我正在尝试使用breakurl包来打破长 URL，因此它会绕行，因为它会弄乱我的表格的对齐方式。问题是我不断收到消息
Package breakurl Warning: You are using breakurl while processing via pdflatex.
(breakurl) \burl will be just a synonym of \url.
(breakurl) on input line 48.
即使文件是用 lualatex 编译的。我按照显示的答案如何打破项目中的长 URL我之前从未使用过这个包，所以我可能做错了什么，但到目前为止我还没有发现。
这是 MWE
\documentclass[11pt]{article}%
\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\usepackage[hyphenbreaks]{breakurl}
\begin{document}
\burl{http://www.google.com}%same error with \url
\end{document}
现在
lualatex foo.tex
This is LuaTeX, Version beta-0.80.0 (TeX Live 2015) (rev 5238)
(/usr/local/texlive/2015/texmf-dist/tex/latex/url/url.sty))

Package breakurl Warning: You are using breakurl while processing via pdflatex.

我的问题是，为什么命令是 lualatex，却显示使用 pdflatex？我需要做什么才能消除这个错误？

答案1
Luatex 0.80 与 pdflatex 兼容，因此对于大多数特定于驱动程序的功能使用相同的后端文件。正如您的日志所示：
(/usr/local/texlive/2015/texmf-dist/tex/latex/hyperref/hpdftex.def
使用pdftex hyperef文件。
为了避免出现警告，只需不要使用该包，对于 pdftex 或 luatex 来说，它是没有必要的，而且也没有什么用处。
对于 luatex，您还应该避免使用 inputenc 和 fontenc 包。
