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

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.
