Error using lualatex and tikzexternalize to compile document with PGFPlots

I have a fairly large document with a number of pgfplots diagrams and due to memory capacity limits in PDFLaTeX I am now using LuaLaTeX to compile. While this works well, it takes forever to produce the document, so I would like to externalise the compilation of the plots. I have tried different approaches, but none seem to work. When I try to compile a minimal example such as

%compiled using "../MiKTeX/miktex/bin/lualatex.exe" -enable-write18  %.tex
%using MiKTeX Portable, hence the ".../lualatex"

\documentclass[11pt]{minimal}

\usepackage{pgfplots}
\usepgfplotslibrary{external}
\tikzset{external/system call={"../MiKTeX/miktex/bin/lualatex.exe" -enable-write18 -halt-on-error -interaction=batchmode -jobname "\image" "\texsource"}}
\tikzexternalize

\pgfplotsset{compat=1.10}

\begin{document}

\begin{tikzpicture}
\begin{axis}[%
xlabel=x,
ylabel=y]
(2,-2)
(3,-3)
(4,-4)
(5,-5)
};
\end{axis}
\end{tikzpicture}

\end{document}


I get the following error:

===== 'mode=convert with system call': Invoking '"../MiKTeX/miktex/bin/lualatex.

file 'MWE-figure0' (expected one of .pdf:.jpg:.jpeg:.png:). Please verify that
you have enabled system calls. For pdflatex, this is 'pdflatex -shell-escape'.
Sometimes it is also named 'write 18' or something like that. Or maybe the comm

tinue now, I'll try to typeset the picture.


And nothing but an *.md5 file is produced. Can anybody tell me where I am mistaken? Thanks.

What does the log for the supplementary LaTeX run show? –  Joseph Wright Apr 3 '14 at 15:11
@JosephWright I have edited the error message to include the system call. Other than that I do not know which log you mean. The MWE-figure0.log is not produced. –  Chaplin Apr 3 '14 at 15:28

I got errors from the \pgfplotsset{compat=1.10} but my pgf in miktex isn't quite uptodate. When I changed it to \pgfplotsset{compat=1.9} and used simply lualatex instead of your longer executable it worked fine. –  Ulrike Fischer Apr 3 '14 at 15:29
So for me. With 1.10, too. –  LaRiFaRi Apr 3 '14 at 15:43

How did you compile your document.tex?

I turns out, that some latex editors do not add the -shell-escape when compiling. If you do not have it (in the command line, or the latex editor of your choice) try using lualatex -shell-escape document.tex.

For example, in TeXstudio or Texmaker the LuaLaTeX command has to be changed from

lualatex -synctex=1 -interaction=nonstopmode %.tex to

lualatex -shell-escape -synctex=1 -interaction=nonstopmode %.tex.

Welcome to TeX.sx! Based on the comments, the OP's editor is TeXmaker. –  T. Verron Apr 28 at 8:46
I just tested in in the portable version of TeXmaker and it is the same issue that can be resolved the same way. –  Christian A. Hans Apr 28 at 9:14
I can compile the document from the command line, if (and only if) the \tikzset` command is removed. Configuring TeXmaker (which is indeed my editor) to use the suggested command does not resolve the issue. While the former is related to the pgf external library, the latter is probably caused by the configuration of my system (i.e. the combination of portable editions of both TeXmaker and MikTeX). Hence, I have accepted the answer since the remaining issue was not the primary focus of the question... –  Chaplin Apr 29 at 16:26
