Making pdf-tools work after successful compiling on mac os x

Question

After installing the required dependencies with homebrew, I was able to compile pdf-tools . But I cannot make it work (I cannot see the pdf on emacs after compiling)

I would like to know if somebody can post its .emacs config to make pdf-tools work since I have not been able to make it happen. I have tried several options, like the following (copy from somebody else):

(load "pdf-tools") ;;
(setq output-pdf "PDF Tools") ;;          
(pdf-tools-install)                                                   
(setq TeX-view-program-selection '((output-dvi "Okular")              
                                   (output-pdf "PDF Tools") ;;        
                                   ))

Or also

;; Use pdf-tools to open PDF files
(setq TeX-view-program-selection '((output-pdf "PDF Tools"))
      TeX-source-correlate-start-server t)

;; Update PDF buffers after successful LaTeX runs
(add-hook 'TeX-after-TeX-LaTeX-command-finished-hook
           #'TeX-revert-document-buffer)

But, after compiling a tex file (with C-c C-c with Auctex) and trying to see the pdf with the same command (and selecting View), I always get the error

Unknown PDF Tools viewer. Check the Tex-view-program-selection variable

I am sure I am missing a key config for making pdf-tools available or known to auctex/emacs, but cannot figure it out. Could you please post your config to get an inspiration from it? I have already checked install-pdf-tools-on-emacs-macosx, how-to-let-auctex-open-pdf-with-pdf-tools and how-to-use-pdf-tools-pdf-view-mode-in-emacs without success.

Thanks in advance.

Edit: Making already visited links more explicit.

Answer 1

The problem is that you need to add "PDF Tools" to the list of available PDF Tools. This must happen automagically for some people (or there would be more complaints about this on stackexchange!), but apparently not for you or me.

Here is my config:

(pdf-tools-install) ;; start server
(load "pdf-tools") ;; not clear if this is needed.

;; add "PDF Tools" to the list of possible PDF tools
(unless (assoc "PDF Tools" TeX-view-program-list
  (add-to-list 'TeX-view-program-list
           '("PDF Tools" TeX-pdf-tools-sync-view)))
(add-to-list 'TeX-view-program-selection
          '(output-pdf "PDF Tools"))

(setq TeX-view-program-selection '((output-pdf "PDF Tools")))

;; Update PDF buffers after successful LaTeX runs
(add-hook 'TeX-after-TeX-LaTeX-command-finished-hook
         'TeX-revert-document-buffer)

Answer 2

Assuming your auctex is up-to-date and that you followed the instructions for installing the package, including the M-x package-install-file RET pdf-tools-${VERSION}.tar RET step, all you should need is

;; Initialize the package (this should autoload it too)
(pdf-tools-install)
;; Select PDF Tools as your viewer for PDF files
(setcdr (assq 'output-pdf TeX-view-program-selection) '("PDF Tools"))
;; If you want synctex support, this should be sufficient assuming 
;; you are using LaTeX-mode
(add-hook 'LaTeX-mode-hook 'TeX-source-correlate-mode)
