[Tex/LaTex] Package nomencl not generating .nlo file

Question

For some reason when I process with pdflatex and work with makeindex -s nomencl.ist -o EncFor.nls EncFor.nlo
The nomenclature is just not showing up. Here is my code:

\documentclass{book}
\usepackage[english]{babel}
\usepackage{graphicx, imakeidx, afterpage}
\usepackage{mathtools, amsthm, epigraph, etoolbox, amssymb}
%\renewcommand{\qedsymbol}{$\blacksquare$}
\usepackage[utf8]{inputenc}
\usepackage{draftwatermark}
\usepackage[hidelinks]{hyperref}
\usepackage[toc]{glossaries}
\usepackage[intoc]{nomencl}

    For a set of data
    $$ \{ x_1,x_2,\ldots,x_n \} $$
    \begin{AMean}
    The arithmetic mean is defined\footnote{or can be deduced logically} as follows :
    \label{eq:Mean}
    \begin{equation}
        \label{eq:Arithmetic Mean}
        \bar{x}:=\frac{\displaystyle\sum_{i=1}^{n} x_i}{n}

    \begin{proof}
    This is not provable because it is a definition.

makeindex EncFor.glo -s nomencl.ist -o EncFor.nls
pdfLaTeX EncFor.tex

Answer 1

You forgot \makenomenclature in the preamble! If this command is missing, no .nlo file is generated and as a consequence, the makeindex -s nomencl.ist.... sequence fails, not producing the final .nls file.
