Re: UEFI Driver/Application

[Rafael Machado <rafaelrodrigues.machado@gmail.com>]

Hi Ivan

You need to add the declaration of ShellLib at the Nt32Pkg dsc file.
Other .dsc files maybe usefull to check how to do that. Maybe you will need
to add other packages after adding the ShellLib. So other errors may arise
until you add all the required packages.
