I have an issue similar to this one. In oppose to that thread, I use xelatex. Don't know, though, if this is the issue or not. I have two files. In the first one (Characteristics.tex) I have:

% Language specific stuff
\usepackage[cm-default]{fontspec}
\defaultfontfeatures{Ligatures=TeX}
\setmainfont{Times New Roman}
\newfontfamily\cyrillicfont{Times New Roman}
\usepackage{polyglossia}
\setdefaultlanguage{russian}
\setotherlanguage{english}

% Cross-referencing stuff
\usepackage{hyperref}
\usepackage{nameref}
\usepackage{zref-xr,zref-user}
\zexternaldocument*{Names}

Similarly in the second one (Names.tex):

% Language specific stuff
\usepackage[cm-default]{fontspec}
\defaultfontfeatures{Ligatures=TeX}
\setmainfont{Times New Roman}
\newfontfamily\cyrillicfont{Times New Roman}
\usepackage{polyglossia}
\setdefaultlanguage{russian}
\setotherlanguage{english}

% Cross-referencing stuff
\usepackage{hyperref}
\usepackage{nameref}
\usepackage{zref-xr,zref-user}
\zexternaldocument*{Characteristics}

Actually, it is only second file that contains references to the first file so far. So when I compile it with xelatex I get

Package zref-xr Warning: File `Characteristics.aux' not found or empty

that results into

LaTeX Warning: There were undefined references.

I have checked, the .aux file exists and is not empty. In case this is important, I use \label{} to indicate the label (only in Characteristics.tex so far) and \ref{},\zref{} or \nameref{} to call the reference. These work perfect in the same file, but do not work for cross-referencing between two files. Does anyone know how to resolve the issue?

Does the file exist in a directory in the tex input path? such as the current directory? –  David Carlisle Jun 27 '13 at 13:21
    
Yes, all files are in the same directory. –  Eugene B Jun 27 '13 at 13:44

Well if \input doesn't find the aux then it is not in the current directory. Check the spelling. –  Ulrike Fischer Jun 27 '13 at 15:46

Banged head in the wall. It was all about spelling! Thank you very much! –  Eugene B Jun 27 '13 at 16:04
