Я где-то читал, что ошибка может быть вызвана прямым использованием #include для. cpp файлов, что делается в последних двух заголовочных файлах, поэтому я попытался скопировать содержимое файлов. cpp и поместить его вместо #include, и я все еще получаю ту же ошибку.

Кто-нибудь знает, что здесь делать?
