Hi All,<br><br>I am having an issue with the epstopdf tool, on TexLive 2008 on both Mac OS X and Windows. If I use GraphViz to generate a postscript file, epstopdf will fail to convert it to a PDF file with a Ghostscript stack trace, as such:<br>
<br><span style="font-family: courier new,monospace;">acheron:graphviz jholewinski$ epstopdf graph.eps<br>Error: /undefined in or:</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">Operand stack:</span><br style="font-family: courier new,monospace;">

<br><br>Does anyone know what causes this, or what the solution is? The graphs in question are being generated and converted by Doxygen, so I have no control over how epstopdf is being invoked and cannot simply use this two step process. I read of some related issues related to line endings, but changing the line endings to CR, LR, or CRLF does not help in this case. The issue is also not specific to Doxygen. The same error occurs with a simple GraphViz graph:<br>
