Eval error on fresh install for MacOs caused by json-process-client `Symbol's value as variable is void`

[vitorqb]

Hi!

Today I just installed indium on a fresh emacs installation on MacOs and when trying to (require 'indium) it gave me the following error:

Eval error ***  Symbol’s value as variable is void: json-process-client--application-create

After a little of debugging I found that for some reason the byte-compiled version of the json-process-client library was throwing this error, but the non compiled version works just fine. So I rm json-process-client.elc, keeping only the .el file, and it works just fine.

I was wondering (a) if that's not happening to anyone else and (b) if you know what could be causing this issue (if it's a library bug or something to do with MacOs).

Versions: GNU Emacs 27.1 (build 1, x86_64-apple-darwin19.5.0, NS appkit-1894.50 Version 10.15.5 (Build 19F101)) of 2020-08-27 macOS Catalina 10.15.7 indium 20200116.1247 json-process-client 20190827.1858

PS: I would have opened a bug for json-process-client but I can't seem to access it's gitlab repository at https://gitlab.petton.fr/nico/json-process-client

I'm seeing this on a fresh install on Ubuntu 20.04 as well. Deleting the byte-compiled json-process-client.elc fixed the problem for me. Thanks @vitorqb.

My installation has:

• emacs 27.1
• nvm version v8.17.0
• indium version 20201103.2040
• stock configuration in .indium.json

{
    "configurations": [
        {
            "name": "Gulp",
            "type": "node",
            "program": "node",
            "args": "./node_modules/gulp/bin/gulp.js",
            "inspect-brk": true
        }
    ]
}

@DamienCassou any idea what's going on?

[DamienCassou]

I don't know, sorry.

I just tried with a fresh vanilla Emacs 27.1, installing Indium from MELPA, and I cannot reproduce the issue.

[jacksonbenete]

GNU Emacs 27.1 (compiled on Ubuntu 20.04.1 LTS)
node v15.7.0
npm 7.5.1
chromium 88.0.4324.96 snap
indium 2.1.7

I'm having this same error both trying with node and chromium. But I prefer not to delete anything from my Emacs for now...

I've got the same issue

I also have the same problem (installing indium in doom-emacs).

For me what fixed the problem was adding (require 'cl-lib) to the top of the json-process-client.el file and recompiling.

@DamienCassou Maybe this is the fix, but I only have a very shallow elisp knowledge.

[DamienCassou]

What you suggest seems reasonable @bergmannf. I sent a PR for this https://gitea.petton.fr/nico/json-process-client/pulls/1. Thank you!

@NicolasPetton I don't have write access to https://gitea.petton.fr/nico/json-process-client. Can you please merge the PR?

[bergmannf]

I just updated my packages when using doom and with version 1.0.0 of json-process-client I don't see the error anymore.

If someone else that maybe isn't using an emacs distribution is also not seeing it anymore I think this Issue can be closed.
