(I haven't find any answer in previous topics)

I am using Smart Tab globally, i.e. I have put the following code in my .emacs :

(require 'smart-tab)
(global-smart-tab-mode 1)

I am writing a program in Fortran, and I often need to indent some lines, which, according to smart-tab documentation, is done either by prefixing the smart-tab command (i.e. <tab>) by C-u or by selecting the region to be indented before hitting <tab>.

After some research, I still don't understand why only the "selecting a region" method works for me : to indent just one line, I need to have it selected, but C-u <tab> does not work, and always gives to following message (which I don't understand) :

Symbol's function definition is void: cl-case

Being able to indent any line (and just one line) by using <tab> in a simple command would solve my problem (while keeping smart-tab).

    Have you tried adding (require 'cl) to your config? That should help with this, but you shouldn't have any problem with this. Is your version of Emacs up to date?

As said in the comments on my question, adding (require 'cl) to my config file solved my problem (following DoMiNeLa10's suggestion).

N.B.: I am using Emacs 24.3.1.
