Greetings,

I try to port a c++ project to a new environment with clang++-17, libcxx 17 and std=c++17 for x64 Linux. Also, I switched form boost 1.65 to 1.84. Now I start getting errors in boost itself:

/workspace/usr/include/boost/statechart/fifo_worker.hpp:55:45: error: template argument for template type parameter must be a type
   55 | template< class Allocator = std::allocator< none > >

As far as I know this has to do with deprecation of some variable type in allocator. Any ideas how I might fix this on short notice?

Regards
