Ref: \ref{test}.
Cref: \cref{test}.



This produces Ref: 1. Cref: ?? 1.. I expected something like Ref: 1. Cref: Listing 1.

I get a LaTeX Warning: \Cref reference format for label type 'lstlisting' undefined on input line 9.

1 Answer 1


Solution 1

Add the following to your header:


Solution 2

Download the newest version from here (cleveref.dtx and cleveref.ins) and run latex cleveref.ins.

  • As I mentioned in the comments, your original MWE works fine if you just run it twice. Mar 12, 2012 at 4:09
  • It didn't, even after running it 10 times, because of the LaTeX Warning: \Cref reference format for label type 'lstlisting' undefined on input line 9.. Seriously, my cleveref version was to old :).

  • The link shows version 0.19 2013-12-28. tlmgr info cleveref tells I run 0.19 2014-02-26 which I assume is even newer. Still, I ran latex several times, and it would not detect the listing as a listing. Had to go with solution 1 :(

    @Dennis Just a small hint: The call to \Crefname is superfluous in the above case. As mentioned in section 8.1.2 of the cleveref documentation, "If the corresponding \Crefname is undefined when \crefname is called, it will automatically define \Crefname to be a capitalised version of \crefname, using \MakeUppercase."

    For those who run into the same issue having installed the current version as @mcnesium: Make sure that listings is included BEFORE cleveref!
