Hi,

I encountered similar problems but not everytime ! With certain
files errors cannot be detected and with other ones not. It
sometimes depent on the place LaTeX is started from i.e. from
the master file or not. In fact I have not completely
identified the circumstances for which error finding
fail. Anyway I suspect that your problem is an auctex problem
and that you'd try to post on the auctex mailing list. If you
might determine more precisely when error finding fails it
might maybey help to determine where this bad behavior comes
from.


This sounds like what I'm seeing now.

First of all, all the commands I've entered dealing with things like
fmtutil-sys were run as root.

I have one short file that worked when run as root, but not as my usual
user.  A longer tex file never works.

I uninstalled auctex, and things worked as one might expect without
auctex.  The program tended to run to completion with an error message.
(I was simply inserting a command like \xxx.)

I then reinstalled auctex, and the short tex file worked very nicely
with my usual user, and as root.  The long tex file (the kind I care
about) worked with neither.

More sleuthing, and the long tex file works if I comment out
\usepackage{hyperref}

So that is looking like the real culprit.  Heiko Oberdiek is the
maintainer of hyperref and if this email should reach him perhaps he
will have some ideas.  For his information I've added my original message.
=======
A long time ago when I ran latex from inside emacs, if there were errors
it would point me to the place with the error (maybe after <cntrl c
>?). For the last few years, when there was an error, I had to type
<cntrl c > that gave me a line number, I then had to kill that window
to get back to my latex buffer, go to that line and fix the problem. Now
another step backwards. After <cntrl c > all I get now is " Error
occurred after last TeX file closed". The only choice at this point
seems to be running latex in a separate terminal window. I'd be
interested if anyone else is having these sorts of problems, suggestions
for tracking down the problem, or if you have it working perhaps your
.emacs.el file?  I'm running TeXLive on a gentoo linux system.  Many
thanks.


I have had a little correspondence with Heiko Oberdiek (heiko.oberdiek@googlemail.com). He is not an emacs user, but has said "If you get an answer that suggests an improvement in hyperref, let me know." I guess if anything is going to happen with this issue, it is up to someone who understands emacs well enough to illustrate the problem without actually using emacs. He would be willing to take a look if the problem can be expressed in a way that does not involve emacs. Here is an example

\documentclass{article}
%\usepackage{hyperref}
\begin{document}
\Nothing to see here folks.
\end{document}


Run latex from inside emacs and this will flag the "\Nothing" and position the cursor on that line. Remove the % at the start of the second line, delete the *TeX Help buffer, do the same, and you will get "Error occured after last TeX file closed" and nothing else.
