Showing List of Acronyms without a result

Question

I'm trying to create a list of acronyms with Glossary. My main .tex use a \documentclass{Dissertate} Before trying using Glossary I had a .tex where manually added the acronym. To print on my document I used

\newcommand{\acrnyms}{
    \phantomsection
    \addcontentsline{toc}{chapter}{Lista degli acronimi}
    \chapter*{Lista degli acronimi}
    \input{frontmatter/abbr.tex}
}

and then I printed it with

\acrnyms

Now, I would like to use my .tex file to print the list created by Glossary. I've added on my .cls file

\usepackage[acronyms]{glossaries}
\makeglossaries

after hyperref as indicated in the documentation of the package and I've added \newacronym{3gpp}{3GPP}{3a Generazione Partnership Project} after that Once in my .tex file (the one that was used to manually write the acronymous) I've used the code \printglossary[type=\acronymtype] but it doesn't show anything

Where I'm doing wrong?

Answer 1

The problem was I had to copy

\addcontentsline{toc}{chapter}{List of Acronyms}

before \printglossary[type=\acronymtype] to print it
