LaTeX/Emacs problem

LaTeX/Emacs problem

[Fred Krogh]

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.

You might also like to check the texmf.cnf file. Could be that TeX is set up incorrectly. Look for file_line_error_style! And better correct the value in it's local copy, containing only the local changes from the defaults. (Because otherwise your change might be removed by a TeX update.)

Thanks, this looked like a really good suggestion.  So I found 
/etc/texmf/web2c/texmf.cnf and I had no /etc/texmf.cnf.  Following 
instructions I created the file /etc/texmf.cnf and put the following 
into it.

% Control file:line:error style messages.
file_line_error_style = t

since the /etc/texmf/web2c/texmf.cnf had that line with f where I put a 
t at the end of the line.  I expected this to work, but it behaves the 
same way.  This being gentoo, I looked for the package this file belongs 
to, "equery b /etc/texmf/web2c/texmf.cnf", and no package seems to own 
the file.  (I was going to reinstall whatever package claimed the file.) 
  On a (second) guess I reinstalled auctex, and that changed the time 
stamp on the file even though that file is not listed as belonging to 
auctex??

So I am very open to further suggestions.

Have you tried to update all formats after the change in texmf.cnf? Maybe this is the final necessary step…

I'm not sure what is suggested here.  I found /usr/sbin/texmf-update and 
ran it, but that fixed nothing.   I tried rehash and format running 
texconfig.  The former didn't help, and the latter said it was no longer 
supported.  Thanks for trying.  Am I missing what was suggested?

Re: LaTeX/Emacs problem

[Fred Krogh]

Another note.  As a result of scanning for something else, I tried this:
fc-cache  -rf&& mkfontscale && mkfontdir
That too had no effect.

Re: LaTeX/Emacs problem

[Fred Krogh]

Sorry I keep coming across things to try.  I hope this is the last one.
fmtutil-sys --all

I suspect this is what was suggested in the first place.  I'm giving up 
for now.

Re: LaTeX/Emacs problem

[Pierre Lorenzon]

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.

Regards

Pierre

"sudo fmtutil-sys --refresh" is the command I was thinking of…

The command fmtutil-sys is to be used with super-user privileges (for private use the command fmtutil exists). Its option "--all" will only then lead to actions when some file that is "included" by a FMT is newer than the FMT file. This means that *not* all FMT files will be updated. Texmf.cnf is not considered  as such a file.

If this leads to the same failures as before, you might consider launching GNU Emacs with -Q, i.e. without customisation. Then load AUCTeX manually – from the *scratch* buffer with its Emacs Lisp interpreter – and then load a faulty (La)TeX file and compile it. If in this case all works as it should, then something in your customisation could be faulty.

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.

You can use \listfiles in the preamble, or as first line of the file, to create an exact list of all files that were used by LaTeX. The LOG file will also record which version of the latex binaries you are using. Then compare your output with that of root!

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.

Not using GNU Emacs I get in the console:

And this is the output from AUCTeX 11.86 from inside GNU Emacs 24.3.50:

Quite similar behaviour. (I do need to update my hyphenations configuration! I'll never use Friulan or Rumansh!) When I then choose from AUCTeX's Commands menu the item "Next Error" it shows me that error and open a buffer with that contents:

	ERROR: Undefined control sequence.
	
	--- TeX said ---
	l.4 \Nothing
	             to see here folks.
	--- HELP ---
	TeX encountered an unknown command name. You probably misspelled the
	name. If this message occurs when a LaTeX command is being processed,
	the command is probably in the wrong place---for example, the error
	can be produced by an \item command that's not inside a list-making
	environment. The error can also be caused by a missing \documentclass
	command.

When I then remove the comment sign, save, and run LaTeX again, I get the same error. When I then choose the same command, AUCTeX asks me for the master file. When I give the correct answer, it opens *TeX Help* buffer with the same contents – and buries the buffer with the TeX file with an empty "TeX Live 2012" buffer. This latter effect certainly is not needed.


When I open an empty TeX file under the control of AUCTeX, it asks me for the master file. I show it the master file by pressing the RETURN key. I insert your example and get as buffer and file contents:

	\documentclass{article}
	%\usepackage{hyperref}
	\begin{document}
	\Nothing to see here folks.
	\end{document}
	
	%%% Local Variables: 
	%%% TeX-master: t
	%%% End: 

With the commented line the behaviour is as before: OK. With the uncommented line, the behaviour is as before: not OK!

This is a bug in AUCTeX. It's even two bugs: why does it ask me for the master file? The opened file in the buffer is *obviously* the master. To report it, choose "Report Bug" from the Preview menu!

Similar behaviour in GNU Emacs 24.2 launched with -Q. I consider reporting mine tomorrow. I'll have to read the documentation to be sure that it's not me who is buggy.

  Not for auctex until the local variable TeX-master has not
  being correctly set. But auctex behavior can be customized at
  this point I think.
