posix_other.nim(530, 3) Error: cannot 'importc' variable at compile time`

[Wh1teDuke]

Error:
../../Nim/lib/posix/posix_other.nim(530, 3) Error: cannot 'importc' variable at compile time
I don't know where the error in my project is, but it wasn't an issue before.

Culprit: #10016

Workaround: rm config/config.nims

Then I don't think anyone can reproduce it with that little information. It must have come from some module importing posix, but other than that I've no idea.

[Wh1teDuke]

@alaviss I'm checking what commit introduced the error. I think is related to #9153

[Wh1teDuke]

Issue introduced here #10016

[alaviss]

do you have any NimScript file in your project?

[Wh1teDuke]

I have a .nim.cfg file named the same as the main module.

closing this, feel free to re-open if you still have this issue.

This is most likely due to a mis-match between bootstrapping nim (csources) and what nim expects.
This should be fixed now that nim keeps track of which csources version is needed in a future proof way, see #17907 (comment) for details, which also explains how to bootstrap reliably.

(#15843 (comment) was also closed for similar reasons)
