For reference: I got it to work by adapting the snippet from Bruno Tavernier[1]: #+begin_src emacs-lisp (defun my-auto-tex-cmd (backend) "When exporting from .org with latex, automatically run latex, pdflatex, or xelatex as appropriate, using latexmk." (let ((texcmd)) (setq texcmd "latexmk -pdf %f") (if (string-match "LATEX_CMD: pdflatex" (buffer-string)) (setq texcmd "latexmk -pdflatex=pdflatex -pdf %f")) (if (string-match "LATEX_CMD: pdflatex-shell-escape" (buffer-string)) (setq texcmd "latexmk -pdflatex=pdflatex --shell-escape -pdf %f")) (if (string-match "LATEX_CMD: xelatex" (buffer-string)) (setq texcmd "latexmk -pdflatex=xelatex -pdf %f")) (setq org-latex-pdf-process (list texcmd)))) (add-hook 'org-export-before-parsing-hook 'my-auto-tex-cmd) #+end_src One thing that tripped me up initially was the requirement for the function to accept exactly one argument (unused in this case).
