Package pdftex.def Error: File `./essai-eps-converted-to.pdf' not found

Question

I read all the previous questions on the automatic epstopdf conversion which does not work and none answers my own problem though I am in a seemingly identical case with some of the previously reported cases.

I use TexStudio 2.8.6 on a Mac 10.7.5. I have made a simple test case document.tex trying to load an essai.eps file in it. It does not work :

Package epstopdf Info: Source file: <essai.eps>
(epstopdf)                    date: 2014-12-04 13:00:47
(epstopdf)                    size: 48317 bytes
(epstopdf)             Output file: <./essai-eps-converted-to.pdf>
(epstopdf)             Command: <epstopdf --outfile=./essai-eps-converted-to.pd
f essai.eps>
(epstopdf)             \includegraphics on input line 154.
runsystem(epstopdf --outfile=./essai-eps-converted-to.pdf essai.eps)...executed
.

Package epstopdf Info: Result file: <./essai-eps-converted-to.pdf>.

! Package pdftex.def Error: File `./essai-eps-converted-to.pdf' not found.

See the pdftex.def package documentation for explanation.

I have tried to add -shell-escape or --shell-escape (is it 1 or 2 dashes? both are mentioned in the different posts), i also added usepackage[outdir=./]{epstopdf}. Nothing works. However the problem is internal to TexStudio since running pdflatex document.tex on the command line works perfectly and produces the .pdf images I need.

Therefore I guess that TexStudio is trying to write the file in a strange place and possibly in a place where it is not authorized to write because a global search on the whole hard drive does not find the file.

What is wrong with TexStudio ?

Answer 1

The .log shows:

runsystem(epstopdf --outfile=./essai-eps-converted-to.pdf essai.eps)...executed

But the file does not seem to be generated, thus the conversion failed. Try to do it manually, the command is given above. Option --debug gives more hints, what might went wrong:

epstopdf --debug --outfile=./essai-eps-converted-to.pdf essai.eps

The Perl script epstopdf calls ghostscript for the actual conversion from EPS to PDF. A further calls it directly:

ps2pdf -dEPSCrop essai.eps
