nomencl latex won't show output - indexing

Question

\documentclass[9pt,conference,a4paper,twocolumn]{IEEEtran}
\usepackage{cite}
\usepackage{amsmath,amssymb,amsfonts}
\usepackage{algorithmic}
\usepackage{graphicx}
\usepackage{textcomp}
\usepackage{xcolor}
\usepackage{float}
\usepackage{lscape}
\usepackage{titlesec}
\usepackage{nomencl}
\makenomenclature
\begin{document}
\nomenclature{$k$}{set of hourly intervals}
\printnomenclature
\end{document}
I am trying to run this nomenclature code using TexStudio. I get error everytime, even if I already specified the makeindex as what I read from other reviews.
Here is what I specified:
makeindex (arb).nlo -s nomencl.ist -o (arb).nls
NOTE: where arb is the filename of my tex.
Everytime I ran the code, there are no errors. However, when I check via TOOLS/INDEX ,the errors are:
Process started: makeindex (arb).nlo -s nomencl.ist -o (arb).nls
Input index file (arb).nlo not found. Usage: makeindex [-ilqrcgLT] [-s sty]
[-o ind] [-t log] [-p num] [idx0 idx1 ...]
Process exited with error(s)
THANKS hopefully for the help

Answer 1

The titlesec package does not work in combination with the IEEEtran document class. During compilation it causes the error Undefined control sequence. \ttl#extract\subparagraph. Without an successfully tex run first, makeindex will not have the necessary information to create the index.
Once this problem is fixed, the nomenclatur can be generated with
makeindex ⟨filename⟩.nlo -s nomencl.ist -o ⟨filename⟩.nls

\begin{document}
test
\nomenclature{$k$}{set of hourly intervals}
\nomenclature{$d$}{set of daily intervals}
\printnomenclature
\end{document}

Answer 2

makeindex %.nlo -s nomencl.ist -o %.nls -t %.nlg
I have somehow solve this problem after various tries, I change the index which is above and it ran smoothly without errors in TeXStudio even if titlesec package is use.
NOTE: To add multiple nomenclatures, every time you encode the nomenclature, test index via Tools then RUN. it will solve the mentioned problems.
