我正在编写我的论文，其中有一个根文件，每个章节都用 \include{chapterfolder/chaptername} 读入。一切正常，但参考文献都是未定义的。但是当我运行 BibTex 时，该过程顺利完成，没有错误（“过程正常退出”）。
我尝试将所有内容（即 chaptername.tex 和 chapterbibfile.bib）放在与根文件相同的文件夹中而不是子文件夹中，但结果是一样的。
奇怪的是，我有一个用于研究提案的旧版本，其中引用有效（恰好 2 年前）。我在 MacBook Pro 上使用 TeXLive-2015。
非常感谢您的帮助，谢谢。
这是我的根文件：

% the latter two are due to the "no-room-for-a-new-dimen" problem, which is discussed and resolved here: http://tex.stackexchange.com/questions/38607/no-room-for-a-new-dimen
% in my case, I had too many packages, and these two lines solve the trick
