I have a new problem with the nomenclature. My preamble in the main file has the following lines:
\documentclass[ngerman,draft,table*]{sdqthesis}
\usepackage{nomencl}
\makenomenclature
\immediate\write18{%
makeindex -s nomencl.ist -o \jobname.nls -t \jobname.nlg \jobname.nlo%
}
.
.
.
And in the same main file I use the command:
\printnomenclature
Then in another file, which is inculded in the main file, I define after an equation:
\nomenclature{$P^{NOpt}$}{Elektrische Leistung der nicht optimierbaren Geräte}
After compiling no error message is show but the nomenclature cannot be found anywhere. Does anyone have a clue what I have to do.
I was adviced to post a new question with a link to the other question.

makeindexhad created file*.nlsand do the files*.nloand*.nlgexist? – Mensch Sep 27 '15 at 17:03
