[NorfairKing]

Command: stack build --work-dir /home/syd/whatever/.stack-work
Stderr:
option --work-dir: InvalidRelDir "/home/syd/whatever/.stack-work"

Please see #2721 (comment). If @mgsloan is about, could you further elaborate on why this is?

We could improve the error message?

@lwm Thank you for the quick response.
If it's a known limitation, it might be nice to direct the user to an explanation of why that is.

Closing this is in the meantime.

I looked around and found this comment from @borsboom - #1178 (comment)

I've made it output more in the error message:

option --work-dir: InvalidRelDir "../test"
Note that --work-dir must be a relative child directory, because work-dirs outside of the package are not supported by Cabal.
