Usage of deprecated font command `\rm'! (KOMA-script)

Question

I am using the scrreprt documentclass and I keep getting the warning:

Usage of deprecated font command `\rm'!(scrreprt) You should note, that in 1994 font command `\rm' has(scrreprt) been defined for compatiblitiy to Script 2.0 only.

Using a MWE, it comes out that the warning is generated from the commands \tableofcontents{} , \listoftables{} and \listoffigures{}

While digging a little bit further, my scrreprt.cls already contains \scr@DeclareOldFontCommand{\rm}{\normalfont\rmfamily}{\mathrm}

Does any one knows how to get rid of this warning?

Update: Here is a the MWE: Remark: I just found out that using the package fncychap is causing the warning. I use it to generate decoration rectangles at the beginning of chapters:

% !TeX spellcheck = en_US
\documentclass[11pt,headings=small,fleqn]{scrreprt} % highest level is chapter

\usepackage[Glenn]{fncychap} %To add a rectangle at the beginning of each chapter
\usepackage[greek,english]{babel} % for English text only

\begin{document}

\pagenumbering{roman} \setcounter{page}{1}

%%-----------Table of Contents------------------
\renewcommand{\contentsname}{Table of Contents}
\tableofcontents{}
\addcontentsline{toc}{section}{Table of Contents}
%%------------List of Tables----------------------
\listoftables{}
\addcontentsline{toc}{section}{List of Tables}
%%------------List of Figures----------------------
\listoffigures{}
\addcontentsline{toc}{section}{List of Figures}

%maintain Roman numerals on the previous page
\clearpage%set pagination to Arabic
\pagenumbering{arabic} 

\chapter{Chapter1}

\end{document}

Answer 1

The warning is caused by fncychap, which must use \rm for the Glenn style. I would just not use that package. If you really want it, add

\ChTitleVar{\bfseries\Large\rmfamily}
\ChNameVar{\bfseries\Large\sffamily}

after loading fncychap. These are copied from the fncychap manual, but with \rm replaced by \rmfamily and \sf replaced with \sffamily.

Additional notes:

• fontsize=11pt is the default for KOMA classes, so you don't actually have to specify it.

• With the scrbook class you get the \frontmatter, \mainmatter and \backmatter commands. The first sets up roman numbering of pages, the second switches to arabic.

• To add the float lists to the ToC, add listof=totoc as an option to the document class. This does not add the ToC itself to the ToC, but \setuptoc{toc}{totoc} will do that.

• By the way, \tableofcontents and \listof.. doesn't take an argument, so the brace pairs are unnecessary.

• As I switched from scrreprt to scrbook in the code below, I added oneside and openany to the class options, as that is what scrreprt does by default. Naturally, if you want margins set up for twosided printing and chapters to start on recto pages, remove those.

% !TeX spellcheck = en_US
\documentclass[
  headings=small,
  fleqn,
  oneside,
  openany,
  listof=totoc,
  toc=listof]{scrbook} % highest level is chapter

\setuptoc{toc}{totoc}

\usepackage[Glenn]{fncychap} %To add a rectangle at the beginning of each chapter
\ChTitleVar{\bfseries\Large\rmfamily}
\ChNameVar{\bfseries\Large\sffamily}
\usepackage[english]{babel} % for English text only

\begin{document}

\frontmatter

%%-----------Table of Contents------------------
\renewcommand{\contentsname}{Table of Contents}
\tableofcontents
%%------------List of Tables----------------------
\listoftables
%%------------List of Figures----------------------
\listoffigures

\mainmatter

\chapter{Chapter1}
