Latexmk does not generate the output PDF with XeLaTeX and biber when an output directory is specified.
I am using an output directory specified by -outdir called build to keep my root directory tidy.
I am running MikTeX on Windows 7 x64. Latexmk is version 4.54c.
Here is an MWE.
test.tex contains the following:
\documentclass{article}
\usepackage[backend=biber]{biblatex}
\addbibresource{publications.bib}
\begin{document}
\fullcite{InterestingArticle}
\end{document}
publications.bib contains the following:
@article{InterestingArticle,
author = {Andrew Bate},
title = {Interesting Article Title},
journal = {Interesting Journal},
volume = {999},
year = {1984}
}
When I run latexmk -xelatex -silent -outdir=build I get the following output, but no PDF in the build directory:
Use of uninitialized value $separator in regexp compilation at C:\Program Files\MiKTeX 2.9\scripts\latexmk\latexmk.pl line 8553.

Latexmk: Use the -f option to force complete processing,
unless error was exceeding maximum runs of latex/pdflatex.
Removing the -silent flag makes no difference (but obviously the output is longer).
If the -outdir flag is removed, then the PDF is generated correctly (but I would like to use an output directory).
The above example works correctly running on Linux (Ubuntu 17.10) with TeX Live and with latexmk version 4.54c (the same version of latexmk I used on Windows). On Linux, it works both with and without -outdir specified.
I am not using a .latexmkrc file.
Note the 'Use of uninitialized value' warnings. These don't appear on Linux, but I do not know if this is related.
Any help to get this working is greatly appreciated.
Update 2018-01-14: The issue only occurs when the source files are located in a directory on another computer on the network (e.g., a Windows mapped network drive).
The PDF is successfully generated when the source files are in a directory on the local filesystem.
Upgrading from version 4.54c to 4.54d (released 10 January 2018) removes some of the 'Use of uninitialized value' warnings, but the PDF file is still not generated when the source files are located in a network directory. I have filed a bug with John Collins, the author of latexmk.
$search_path_separatorseems to be the path separator (;under Windows and:on Unix-like systems). As far as I can tell, it's initialised in the operating system checks except in theelsif ( $^O eq "msys" )block. My guess is that perhaps you're runninglatexmkusing MSYS, and the separator variable isn't being set, which is breaking the path search.latexmk's maintainer. The$search_path_separatorvariable isn't being set in theelsif ( $^O eq "msys" )block which is the cause of theUse of uninitialized valuewarnings. Since this variable is related to the search path I'm guessing that may be the cause of the failure to find the files, but it's possible there may be something else as well. (Presumably you have an MSYS version of Perl, but I don't know enough about Windows to give further details.)
