[Tex/LaTex] Undefined control sequence with hypersetup in moderncv

hyperrefmoderncv

The MWE below results in the error:

Undefined control sequence. \hypersetup

It's minimized from a CV that definitely compiled fine a month ago (with the warnings discussed in What does "You have requested package `foo', but the package provides `foo'." mean?). I've tried in up-to-date setups of both MiKTeX and TeX Live. I suspect some package that was updated in the meantime is causing an incompatibility, but having a hard time tracking down which one. I'm hoping someone can identify it, so that I can revert to an older version, or suggest a workaround.

\documentclass{moderncv}

\moderncvstyle{banking}
\moderncvcolor{black}
\name{John}{Doe}

\hypersetup{}

\begin{document}

\makecvtitle

Lorem ipsum

\end{document}

Changing the documentclass to article (and replacing the moderncv specific lines with \usepackage{hyperref}) makes it compile fine. If I include

\usepackage{hyperref}

I get an Option clash for package hyperref. error, presumably because moderncv is loading hyperref.

Best Answer

There is an easy workaround: simply move comand \hypersetup behind \begin{document} like this:

\documentclass{moderncv}

\moderncvstyle{banking}
\moderncvcolor{black}
\name{John}{Doe}

%\hypersetup{} % <========================================= move it down

\begin{document}
\hypersetup{} % <=======================================================

\makecvtitle

Lorem ipsum

\end{document}

The reason is that class moderncv, current version 2.0, loads hyperref with AtEndPreamble. That means that hyperref is called after your complete preamble. That means that your call is to early, at that moment hyperref is not loaded and therefore \hypersetup is an unknown command, resulting the error message you got.

With the moved command \hypersetup after \begin{document} package hyperref is already called and \hypersetup is a valid command ...
