Abbreviations can't be generated

[nesliskender]

Hi everyone,

Thanks a lot for providing this template.

I have a small issue regarding the abbreviations. I create an abbreviation like this in glossary.tex file:

\newglossaryentry{NLP}{
name={NLP},
description={Natural Language Processing},
type=abbreviations
}

And try to add it to one of my chapter with \gls{NLP}, but it doesn't work. I see this message on the abbreviation page:

"This document is incomplete. The external file associated with the glossary ‘abbreviations’ (which should be called output.gls-abr) hasn’t been created. Check the contents of the file output.glo-abr. If it’s empty, that means you haven’t indexed any of your entries in this glossary (using commands like \gls or \glsadd) so this list can’t be generated. If the file isn’t empty, the document build process hasn’t been completed.

You may need to rerun LATEX. If you already have, it may be that TEX’s shell escape doesn’t allow you to run makeindex. Check the transcript file output.log. If the shell escape is disabled, try one of the following:
• Run the external (Lua) application: makeglossaries-lite "output"
• Run the external (Perl) application: makeglossaries "output"

Then rerun LATEX on this document. This message will be removed once the problem has been fixed."

I use Overleaf for the creating latex file and I couldn't see any file named "output.gls-abr". Does someona have the same problem and maybe help me with it?

Thanks a lot.
