# Using package todonotes and auto-pst-pdf does not work

I need auto-pst-pdf so the package chemnum automatically number the chemicals I use in figueres. But I run into the problem that if I use the package todonotes at the same time my TexShop stops working.

So I use this example.

% !TEX encoding = UTF-8 Unicode
\documentclass[
a4paper,                       %% DIN A4-Papier
DIV=calc,                       %% Satzspiegel berechnen
11pt,                          %% Schriftgröße
english
]{scrreprt}                    %% KOMA-Skript Report als Klasse

\usepackage[colorinlistoftodos,prependcaption]{todonotes}       %%ToDo-Notes.
\usepackage{chemnum}              %% Numbering chemical compounds
\usepackage{auto-pst-pdf}         %% needed for replacing temporary strings to numbers

\begin{document}
\listoftodos

Bla blub
\todo{Deckblatt designen}

\begin{figure}
\centering
\replacecmpd{cmpd:1}
\replacecmpd{cmpd:2}
\replacecmpd{cmpd:3}
\includegraphics[width=1\textwidth]{ChemDraw/CHI-014-CD15.eps}
\end{figure}

\end{document}


If I either comment out all todonotes or auto-pst-pdf everything works fine (except that I have no todo notes or my temporary strings don't get replaced of course)

After this output the TexShop stops working.

This is the complete .log fiile

Can anybody present me a solution for this problem?

• If you get an error please always show the exact error from the log. I ran your example with pdflatex --shell-escape (but using example-image as the image) and it ran with no errors although of course none of the replacements matches in that case. – David Carlisle May 25 '17 at 8:35
• It is best to show the log as tex (in a code section) rather than as an image, but the image that you show shows no error (the pdf special warning is just a feature of auto-pst-pdf) – David Carlisle May 25 '17 at 8:47
• That's what I was wondering about too. I don't get an error, TexShop just crashes... Maybe the problem lies with TexShop and not the used packages? The created PDF File makes Preview Stop working after some time and I can't open up my .tex file with TexShop until I delete the .pdf file beforehand – Christoph H. May 25 '17 at 8:48
• how can the editor crash just running tex, that's odd, what happens if you just run pdflatex --shell-escape your file on the commandline? – David Carlisle May 25 '17 at 8:52
• Using the command line like you suggested works fine. Still Preview crashes after 20 seconds or so, so something's still not working alright. – Christoph H. May 25 '17 at 8:54
