Hello Nick, hello everybody, I have finally got the solution. I have put again in my init.el the code from the page http://orgmode.org/worg/org-tutorials/org-latex-preview.html , i.e. (setq org-latex-listings 'minted) (require 'ox-latex) (add-to-list 'org-latex-packages-alist '("" "minted")) and I have added this one foiunded on the web (I do not remind where exactly): ;; Let the exporter use the -shell-escape option to let latex ;; execute external programs. ;; This obviously and can be dangerous to activate! (setq org-latex-pdf-process '("xelatex -shell-escape -interaction nonstopmode -output-directory %o %f")) Now it works. But I do not know really why.
