Hi all, I am trying to debug an issue with installing org-mode from Melpa.
After installing org from Melpa, I get this on starting emacs: byte-code: Invalid function: org-babel-header-args-safe-fn Org-mode version 8.3.3 (8.3.3-51-g30bcff-elpaplus @ /Users/jkitchin/Desktop/jmax-git/elpa/org-plus-contrib-20160208/) It is happening when I try to change some default headers. Debugger entered--Lisp error: (invalid-function org-babel-header-args-safe-fn) org-babel-header-args-safe-fn((:cache :colnames :comments :exports :epilogue :hlines :noeval :noweb :noweb-ref :noweb-sep :padline :prologue :rownames :sep :session :tangle :wrap (:eval "never" "query") (:results lambda (str) (not (string-match "file" str))) :width :height :bg :units :pointsize :antialias :quality :compression :res :type :family :title :fonts :version :paper :encoding :pagecentre :colormodel :useDingbats :horizontal)) byte-code("\301\302\303\304!#\210\305\306\307\310\311\312\313\314\315\316& \207" [ob-R-safe-header-args put org-babel-default-header-args:R safe-local-variable org-babel-header-args-safe-fn custom-declare-variable org-babel-R-command "R --slave --no-save" "Name of command to use for executing R code." :group org-babel :version "24.1" :type string] 10) require(ob-R) #[(pair) "A\303@!\211\203 \304\305\306 P!!\202%\307\305\310 P!!\210\307\305\311 P!!*\207" [pair lang active symbol-name require intern "ob-" fmakunbound "org-babel-execute:" "org-babel-expand-body:"] 5]((R . t)) mapc(#[(pair) "A\303@!\211\203 \304\305\306 P!!\202%\307\305\310 P!!\210\307\305\311 P!!*\207" [pair lang active symbol-name require intern "ob-" fmakunbound "org-babel-execute:" "org-babel-expand-body:"] 5] ((emacs-lisp . t) (python . t) (sh . t) (matlab . t) (sqlite . t) (ruby . t) (perl . t) (org . t) (dot . t) (plantuml . t) (R . t))) org-babel-do-load-languages(org-babel-load-languages ((emacs-lisp . t) (python . t) (sh . t) (matlab . t) (sqlite . t) (ruby . t) (perl . t) (org . t) (dot . t) (plantuml . t) (R . t))) eval-buffer(#<buffer *load*> nil "/Users/jkitchin/Desktop/jmax-git/jmax-org.el" nil t) ; Reading at buffer position 7097 If I run this: (byte-recompile-file (expand-file-name "ob-R.el" (file-name-directory (locate-library "org"))) t) the problem goes away. I haven't been able to come up with a simple reproducible example. This happens when I start my jmax starter kit from scratch. It does not happen though if I strip that down to just installing org, then I do not see the issue. Any hints on tracking this down?
