On windows I have a problem when the source file is on a directory that is a shortcut.
This problem occurs with with MikTex (MiKTeX EPS-to-PDF Converter 2.9.7229 (MiKTeX 2.9.7250 64-bit)) as well as with Tex Live (Sorry I don't have the version information from epstopdf, but This is pdfTeX, Version 3.14159265-2.6-1.40.21 (TeX Live 2020/W32TeX)).
I have the directory
Path_original with a shortcut called
Path to this directory (for the tests they are both in the current directory). On the
Path_original dirctory there is the file
epstopdf "Path/an_eps.eps" "--outfile=Path/an_eps.pdf"
gives the error message (on the console):
Sorry, but epstopdf did not succeed. The log file hopefully contains the information to get MiKTeX going again: C:\Users\User\AppData\Local\MiKTeX\2.9\miktex\log\epstopdf.log
and in the log file:
2020-05-10 15:40:03,882+0200 INFO epstopdf - starting with command line: epstopdf Path/an_eps.eps --outfile=Path/an_eps.pdf 2020-05-10 15:40:03,882+0200 FATAL epstopdf - The input file does not exist. 2020-05-10 15:40:03,882+0200 FATAL epstopdf - The input file does not exist. 2020-05-10 15:40:03,882+0200 FATAL epstopdf - Info: 2020-05-10 15:40:03,882+0200 FATAL epstopdf - Source: 2020-05-10 15:40:03,882+0200 FATAL epstopdf - Line: 0
epstopdf "Path_original/an_eps.eps" "--outfile=Path_original/an_eps.pdf"
succeeds without problems
The way of addressing the directory is out of my control i.e. the user of the (doxygen) package decides where the files reside (it is however possible that I modify doxygen slightly to address this problem).
Is there a solution inside epstopdf or outside epstopdf for this problem?
