Re: Re: Retrieving the "include" directory for Emacs Modules

[Marco Antoniotti <marcoxa@gmail.com>]

Sorry Eli

your solution is not portable and it doesn't work on Mac and Windows (29.2)

On Mac the following works

ELISP> (expand-file-name "../include" data-directory)
"/Applications/Emacs.app/Contents/Resources/include"

On Windows the include folder is "higher" up.
"C:\Program Files\Emacs\emacs-29.2\include\"

Given that people (like me) are experimenting with emacs modules, I'd lobby
for the introduction of a 'include-direcotry' variable.

All the best

Marco
