Невозможно скомпилировать boost-asio на MSVC, но только с помощью /std:c++20 и набора инструментов v143. ⇐ C++

[Anonymous]

Кажется, я не могу найти никакой информации об этой ошибке. Это моя очень простая программа повышения asio:

Код: Выделить всё

#include 
#include 

auto main() -> int
{
boost::asio::io_context ctx;
boost::asio::serial_port p(ctx);
return 0;
}
< /code>
Это не может компилировать для меня в Visual Studio 17.12.4 (самая новая), когда я использую оба /Std: C ++ 20 < /code> (или выше) и V143 Toolkit. Он работает как с инструментарием V142, так и с версией нижнего языка - только комбинация обоих не может построить. Моя версия Boost - 1.84.0.  Сообщение об ошибке: < /p>

Есть какие-нибудь подсказки?
