bug#43969: 28.0.50; jupyter-emacs package fails to load on feature/native-comp

[Ricardo E. Gonzalez]

To reproduce the problem, start emacs and native compile the
jupyter-emacs package (I am using version 20200417 from elpa).  Quit
emacs and start it again (emacs -Q) and load the jupyter-channel.elc
file.

The file fails to load and I get the following error message:

Loading packages/28.0/elpa/jupyter-20200417.1907/jupyter-channel.elc (native compiled elisp)...
load-file: Symbol’s value as variable is void: jupyter-channel

If I remove the native-compiled file from the eln cache, the file is
loaded correctly once (subsequent loads will fail again).

bug#43969: 28.0.50; jupyter-emacs package fails to load on feature/native-comp

I hit the same bug 6 month ago.
This is an error in emacs-jupyter and not native-comp.

I made a pull request to fix it here:

https://github.com/nnicandro/emacs-jupyter/pull/248

You can check this out locally and then it should work.

Cheers,
  Daniel

Hi Daniel,

thanks for commenting, I agree too this should be fixed on emacs-jupiter
side.  Maybe they just need a ping? :)

I'm closing this as there's no action we can take on our side, happy to
reopen in case.

Thanks!

  Andrea
