I am using MikTeX and I have suddenly started to get a problem with amsmath. I have managed to reduce it to the following MWE:
\documentclass[a4paper,11pt]{article}
\usepackage{amsmath}
\begin{document}
Some text
\end{document}
When I compile, I get the message:
Unable to properly define \@@leqno. primitive \leqno no longer primitive\@saveprimitive\eqno\@@eqno
I have recently updated MikTeX and I am using amsmath v2.17o.
If I comment out the \usepackage{amsmath}
the file compiles without any error message.
<filename>.log
. Post at least the first 50 lines or so, so we can see what the various package versions are according to the latex compiler.
