[Bug-AUCTeX] 2011-05-15; TeX-source-correlate-method synctex instead of source-specials

[Rares Vernica]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report.  In addition check if the bug is reproducable with an
up-to-date version of AUCTeX.  So please upgrade to the version
available from http://www.gnu.org/software/auctex/ if your
installation is older than the one available from the web site.

If the bug is triggered by a specific (La)TeX file, you should try
to produce a minimal sample file showing the problem and include it
in your report.

Your bug report will be posted to the AUCTeX bug reporting list.

  I have checked out and compiled the latest auctex from CVS. I started
  emacs with "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.

  Thanks!
