So entfernen Sie "fragilen" Text

Question

Ich verwende diesen Code, um einen Rahmen zu generieren, in dem mein Code eingefärbt ist, aber jedes Mal, wenn ich ihn verwende, erscheint dieses seltsame kleine „[fragile]“-Tag. Was mache ich falsch?

\documentclass{report}
\usepackage{graphicx,parskip,bibunits,appendix,float,todonotes,pstricks,subfigure}
\usepackage[ruled] {algorithm2e}
\usepackage{url,amsmath,amssymb,fancybox,listings,pdfpages,caption,multicol,datetime,rotating, booktabs}
\usepackage[pagebackref=false,pdffitwindow=true]{hyperref}
\usepackage[bottom]{footmisc}
\begin{document}
\begin{frame}[fragile]
\lstset{language=C++,
            basicstyle=\ttfamily,
            keywordstyle=\color{blue}\ttfamily,
            stringstyle=\color{red}\ttfamily,
            commentstyle=\color{gray}\ttfamily,
            morecomment=[l][\color{magenta}]{\#}
}
\begin{lstlisting}

for(int i = 0; i < 4; i++){
   for(int j = 0; j < 2; j++){
     glPushMatrix();
     // We move the chair and table to their new location
     glTranslatef(-250.F + 220.F * i - 70.F * j,
     .0F, 20.F + 150.F * j);

     // if it's on the second row, we slightly rotate it
     float angle = j==0?-60.F:15.F*i;
     glRotatef(angle, 0, 1, 0);

     // if we're displaying using another mode than WIREFRAME
     // we assign a material to the chair
     if(mode != WIREFRAME)
         assignMaterial(&reddishMaterial);
     chair.draw_model(mode);

     glPushMatrix();
     // we rotate the table to fit the chair
     // we scale it up a little bit on the z axis
     glRotatef(90, 0, 1, 0);
     glScalef(1, 1.7, 1);
     glTranslatef(-170.F, 0.F, 20.F);
     // if we're displaying using another mode than WIREFRAME
     // we assign a material to the table
     if(mode != WIREFRAME)
         assignMaterial(&redMaterial);
     table.draw_model(mode);

     glPopMatrix();

     glPopMatrix();
   }
}
\end{lstlisting}

Answer 1

Möglichkeit 1:Beamer-Dokumentenklasse verwenden

\documentclass{beamer}

\usepackage{listings}

\begin{document}
\begin{frame}[fragile]
\lstset{language=C++,
            basicstyle=\ttfamily,
            keywordstyle=\color{blue}\ttfamily,
            stringstyle=\color{red}\ttfamily,
            commentstyle=\color{gray}\ttfamily,
            morecomment=[l][\color{magenta}]{\#}
}
\tiny
\begin{lstlisting}

for(int i = 0; i < 4; i++){
   for(int j = 0; j < 2; j++){
     glPushMatrix();
     // We move the chair and table to their new location
     glTranslatef(-250.F + 220.F * i - 70.F * j,
     .0F, 20.F + 150.F * j);

     // if it's on the second row, we slightly rotate it
     float angle = j==0?-60.F:15.F*i;
     glRotatef(angle, 0, 1, 0);

     // if we're displaying using another mode than WIREFRAME
     // we assign a material to the chair
     if(mode != WIREFRAME)
         assignMaterial(&reddishMaterial);
     chair.draw_model(mode);

     glPushMatrix();
     // we rotate the table to fit the chair
     // we scale it up a little bit on the z axis
     glRotatef(90, 0, 1, 0);
     glScalef(1, 1.7, 1);
     glTranslatef(-170.F, 0.F, 20.F);
     // if we're displaying using another mode than WIREFRAME
     // we assign a material to the table
     if(mode != WIREFRAME)
         assignMaterial(&redMaterial);
     table.draw_model(mode);

     glPopMatrix();

     glPopMatrix();
   }
}
\end{lstlisting}
\end{frame}
\end{document}

Möglichkeit 2:Wenn Sie eine andere Klasse verwenden möchten, verwenden Sie nicht frames

\documentclass{report}
\usepackage{graphicx,parskip,bibunits,appendix,float,todonotes,pstricks,subfigure}
\usepackage[ruled] {algorithm2e}
\usepackage{url,amsmath,amssymb,fancybox,listings,pdfpages,caption,multicol,datetime,rotating, booktabs}
\usepackage[pagebackref=false,pdffitwindow=true]{hyperref}
\usepackage[bottom]{footmisc}
\begin{document}
%\begin{frame}[fragile]
\lstset{language=C++,
            basicstyle=\ttfamily,
            keywordstyle=\color{blue}\ttfamily,
            stringstyle=\color{red}\ttfamily,
            commentstyle=\color{gray}\ttfamily,
            morecomment=[l][\color{magenta}]{\#}
}
\begin{lstlisting}

for(int i = 0; i < 4; i++){
   for(int j = 0; j < 2; j++){
     glPushMatrix();
     // We move the chair and table to their new location
     glTranslatef(-250.F + 220.F * i - 70.F * j,
     .0F, 20.F + 150.F * j);

     // if it's on the second row, we slightly rotate it
     float angle = j==0?-60.F:15.F*i;
     glRotatef(angle, 0, 1, 0);

     // if we're displaying using another mode than WIREFRAME
     // we assign a material to the chair
     if(mode != WIREFRAME)
         assignMaterial(&reddishMaterial);
     chair.draw_model(mode);

     glPushMatrix();
     // we rotate the table to fit the chair
     // we scale it up a little bit on the z axis
     glRotatef(90, 0, 1, 0);
     glScalef(1, 1.7, 1);
     glTranslatef(-170.F, 0.F, 20.F);
     // if we're displaying using another mode than WIREFRAME
     // we assign a material to the table
     if(mode != WIREFRAME)
         assignMaterial(&redMaterial);
     table.draw_model(mode);

     glPopMatrix();

     glPopMatrix();
   }
}
\end{lstlisting}
%\end{frame}
