2010-05-24; LaTeX error parsing fails due to closing brackets in pdflatex output

[David Engster]

When I try to jump to an error in my LaTeX-file with TeX-next-error, I
get the message "Error occured after last TeX file closed". I'm using a
CVS checkout from today and the following pdflatex from Ubuntu 10.04:

----------------- snip -------------------------------

The reason for this seems to bet that there is a closing bracket without
a corresponding opening bracket in my pdflatex log output, which Auctex
interprets as the end of my LaTeX-File.

The line with the closing bracket looks like this:

--------------- snip --------------

[] [] \OT1/cmr/m/n/12 = [] \OML/cmm/m/it/12 ^^U[] \OT1/cmr/m/n/12 = []   \OMS/cmsy/m/n/12 ) [] [] \OT1/cmr/m/n/12 = []

--------------- snip --------------


If I delete this line from the log output before calling TeX-next-error,
Auctex jumps to the error as expected.

I can send you the complete output of the log via private mail if
necessary.

Regards,
David

The above line seems to be part of a formula from my tex file, which is
output after an "overfull hbox" warning.

I was able to circumvent this problem by using pdflatex's '-file-line-error'
option. I only stumbled upon that by browsing through the News section,
where this is noted for version 11.83, but it doesn't really say
how to activate this. I simply added it to `LaTeX-command-style', but
maybe there's a nicer/easier way?

Regards,
David

Yes, this should likely be added to the FAQ.

AFAIK you can also enable it globally in the configuration of your TeX
system.

Ah, yes. After some digging, I found 'file_line_error_style' in
/etc/texmf/texmf.d/95NonPath.cnf. Setting this to 't' and then calling
update-texmf did the trick (this is for the tex-common package on
Ubuntu/Debian).

Thanks,
David
