When I'm trying to build upstream i2pd, which uses Boost ASIO using g++ with C++20 enabled (https://github.com/PurpleI2P/i2pd/commit/a6f9a56e40a40f5a9d153e701a067c5251669ac4), g++ throws error: g++ -g -O2 -ffile-prefix-map=/github/workspace=. -fstack-protector-strong -Wformat -Werror=format-security -Wall -pedantic -std=c++20 -fPIC -DUSE_UPNP -D__AES__ -maes -MMD -MP -Ilibi2pd -Ilibi2pd_client -Ii18n -DOPENSSL_SUPPRESS_DEPRECATED -c -o obj/libi2pd/Crypto.o libi2pd/Crypto.cpp In file included from /usr/include/boost/asio.hpp:23, from libi2pd/Timestamp.h:16, from libi2pd/TunnelBase.h:14, from libi2pd/Crypto.cpp:17: /usr/include/boost/asio/awaitable.hpp: In constructor ‘boost::asio::awaitable<T, Executor>::awaitable(boost::asio::awaitable<T, Executor>&&)’: /usr/include/boost/asio/awaitable.hpp:68:19: error: ‘exchange’ is not a member of ‘std’; did you mean ‘std::__atomic_impl::exchange’? 68 | : frame_(std::exchange(other.frame_, nullptr)) | ^~~~~~~~ In file included from /usr/include/c++/12/bits/shared_ptr_atomic.h:33, from /usr/include/c++/12/memory:78, from libi2pd/Crypto.cpp:13: /usr/include/c++/12/bits/atomic_base.h:976:7: note: ‘std::__atomic_impl::exchange’ declared here 976 | exchange(_Tp* __ptr, _Val<_Tp> __desired, memory_order __m) noexcept | ^~~~~~~~ Looks like boost is using deprecated or removed C++20 functions.
