Hi Rasmus,

Thank you very much for testing the patch!

Indeed, the jump from emacs -> pdf is not implemented.  I’ve got some
complicated dbus voodoo (attached to this email, in case it is useful
for you or others) in my init.el to get that working with AucTeX – I am
also using evince as the viewer).  So I will have to investigate how to
add that feature.

The jump from pdf viewer -> org should be working though, assuming it
does for you in auctex.  (I also have some dbus arcana for that portion
in my init.el file; I assume you do too).

Ideally, I think ox-synctex should eventually include the configurations
for as many pdf viewers as possible, so that users do not need to
configure this themselves.  (Ideally x 2, some external library would
already provide this...)

This is right; I added both just to be safe (and dired, which was also
needed since I borrow a defcustom from there).

One thing I forgot to mention in my last email is that you need to
customize your org-latex-pdf-process to make the latex compiler generate
a synctex file.  (This is a command line switch, but it differs across
(pdf/xe/lua)tex.)  So this could be why it does not work for you in
emacs -q.  The following bit of code suffices, after M-x load-library
ox-latex:

(setq org-latex-pdf-process 
      '("pdflatex -synctex=1 -interaction nonstopmode -output-directory %o %f"))

I attach another version of the patch, with the missing requires as well
as some more logging code.  If it doesn’t work for you, could you
perhaps send me the lines in *Messages* generated by the export?
