Hello,
I tried to use calc with babel but it doesn't work as expected.
I use the following block with simple instruction :
#+begin_src calc
2*3
#+end_src
I didn't get back any results.
I launch calc and it seems to be called as I have following output
--- Emacs Calculator Mode ---
1: 6
.
So the instructions seems to be sent to calc.
I have the following message error message :
executing Calc code block...
calc-push-list: Symbol's value as variable is void: calc-command-flags
I use :
GNU Emacs 22.3.1 (i386-mingw-nt5.1.2600) of 2008-09-06 on SOFT-MJASON
Org-mode version 7.4
Regards
d.tchin

Hi d.tchin,
This problem is caused because (as you point out) the calc-command-flags
variable is not defined. In my Emacs version calc-command-flags is
provided by (require 'calc) which is part of Babel's calc support, this
variable must be part of another package in your distribution.
As a work around you should find which calc package provides the
calc-command-flags variable and manually require that package, which
should resolve this problem. More generally it may be useful to upgrade
from Emacs 22 if that is an option.

Strange as I can load calc package in emacs. Indeed when I try to
get information on this variable with C-h v, there is nothing.
I have a look on calc.el and I have the following lines (1428):
(defvar calc-aborted-prefix nil)
(defvar calc-start-time nil)
(defvar calc-command-flags)
(defvar calc-final-point-line)
(defvar calc-final-point-column)
Indeed, when I tried to use C-h v on the two first variable, it match.
But not for the following. The main difference is that the first two
variable have the nil value and not the following.

I put a (require 'calc) in my .emacs. It is still not working.
I decide to put the following instruction in my .emacs :
(require 'calc)
(defvar calc-command-flags nil)
Then it works !
It seems that there is problem of initialization of this variable.
Shouldn't this variable be initialized by default in calc ?
Thank you for your help.

the use of defvar without giving the variable a value is a trick to
appease the elisp compiler when a variable is used without being
required. I imagine that the `calc-command-flags' variable is defined
in some other calc file, which the calc authors assumed would already be
loaded by the time calc is required.

That may be the simplest work-around for now, unless you can find the
calc file that actually does define that variable.
