How to change default PDF viewer?

[Nikolaus Rath]

Hello,

Can someone tell me how to change the default PDF viewer from Emacs' new
internal document viewer to an external program?

Thanks,
-Nikolaus

on linux emacs reads the user .mailcap file.
you should define which program you want to use in it.

The mailcap file defines *external* viewers. My problem is that
Gnu/emacs is using its *internal* viewer, and *not* an external one.

I had the same issue. The problem these days is that Emacs favours a
Lisp based reader (doc-view, in this case) to whatever is define in
mailcap. I googled the problem and this is the solution I found that
works. For example, I have define Okular as the pdf reader in mailcap:

#+BEGIN_SRC emacs-lisp
;;Remove doc-view so pdf will open with Okular
(setcdr
(assoc "application" mailcap-mime-data)
(remove '("pdf"
(viewer . doc-view-mode)
(type . "application/pdf")
(test eq window-system 'x))
(cdr (assoc "application" mailcap-mime-data))))
#+END_SRC

Just cut and paste what is between BEGIN_SRC and END_SRC and put it in
your init file.

Works perfectly! Thanks a bunch!
