Re: [O] Orgmode Latex Export with Babel/LilyPond

[adam]

Still no success in tangling the examples  modal-cycle.org  modal-cycle2.org  
shown here, 
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-lilypond.html 

My current problem is Emacs rejecting the addition of either Lilypond or 
lilypond, in the  org-babel-do-load-languages  

   (org-babel-do-load-languages
     'org-babel-load-languages
     '(
       (emacs-lisp . t)
       (shell . t)
       (org . t)
       (Lilypond . t)
       )) 

including either in the last line causes an error at Emacs startup, reported 
as, 

   Warning (initialization): An error occurred while loading 
‘/home/user/.emacs’:
   Symbol's value as variable is void: <!DOCTYPE


Earlier in my .emacs init file, I had hopefully defined lilypond, thus 

   (setq ly-nix-ly-path "lilypond")

   (add-to-list 'load-path "/usr/share/emacs/site-lisp/") 

   (autoload 'LilyPond-mode "lilypond-mode")

   (setq auto-mode-alist
         (cons '("\\.ly$" . LilyPond-mode) auto-mode-alist))

   (add-hook 'LilyPond-mode-hook (lambda () (turn-on-font-lock))) 


In  /usr/share/emacs/site-lisp/   many lilypond related .el files 
are located,

   lilypond-font-lock.el
   lilypond-indent.el
   lilypond-init.el
   lilypond-mode.el
   lilypond-song.el
   lilypond-what-beat.el
   lilypond-words.el
   ltx-help.el
   ob-lilypond.el
   ob-Lilypond.el
   ob-lisp.el
   org-tests.el


$ which lilypond     is unhelpful,

   /usr/bin/lilypond 


The lilypond installation is at, 

   /usr/share/lilypond/2.18.2/ 


Any advice or suggestions would be most welcome.
