Adding acronym in my document

Question

I have to add an acronym list in my document and for that I am using:

\usepackage[acronym,style=long3col]{glossaries}
\makeglossaries

and

\newacronym{LOWERCASE LABEL}{UPPERCASE LABEL}{THE FULL TERM}\par
\printglossary[type=\acronymtype,title=Acronyms]

However I am getting an error:

\newacronym{LOWERCASE LABEL}{UPPERCASE LABEL}{THE FULL TERM}\par
\printglossary[type=\acronymtype,title=Acronyms]

Please can someone tell me what's wrong with my code. Please find the code below:

\documentclass[12pt,MSc,wordcount,oneside,anon, left= 40mm, right = 20mm, top = 20mm, bottom = 20mm]{muthesis}
\usepackage{hyperref}
\usepackage{fancyhdr}
\usepackage{color}
\usepackage{eucal}
\usepackage{graphicx}
\usepackage{etoolbox}
\usepackage{float}
\usepackage{longtable}
\usepackage{tabularx}
\usepackage{multicol}
\usepackage[justification=centering]{caption}
\usepackage[acronym,style=long3col]{glossaries}
\makeglossaries
\usepackage{textcomp}
\usepackage{enumerate}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{pifont}
\newcommand{\cmark}{\ding{51}}%
\newcommand{\xmark}{\ding{55}}
\usepackage{cleveref}
\graphicspath{ {pics/} }
\setlength{\parindent}{4em}
\setlength{\parskip}{1em}
\renewcommand{\baselinestretch}{1.5}
\setcounter{secnumdepth}{4}
\begin{document}
{
\newacronym{LOWERCASE LABEL}{UPPERCASE LABEL}{THE FULL TERM}\par
\printglossary[type=\acronymtype,title=Acronyms]
\begin{titlepage}
\begin{center}
\vspace*{1cm}
}
\bibliographystyle{ieeetr}
%ieeetran}
\bibliography{references}
%\end{flushleft}
\end{document}

Answer 1

Here are some comments on your code:

1. hyperref should be loaded last with a few exceptions.

2. \newacronym should be used in the preamble of your document, after \makeglossaries. If you are going to define many entries it should be preferable to write them in a separate .tex file and include the file with \input{...} or better \loadglsentries{...} (again, after \makeglossaries)

3. You have a \begin{titlepage} without its corresponding \end{titlepage}.

4. There is a group starting after \begin{document} and ending after \vspace*{1cm} that does nothing but trouble.

5. Finally you have to use an acronym in order to print something. Remember that the compilation chain should be something like:

   pdflatex mydoc.tex

   makeglossaries mydoc

   pdflatex mydoc.tex

(pdflatex could be changed for your favorite TeX flavor)

An example on how to add acronyms to your document is the following

\documentclass[12pt,MSc,wordcount,oneside,anon, left= 40mm, right = 20mm, top = 20mm, bottom = 20mm]{muthesis}
\usepackage{textcomp}
\usepackage{enumerate}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{pifont}
\usepackage{fancyhdr}
\usepackage{color}
\usepackage{eucal}
\usepackage{graphicx}
\usepackage{etoolbox}
\usepackage{float}
\usepackage{longtable}
\usepackage{tabularx}
\usepackage{multicol}
\usepackage[justification=centering]{caption}
\usepackage{hyperref}
\usepackage[acronym,style=long3col]{glossaries}
\makeglossaries
\newacronym{svm}{SVM}{Support Vector Machine}
\newcommand{\cmark}{\ding{51}}%
\newcommand{\xmark}{\ding{55}}
\usepackage{cleveref}
\graphicspath{ {pics/} }
\setlength{\parindent}{4em}
\setlength{\parskip}{1em}
\renewcommand{\baselinestretch}{1.5}
\setcounter{secnumdepth}{4}
\begin{document}
\printglossary[type=\acronymtype,title=Acronyms]
\chapter{test}
Hello world!
First use of acronym \gls{svm}. Second use \gls{svm}
\end{document}
