i am using Auctex under emacs 24.3.1 on mac. I am making master .tex file and many what i call it child .tex files. Run Latex and Run bibtex commands are working nicely from either the master file or from child files but i can not view the output except from the master file. I would appreciate very much your answer(s). Thanks in advance. Ayman

    Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. Did you set TeX-master appropriately in the child file? (I would set it as a file-local variable.) Mar 9, 2014 at 20:18

Add the following at the very end of each of your 'child' files:

% Local Variables:
% TeX-master: "./my-master-file.tex"
% End:

If you already have a Local Variables block, just add the appropriate line.

Close and re-open your file; this should set the variable. (You can also call M-x normal-mode if you don't want to close the file.)

    To reload a file there is M-x revert-buffer and I would add the suggestion to insert (setq TeX-auto-save t) (setq TeX-parse-self t) (setq-default TeX-master nil) in the .emacs file.

I believe i found out what the problem was. It is the configuration of skim and latexmk in the .emacs file. the perfect setting that is really works is as following

;; Skim's displayline is used for forward search (from .tex to .pdf)
;; option -b highlights the current line
;; option -g opens Skim in the background
;; option -o open Skim in the foreground with full application focus.

'(LaTeX-command "latex -synctex=1")
(require 'tex-site)
(add-hook 'TeX-mode-hook
    (lambda ()
        (add-to-list 'TeX-output-view-style
            '("^pdf$" "."
              "/Applications/Skim.app/Contents/SharedSupport/displayline -b %n %o %b")))

(setq TeX-PDF-mode t)

(setq TeX-source-correlate-mode t)

(setq TeX-source-correlate-method 'synctex)
(add-hook 'LaTeX-mode-hook 'TeX-source-correlate-mode)

;; make latexmk available via C-c C-c
;; Note: SyncTeX is setup via ~/.latexmkrc (see below)
(add-hook 'LaTeX-mode-hook (lambda ()
    '("latexmk" "latexmk -pdf %s" TeX-run-TeX nil t
      :help "Run latexmk on file")
(add-hook 'TeX-mode-hook '(lambda () (setq TeX-command-default "latexmk")))

;; use Skim as default pdf viewer
;; Skim's displayline is used for forward search (from .tex to .pdf)
;; option -b highlights the current line; option -g opens Skim in the background  
(setq TeX-view-program-selection '((output-pdf "PDF Viewer")))
(setq TeX-view-program-list
     '(("PDF Viewer" "/Applications/Skim.app/Contents/SharedSupport/displayline -b -g %n %o %b")))

(server-start); start emacs in server mode so that skim can talk to it

(add-hook 'LaTeX-mode-hook
          (lambda () (local-set-key (kbd "<S-s-mouse-1>") #'TeX-view))

and of course, in the skim you have to do Preferences>Sync>Check for file changes and Preset>Emacs
