@TakSuyu Can you try again with the latest MELPA build?
Still giving me the same error; is there anything I can type in for some debug information?
It didn't recheck when I opened the file. Works just fine once I rewrote the function.
Reopened the file and the error came back.
Here is the piece of code that throws the error
import Control.Lens (makeFields)
data Player
= Player
{ score :: Integer
, hand :: Hand
, stolenMelds :: [Meld]
, discardPile :: Pile
}
deriving (Show)
makeFields ''Player -- The one liner from lens
@TakSuyu That is strange because we do actually extract the language extensions. Can you show the output of C-c ! C-c haskell-ghc
in the affected buffer?

Perhaps you intended to use TemplateHaskell

For whatever reason ghc and ghc through stack (I went ahead and tried using the same command but haskell-stack-ghc
instead) Both give me those errors. However from CLI, even stack build --pedantic
(which turns on -Wall and -Werror) compiles no problem.
@TakSuyu Do you actually have Flycheck Haskell enabled? There are no options at all in your GHC command, even though there are some that are always set by Flycheck Haskell and definitely must appear there if the package is correctly setup.
spacemacs pulls it in as a dependency for the layers I'm using. Maybe it's configured incorrectly?
Yep they misconfigured the hook. Sorry for wasting your precious time.
My cabal file contains
default-extensions: TemplateHaskell
for the project which enables it for any exposed module.However flycheck gives me this error on a naked expression when the Pragma isn't at the top of the file.
