[Tex/LaTex] minted package: Undefined control sequence

minted

I just installed the minted package to type prettier code in my university reports, I'm trying it out but I keep getting the same messages when compiling:

This is the source:

\documentclass{report}
\usepackage{minted}
\begin{document}
\begin{minted}{c}
  int i,j,k,n;
\end{minted}
\end{document}

I compile it with:

pdflatex --shell-escape source.tex

This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian)

The output looks as expected but why does all of these messages appear?

Best Answer

Command \pdf@shellescape is defined in package pdftexcmds (part of bundle oberdiek), if the TeX compiler supports the status query of the write18/shell escape feature.

Therefore just add \usepackage{pdftexcmds} before \usepackage{minted}.
