installinglistings
I've been trying to use the listings package, but whenever I try to install it I get the message:
! LaTeX Error: File `listings.sty' not found.
I'm new to LaTeX and I have no clue how to do anything. I'm using TexStudio.
Could someone walk me through how to fix this. I've seen many threads about the very same issue, but I simply don't understand what I have to do.
As @Gonzalo Medina has pointed out, wasysym is included im MiKTeX. Even if it wasn't, you should not manually place files in C:\Program Files (x86)\MiKTeX 2.8 -- either use the package manager, or place all necessary files in your working folder (as a temporary solution) or a local TEXMF tree.
One possible reason for the "permission denied" error you mentioned is that your operating system is Windows 7 and you try to run the package manager and/or the FNDB refresh as normal user. Run it as administrator instead -- this option should be selectable under (Right-click) Properties/Compatibility. (Those may not be the exact labellings -- I'm using a German Win7.)
I don't really know anything about listings or multicol and particularly haven't a clue as to why they complain so much about being put in a box (presumably to do with how multicol works its magic). So I went back to the original specification: to get a listings listing in a columnar setup within a TikZ node. I came up with the following solution. What seemed to be the key was to avoid precisely that situation that your code lands in: that something reads in the listing ahead of time and then resets it somewhere else. Several of the commands that I chose to use had a "read ahead" version, and I found that the code did not work if I chose that one. For example, I had to use a minipage instead of a \parbox.
Anyway, this will need tweaking I'm sure - particularly with regard to line widths - but it does seem to do the basic "put a 2-column listing in a TikZ node".
\documentclass{article}
\usepackage{listings}
\usepackage{tikz}
\usepackage{multicol}
\tikzstyle{sourcecodebox} = [
fill=white, draw=black, inner sep=1em, rectangle
]
\makeatletter
\lstnewenvironment{lstfigurelisting}[1][]{%
\tikzpicture
\node[sourcecodebox] (box)
\bgroup
\minipage{.75\textwidth}
\lstset{frame=none,#1}
}
{
\endminipage
\egroup;
\endtikzpicture
}
\makeatother
\begin{document}
Some code here:
\begin{lstfigurelisting}[multicols=2]
#!/usr/bin/env python
def main():
print "Hello, World!"
if __name__ == '__main__':
main()
\end{lstfigurelisting}
\end{document}

MiKTeX is capable of installing missing package on-the-fly through it's
texifyexecutable. However, manual installation is best done through the MiKTeX Package Manager:
