Subject: bug#8698: 24.0.50; TeX-source-correlate-method synctex instead of source-specials

From: Rares Vernica <[email-masked]>
Date: Wed, 18 May 2011 20:57:42 -0700

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the [email-masked] mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

  I loaded tex-site.el and wrote a short .tex file:

    \documentclass{article}
    \begin{document}
    a
    \end{document}

  After that I enabled TeX-source-correlate-mode:

    M-x TeX-source-correlate-mode

  I compiled the .tex file. The compile command was:

    latex --synctex=1 -interaction=nonstopmode "\input" a.tex

  Notice the use of --synctex=1. After compilation, the View command was:

    xdvi -sourceposition "4 a.tex" -editor
    "/home/rares/usr/bin/emacsclient --no-wait +%l %f" a.dvi

  Notice -sourceposition. Xdvi gives the following waring:

    No source specials in this DVI file - couldn't do reverse search.

  So, Xdvi needs source-specials, but the file is compiled with
  synctex. I checked the TeX-source-correlate-method variable and it
  says:

    TeX-source-correlate-method is a variable defined in `tex.el'.
    Its value is auto

    Documentation:
    Method to use for enabling forward and inverse search.
    This can be `source-specials' if source specials should be used,
    `synctex' if SyncTeX should be used, or`auto' if AUCTeX should
    decide.
  
  A workaround is to do:

    (setq TeX-source-correlate-method 'source-specials)

  before TeX-source-correlate-mode is enabled.

  I am using auctex 11.86-2ubuntu1.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
