Re: setting up my own channel (for some personal packages)

[Edouard Klein]

Hi,

I am not sure, but here is my try:

I cloned your channel2 repo, and saw in emacs-hide-comnt.scm:

(define-module (gnu packages emacs-hide-comnt)

Modules names in Guile (in all schemes ?) must match the path, so either
put emacs-hide-comnt.scm in gnu/packages, or change the above line to:

(define-module (emacs-hide-comnt)

See that urweb.scm starts with:
(define-module (urweb)

My interpretation is that the error message means that the
emacs-hide-comnt module was not found where it was looked for, i.e. in
gnu/packages.

This may not be the only problem, but it is worth a try.

Good luck :)

Cheers,

Edouard.
