Hi.

I haven't tried myself, but perhaps the OPTIONS_GHC pragma will do what you want. Just add

{-# OPTIONS_GHC -Wall #-}

to the beginning of your Setup.hs file.

More info: https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/using.html#source-file-options

I hope that helps.

Best,
Daniel

Hi,

I have some code in Setup.hs in a cabalized project. I'd like them to
be warning-free. But I could not find a way to set -Wall.

I tried ghc-options in ~/.cabal/config. But seems like it did not kick in.

```
/bin/ghc --make -fbuilding-cabal-package -odir
