"Local variables entry is missing the suffix" error when installing packages

[rzikm]

What did you expect to happen?
Using cc module, or *-posframe packages and running doom sync should work.

What actually happened?
Error during compilation of the affected packages(s),

error: (Local variables entry is missing the suffix)

full output available below.

Additional details:
Currently running emacs 26.3, but I have tried 27 and 28 with same result.
I have tried reinstalling doom from scratch.
On my work PC, I have exactly the same setup, but there it works correctly. I was unable to find any similar issues on the internet.

running doom -d sync produces following output

[newmaidumosa]

is there any work around for this? I would like to get lang cc up and running. Thanks.

[hlissner]

Sorry for the long delay, I've finally zeroed in on the cause of this. The problem is that some packages have hard-coded a windows-unfriendly line encoding at the end of their packages.

irony-eldoc and helm-posframe are two known packages with these file local variables:

;; Local Variables:
;; coding: utf-8-unix
;; End:

utf-8-unix should be utf-8. This will need to be brought up upstream.

This appears to have been reported before.

[hlissner]

I made a pull request upstream to fix the issue with helm-posframe, specifically, and it was merged, so @rzikm's original issue should be resolved. I'll keep this issue open until

1. I've updated Doom's documentation to mention this workaround for Windows users:

   git config --global core.autocrlf true

2. My PRed for irony-eldoc is merged: Don't specify a line-ending encoding explicitly ikirill/irony-eldoc#13

[nmillington]

Thank you, have just encountered this bug today. Switched on lsp mode but will get the work around going.

[hlissner]

As of 0443eeb (and ikirill/irony-eldoc#13 and tumashu/helm-posframe#9) this should be resolved (in irony-eldoc and helm-posframe's cases, at least). I haven't yet mentioned it in the docs, but I'm working on a documentation redesign and will include it with that. I'll close this for now, but thanks for bringing it to my attention!
