[Tex/LaTex] Nomenclature list not getting updated

nomenclnomenclature

I am using \usepackage{nomencl} to define a list of symbols…
For example 

\nomenclature[B]{$\varepsilon$}{Permittivity \nomunit{$Farads/cm$}}
\nomenclature[B]{$a$}{Lattice constant\nomunit{$\AA$}}

Now I want to add new symbols, but I do not understand why my pre-existing list is not getting updated in the output file..

Can you please help?

I already tried deleting auxillary file, but it does not help

Here is a working example: (please note the package adsphd can be downloaded here: https://people.cs.kuleuven.be/~wannes.meert/adsphd/)

Best Answer

I finally find the solution.

I am using TeXstudio.

Go to Option--> Configure Texstudio --> Commands In the field of Makeindex write the following:

makeindex.exe %.nlo -s nomencl.ist -o %.nls

I have no clue what it means. But it works!
