I have several org documents containing source code listings, with references such as the following:
```
* Section
#+name: codeblock
#+caption: Hello, world.
#+BEGIN_SRC C
// Hello, world
#+END_SRC
Reference to [[codeblock]].
```
I've been doing this for years, never had any problem.
Today, I get the following sort of LaTeX export (assuming the Listings package):
```
\section{Section}
\label{sec:orgheadline1}
\lstset{language=C,label=codeblock,caption={Hello, world.},captionpos=b,numbers=none}
\begin{lstlisting}
// Hello, world
\end{lstlisting}
Reference to \ref{orgsrcblock1}.
```
Well, there is no label orgsrcblock1, so the exported document shows "??" instead of a listing number.
I checked the manual to see if any of the syntax had changed, but I don't see any. I also tried doing
#+CAPTION:
#+NAME:
#+BEGIN_SRC
...
... but no difference -- I still get the wrong reference in the text.
So, how do I make source block references work the way they used to? Rather critical for me -- this is one of /the/ main reasons why I prefer to write in org and export LaTeX.
org 8.3.3 -- I'm using the packages provided by Ubuntu 16.04. (I realize distro packages are usually behind, but I wouldn't have expected a seriously broken org version to make it into package repositories, especially for a feature whose malfunction would not be tolerated by the technical writers in org's user base. So I suspect there must be some configuration issue, rather than a bug.)

Check org-latex-prefer-user-labels.

FWIW, I cannot reproduce it on a recent Org.

You could update Org.

I'm also surprised this doesn't work in Org 8.3.3, but my time machine
is being repaired at the moment, so there is nothing I can do about it.
Meanwhile, let me quote the usual licensing stuff, included in every Org
library (caps are not mine):
;; GNU Emacs is distributed in the hope that it will be useful,
;; but WITHOUT ANY WARRANTY; without even the implied warranty of
;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
;; GNU General Public License for more details.
Again, I suggest to update Org. Release 8.3.3 is very old.

OK, this works for me, thanks.
FWIW, org-latex-prefer-user-labels eluded me in the documentation. Now that you pointed me to it, I see the reason for the change, but I wouldn't have guessed it on my own.
I'll update org when I can.
In any case, thanks.
