[Haskell-cafe] How to set ghc options while building Setup.hs in cabal package?

[Daniel Díaz Casanueva]

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
