simple.tex does not require examheader. Can you provide a source file we can compile to test the barcode?

Sorry.
The simple.tex that I uploaded does require examheader. I probably should have renamed it.

It seems OK using latex, dvips and then ps2pdf.

Right. When I run
pdflatex --shell-escape simple.tex
it works correctly. However, when I hit the "Update Documents" button in the gui, I get the error message that I mentioned above.

In the preferences, my latex engine is listed as
pdflatex --shell-escape,
so I would assume that it should compile correctly. But, it does not.

Again,
this is an error I see in the AMC app, not when I compile directly. I apologize that that wasn't evident in my first post.

Thanks,
S.M.

pdflatex --shell-escape simple.tex does not work with me: I have

Package pst-pdf Warning: `simple-pics.pdf' contains 1 pages 
(pst-pdf)                but 10 pages are requested: 
(pst-pdf)                File `simple-pics.pdf' is no more valid! 
(pst-pdf)                Recreate it .

Interesting. It works for me. auto-pst-pdf is supposed to do the intermediate steps. I don't want to bother you with this anymore, since different people are getting different behaviors. Like I said, I can create it outside of AMC, and include it as a graphic. So, I'm not sure this is worth bothering about. If I get more time, I'll try to figure out what is going on.

Thanks,
S.M.

Hi, i'm experiencing he same issue generating the PDF file inside AMC, when I run "pdflatex --shell-escape simple.tex" from terminal it works.
It works also changing the dafault Latex Engine to "latex+dvipdf" inside AMC but it's very slow generating the output file(s).
I'm new to LaTex, the issue is generated trying to write a BarCode in the document, the OS is Ubuntu 14.04 desktop.
Thanks in advance for your support.

Here is part of the log inside AMC:

-------------------------------------------------
auto-pst-pdf: Auxiliary LaTeX compilation

Yes, this is what I get. Works great outside of AMC, doesn't work at all inside AMC. I haven't had time to do some code diving to see what is going on. I suspect that it has to do with the fact that amc tricks latex into thinking the filename is different, and somehow that is messing auto-pst-pdf up.
