Hi again, I succeed in exporting to .tex files with article.cls and book.cls but I do not succeed to export other classes. I do not even suceed in exporting in beamer class. I have in my emacs: (unless (boundp 'org-export-latex-classes) (setq org-export-latex-classes nil)) (add-to-list 'org-export-latex-classes '("beamer" "\\documentclass[11pt]{beamer}\n\\usepackage[utf8]{inputenc}\n\\usepackage[T1]{fontenc}\n\\usepackage{hyperref}\n\\usepackage{verbatim}\n" ("\\section{%s}" . "\\section*{%s}") ("\\begin{frame}\\frametitle{%s}" "\\end{frame}" "\\begin{frame}\\frametitle{%s}" "\\end{frame}"))) But it does not work : user-error: Unknown LaTeX class `beamer' I need again some help...
