I used to take a look at cabal files from projects that I've used and found to work. For example, IHaskell uses a lot of extensions [1]. [1]: https://github.com/gibiansky/IHaskell/blob/master/ihaskell.cabal#L122-L126 On 9 July 2015 at 21:32, Imants Cekusins <imantc@gmail.com> wrote:
Thank you Sumit.
This is how far I got:
if I put this right after hs-source-dirs:
default-extensions: FlexibleInstances
, it works: ghc asks for MultiParamTypeClasses option.
However if I add FlexibleInstances, MultiParamTypeClasses - either separated with comma or on the next line, the compiler parses .cabal and tries to build however prompts for FlexibleInstances again.
How would I specify >1 option?
