Whenever I try to use the gnuplottex package, I get the following error messages:

/usr/share/texlive/texmf-dist/tex/latex/gnuplottex/gnuplottex.sty:79: Argument of " has an extra }. [...te\write18{rm -f "\jobname.gnuploterrors"}]
/usr/share/texlive/texmf-dist/tex/latex/gnuplottex/gnuplottex.sty:79: Paragraph ended before " was complete. [...te\write18{rm -f "\jobname.gnuploterrors"}]
/home/myDocument.tex:118: Package catchfile Error: File `myDocument.gnuploterrors' not found. [\end{document}]
TeX STOPPED: File ended while scanning use of \gnuploterrors@eatpa\ifx \gnuploterrors@ \@empty \else \PackageWarningNoLine {gnuplottex}
TeX reports the error was in file: myDocument.tex

Line 79 of gnuplottex.sty reads \immediate\write18{rm -f "\jobname.gnuploterrors"}, so it not being executed seems to be the cause for the other errors.

Everything worked fine before, but I upgraded to Xubuntu 16.04 LTS lately, so this may be the cause. I already tried removing gnuplot and TeX Live completly and installing them again, but the error remains.


I'm using pdflatex and Version 0.9.1 of gnuplottex. All it needs to produce this error is just a \usepackage{gnuplottex}, so for example this document doesn't compile:

%!TEX options = "--shell-escape"




However, I noticed that with this minimal file, only the last 3 lines of the error message from above are shown. All 5 lines are only shown if I also add \usepackage{ngerman}.

  • Can you add a minimal example of a LaTeX file for testing? Also the version of gnuplottex is needed. Are you running pdflatex or lualatex? – egreg Apr 23 '16 at 16:29
  • How do I find out my version of gnuplottex? – jmb Apr 23 '16 at 17:18
  • Look in the log file: you should find something like Package: gnuplottex 2015/12/13 v0.9.1 gnuplot graphs in LaTeX – egreg Apr 23 '16 at 17:20

It's an oversight of gnuplottex: if no gnuplot diagram is processed, the file <jobname>.gnuploterrors is not produced, so the final code for displaying errors fails to find it.

203 \AtEndDocument{%
204   \ifmiktex
205   \else
206     \CatchFileDef\gnuploterrors@{\jobname.gnuploterrors}{\endlinechar=`^^J \catcode`\ =12 }%
207     \expandafter\gnuploterrors@eatpar\gnuploterrors@\@nil
208     \ifx\gnuploterrors@\@empty\else
209       \PackageWarningNoLine{gnuplottex}{Gnuplot execution produced errors:^^J%
210         \detokenize\expandafter{\gnuploterrors@}}%
211     \fi
212   \fi
213 }

Lines 206–211 should better be

      \CatchFileDef\gnuploterrors@{\jobname.gnuploterrors}{\endlinechar=`^^J \catcode`\ =12 }%
        \PackageWarningNoLine{gnuplottex}{Gnuplot execution produced errors:^^J%

However, the error should not appear as soon as you have a gnuplot environment in your document.

  • Thank you a lot! Shouldn't this be considered a bug in gnuplottex? Also, shouldn't many more people be running in to this problem? I couldnt't find anything about it online. – jmb Apr 23 '16 at 18:25
  • @jmb Possibly nobody tried using the package with no gnuplot environment in the document. But it's surely something to be solved. – egreg Apr 23 '16 at 19:22

    @jmb It's silly to unaccept the answer that solves the stated problem. If you have different problems, you should state them clearly. – egreg Jun 23 '16 at 12:36

    Thanks for the fix! @jmb I've just uploaded a new version, which should be available shortly. Please use the github project page for reporting bugs. – Lars Kotthoff Aug 21 '16 at 19:57
