Latex: Listings with monospace fonts

Question

This is what the code looks in Xcode.

And this in my listing created with texlive.

And yes I used basicstyle=tfamily . Having looked at the manual of listings I haven't found anything about fixed-with or monospace fonts..

Example to reproduce

documentclass[
  article,
  a4paper,
  a4wide,
  %draft,
  smallheadings
]{book}

% Packages below
usepackage{graphicx}
usepackage{verbatim} % used to display code
usepackage{hyperref}
usepackage{fullpage}
usepackage[ansinew]{inputenc} % german umlauts
usepackage[usenames,dvipsnames]{color}
usepackage{float}
usepackage{subfig}
usepackage{tikz}
usetikzlibrary{calc,through,backgrounds}
usepackage{fancyvrb}
usepackage{acronym}
usepackage{amsthm} % Uuhhh yet another package
VerbatimFootnotes % Required, otherwise verbatim does not work in footnotes!
usepackage{listings}

definecolor{Brown}{cmyk}{0,0.81,1,0.60}
definecolor{OliveGreen}{cmyk}{0.64,0,0.95,0.40}
definecolor{CadetBlue}{cmyk}{0.62,0.57,0.23,0}
definecolor{lightlightgray}{gray}{0.9}

showspaces=false,                       % Dont make spaces visible
showtabs=false,                         % Dont make tabls visible
columns=flexible,                       % Column format
morekeywords={__global__, __device__},  % CUDA specific keywords
}

egin{lstlisting}
    As[threadRow][threadCol] = A[
        threadCol + threadRow * Awidth   // Adress of the thread in the current block
        + i * BLOCK_SIZE                 // Pick a block further left for i+1
        + blockRow * BLOCK_SIZE * Awidth // for blockRow +1 go one blockRow down
    ];
end{lstlisting}

Answer 1

The problem is the columns=flexible option. Remove it and it looks like you want it to look. At least, if there is no actual reason for you to use it. If there is, there is no way to have the monospaceness of your snippet to look like in Xcode :).
