stack ghc error "Invalid Option `--make`

I am learning Hakyll a library in Haskell. I need to run

ghc --make site.hs

However, I instlled ghc with Stack so I can no longer run ghc but instead stack ghc

$ stack ghc --make site.hs
Invalid option `--make'

How am I supposed to compile my site.hs ??

Solution

  • Stack is interpreting your --make as being an option to Stack, not to the GHC subcommand. In order to tell Stack "I'm done giving you options, the rest is for the subcommand," you can use a --, e.g.:

    stack ghc -- --make site.hs
