Thanks to Eric, Bastien and Thomas for their help.  I've switched from
listings to minted as I wasn't particularly wed to either and have
successfully implemented Thomas' suggestions.  

Apologies for the delay in responding: I've been in the mountains with
no connection to the world: bliss!

Aloha Giles,

A caption-aware LaTeX environment is provided by the minted package.
If you use org-special-blocks, then you can wrap your source block in
#+BEGIN_listing ... #+END_listing.  You can get a caption and label by
also including something like this within the special block:

#+LATEX: \caption{The caption.}\label{fig:src_blk}

If you want to stick with the listings package, then you will need to
define a listing environment that mimics what the minted package does.
There are at least two ways to do this in LaTeX (and probably others).
One way is to use the float package and then do something like this:

{\newfloat{listing}{h}{lol}
\newcommand\listingscaption{Listing}
\floatname{listing}{\listingscaption}
\newcommand\listoflistingscaption{List of Listings}
\providecommand\listoflistings{\listof{listing}{\listoflistingscaption}}
\floatplacement{listing}{htb!}

hth,
Tom

Currently code blocks are not wrapped in begin/end{figure} environments
as are links and tables.  I do not know of an easy way to do this aside
from manually inserting the LaTeX using #+LaTeX: lines in the Org-mode
file.  I personally would like to treat code blocks in the same way as
links and tables, but I'm not sure if there is a specific reason we do
not do this currently.

Thanks -- Eric

Since captions make sense for figures, I think you have to wrap this
in \begin{figure}\caption{}.  But maybe there is a way to automatically
wrap source blocks into a caption-aware LaTeX environment -- Eric might
give a more useful answer.

[O] src blocks, listings package and captions

[Giles Chamberlin]

I'm using the listings package and org-version 7.4 to generate latex/pdf
output including source snippets.  I'd like to add captions: "Figure 1:
My code" and tried with the following to no avail:

#+caption: My code
#+begin_src clojure
 ;; stuff
#+end_src

Do I have to wrap this in \begin{figure}\caption{} or is there a simpler
way?
