I've been setting up emacs and xpdf for use with lilypond 17.25 on
Ubuntu 13.04, using emacs 24.3, and the Debian install files for xpdf
3.03 and libpoppler19. Most things seem to be working - I have syntax
highlighting, I can run Lilypond with C-c C-l, and C-c C-s opens the
PDF output in xpdf. But when I click on a hyperlink in the PDF output,
what happens is that a new emacs window opens with another copy of
the ly source file and the cursor is positioned there. If I click on
another hyperlink, yet another emacs window with yet another copy of
the source opens...and so on.
What do I need to configure to get the hyperlink to go to the ly
source file that I already have open in emacs? I followed the
instructions at
http://www.lilypond.org/doc/v2.17/Documentation/usage/configuring-the-system-for-point-and-click
to do the configuration for emacs and xpdf.
