I have read many answers here, but nothing work. I have an error in my lyx with eps to pdf conversion. when I use epstopdf in terminal it works, but with lyx doesn't work. this is my latex code:

    %% LyX 2.1.2 created this file.  For more info, see http://www.lyx.org/.
%% Do not edit unless you really know what you are doing.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% User specified LaTeX commands.

















this is the error message:

    Package epstopdf Info: Source file: <image.eps>(epstopdf)

See the pdftex.def package documentation for explanation.
Type  H <return>  for immediate help.    

what is the problem

  • Welcome to TeX-sx. We will need to see an example file here: as you are using LyX, what we ideally want is the exported LaTeX. The most usual cause of errors of this type is using the file extension in the name of the graphic, but that may not be it. Do you actually get the converted PDF files created?

  • @Seitz You can edit your post at any time, so it's better to edit it and put the code directly there. As well, if you select the new code and click the {} button above the edit window, the code will be properly formatted ;)

  • Well if it works on the terminal, why don't you simply convert your graphics to pdf before use and includes them normally? Oct 29, 2014 at 13:29
  • @Fischer Yes, but i will do this automatically in lyx

    LyX exports and compiles LaTeX files in a temporary directory that your manually added code is not aware of. You should definitely let LyX do this. Check if there's a mention of image.pdf in Document>LaTeX log. Maybe LyX can't find epstopdf converter and falls back to eps to png conversion. Show us the LaTeX code (View>Source) when you insert the figure by Insert>Graphics. Check for all oocurences of image(.something) in the log. May 13, 2016 at 5:09

1 Answer 1


In my case, I had the same problem and nothing worked until I changed my directory to a non-UNC one. The UNC paths are not seemed to be supported by the epstopdf package (in my experience).

  • Now it looks better actually, thanks @azetina :)
