How to add IEEEtran.cls to be read automatically?

Question

I am using a MacOS and I want to copy the IEEEtran.cls file into the latex directory such that it is read automatically.

I have a file in the directory /opt/local/share/texmf-texlive-dist/tex/latex/IEEEtran/IEEEtran.cls

But when I do \documentclass{IEEEtran} it fails to read the file.

Please help if anyone has seen this.

One possibility is that the directory you have put the class file is not in the input path search list. This can be defined using the TEXINPUTS environmental variable e.g.

export TEXINPUTS=.:/somepath/lib/latex: 

would be used to have it search in /somepath/lib/latex as well as current directory. I have such a directory for odd bits of nonstandard LaTeX configuration and class files.
