Landscape view, two separate columns with listings over multiple pages

Question

I want to compare two codes in two different languages in latex. I use lstlisting for both of them and then I want to see them side by side. I archived this using minipage environment but my listings are bigger than one page so they are overlapped. Also I have a strange empty page before listings. Multicolsenvironment doesn't allow me to see listings side by side. Anybody know solution?

I use code like this

\begin{landscape}
\noindent\begin{minipage}{.45\columnwidth}
  \begin{lstlisting}[caption=code 1,frame=tlrb]{Name}
    void code()
    {
    }
  \end{lstlisting}
\end{minipage}\hfill
\begin{minipage}{.45\columnwidth}
  \begin{lstlisting}[caption=code 2,frame=tlrb]{Name}
    void code()
    {
    }
  \end{lstlisting}
\end{minipage}
\end{landscape}

This is how it looks if i use paracol

Welcome to TeX.SX! Maybe you can make use of the paracol package as already suggested in the comments on this related question: side-by-side inputlisting in landscape over multiple pages](https://tex.stackexchange.com/q/377797/134144)[ — leandriis, Jun 29 '19 at 21:16

Unfortunately my ides using paracol only seems to work in portrait pages. Would that be an option for you? — leandriis, Jun 30 '19 at 16:26

It turns out that paracol is incompatible with pdflscape and IIRC listings can't break pages. You can use paracol to create a side by side two page layout, but it leaves the remainder of the right page blank.

\documentclass{article}
\usepackage{listings}
\usepackage{paracol}
\usepackage{lipsum}% MWE only
\usepackage{showframe}% MWE only

\globalcounter{lstlisting}% if you want different caption numbers

\begin{document}
\begin{paracol}[1]{2}
  \begin{lstlisting}[caption=code 1,frame=tlrb]{Name}
    void code()
    {
    }
  \end{lstlisting}
\switchcolumn
  \begin{lstlisting}[caption=code 2,frame=tlrb]{Name}
    void code()
    {
    }
  \end{lstlisting}
\end{paracol}
\lipsum[1-8]
\end{document}

It is also possible to store lstlisting in a savebox and use adjustbox to crop it into page sized chunks. See cropping boxes and boxing lstlisting.
