Ошибка при установке PDFlib

после долгих поисков и тестирования классов и библиотек, которые генерировали бы PDF-файл из html, бросьте и оставьте использовать PDFlib, говоря, что это более эффективно, но, по крайней мере, я знаю, что должен поддержать сообщество.

Но я застрял в начале.

Я даю следующую команду для установки

pecl install pdflib

и это дает ошибку в конце:

Может ли кто-нибудь помочь мне рассказать, какой недостаток я устанавливаю или настраиваю?
