERSION < 40600 # if !_GLIBCXX_DEPRECATED # define BOOST_NO_AUTO_PTR # endif # elif !_GLIBCXX_USE_DEPRECATED # define BOOST_NO_AUTO_PTR # endif #endif Jeff

config/libstdcpp3.hpp

btw I did this experiment and it didn't work so something else non obvious is happening. Jeff

Those boost headers could use: #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wdeprecated-declarations" ... #pragma GCC diagnostic pop around the uses of auto_ptr. That will prevent warnings coming from those uses. If users use auto_ptr in their own code then surely those users should be responsible for disabling the warnings coming from their own code? If you use the pragmas above then they won't get warnings from the Boost headers, even if they pass their auto_ptr objects to the Boost functions. They'd only get warnings for their own uses of auto_ptr in their own code, which as I said, is their concern not Boost's.

There's a fix for the warning in Boost.Coroutine, merged to master - is it possible to include this in the release? See: https://github.com/boostorg/coroutine/pull/55 Thanks
