re：question about compile the boost head file.
Respeced Mr.Emil, Thank you for your kindly reply.
I can't reproduce this with msvc versions available on godbolt:
https://godbolt.org/z/E8vYWTPf6 Exactly on godbolt,the compilers work well. I test this by myself. Once again, I change to the Microsoft Visual Studio Community 2019 ver. 16.11.18. And compile the program ,the error still exist.
Can you provide a complete error log, including source file and line of the
error?

Can you write a simple program that demonstrates the problem on godbolt.org? Looking at the source code, I don't understand why the error_info_container class would be abstract.
