# Showing labels for equations with eqnarray

I am using \usepackage{showlabels} to show the labels in the pdf-file but it turns out that I only see the labels coming from align or equation environment and not the ones from eqnarray. Why?

I personally don't like how align shows the formulas that's why I use eqnarray. Could I still show the labels for eqnarray equation?

Welcome to TeX.sx! eqnarray shouldn't be used for serious math typesetting, see tex.stackexchange.com/questions/196/eqnarray-vs-align –  egreg Mar 2 '13 at 13:31
Out of interest, what don't you like about the output from align? –  Ian Thompson Mar 2 '13 at 15:09

It should just work. Please always post complete documents that show the problem:

\documentclass{article}
\usepackage{showlabels}

\begin{document}

\begin{eqnarray}
1&=&2\label{aa}\\
33&=&44\label{bb}
\end{eqnarray}

$$P=NP\label{cc}$$

\end{document}
