I removed my .emacs and .emacs.d, then created a new .emacs consisting of only the essential to use R and a shell with org-babel to make sure my configs weren't causing this:
(require 'org-install) (org-babel-do-load-languages 'org-babel-load-languages '( (sh . t) (R . t) )) When I try to run the following snippet:
#+begin_src R :results output verbatim (any R code) #+end_src It runs just fine. However, if I add :session or :session name to the #+begin_src header, Emacs freezes. I can't move the cursor nor do anything. I can see both R and Emacs on htop, none using any CPU. The only way to get out is to send SIGTERM to Emacs.
When running the snippet with C-c the minibuffer says:
ESS (*R*, R (newest)) starting data directory? pwd (I say yes) Cannot read history file pwd/.Rhistory This is normal, I get it on other computers where Emacs doesn't freeze. Then hangs forever on
ess-tracebug mode enabled Also normal. Except the hanging forever part.
A similar issue occurs with sh snippets:
#+begin_src sh :results output verbatim echo #+end_src Works fine. So with :session. However, with :session name it hangs forever just like R. All the minibuffer says is
Wrote /tmp/babel-XXXXX And then hangs forever on
executing sh code block... All packages (emacs, ess, org-mode) are the latest version from Debian stable repos. I have other computers with the same setup that work just fine. emacs --version returns GNU Emacs 24.4.1. The same happened in previous versions, and I also tried downloading Emacs 24.5.1 from a GNU mirror and compiling it. The exact same thing happens. I'm completely lost as to what could be causing this.
P.S.:
Also tried downloading latest stable ess and org-mode from the respective websites and installing and configuring for the compiled emacs. Added
(add-to-list 'load-path "/path/to/emacs-24.5/b/share/emacs/site-lisp/ess") (load "ess-site") To .emacs as per ess' README
