I recently upgraded to the latest git version and every asynchronous export to pdf in beamer mode fails whereas the asynchronous mode has no problem. I didn't change anything in my setup, and it was working fine before.
With the following Org file (the first lines are to ensure that the latest git version of Org is used) --8<---------------cut here---------------start------------->8--- #+BEGIN_SRC emacs-lisp :exports none :results none (add-to-list 'load-path (expand-file-name "~/info/emacs/org-mode/lisp")) (add-to-list 'load-path (expand-file-name "~/info/emacs/org-mode/contrib/lisp")) (setq org-export-async-init-file "/home/wilk/configuration/elisp/org-export-async-init.el") (org-reload) (setq org-export-async-debug t) #+END_SRC * Test essai --8<---------------cut here---------------end--------------->8--- Calling (in emacs -Q) an asynchronous export to Tex for Beamer (C-c C-e l b) gives the following error --8<---------------cut here---------------start------------->8--- Unknown "nil" back-end: Aborting export --8<---------------cut here---------------end--------------->8--- There is no error for an export to TeX in LateX mode (C-c C-e l l), of if the export to TeX in beamer mode isn't asynchronous. The contents of the "/home/wilk/configuration/elisp/org-export-async-init-test.el" file are: --8<---------------cut here---------------start------------->8--- ;;~/.emacs -*- mode: lisp-*- (setq org-export-async-debug t) (add-to-list 'load-path (expand-file-name "~/info/emacs/org-mode/lisp")) (add-to-list 'load-path (expand-file-name "~/info/emacs/org-mode/contrib/lisp")) (require 'org) (require 'ox) --8<---------------cut here---------------end--------------->8--- Any idea what went wrong ?
