For the first part
$ cat foo.hs module Main (main) where
import Language.Haskell.Exts
main :: IO () main = print $ readExtensions "BangPatterns"
$ ghc --make foo.hs
foo.hs:3:8: Could not find module `Language.Haskell.Exts': Use -v to see a list of the files searched for.
So same error. This isn't just limited to HSE though, it can't find packages like random,time etc either. Keeps reinstalling them on every cabal install.
Borked compiler, then, it seems. Does it work when you pass -package flags on the command line instead of using --make? It looks a bit as though neither cabal nor GHC can parse the output of ghc- pkg.
And the second part,
Ghc-pkg check doesn't return anything, so I assume it thinks everything's fine.
Full output of my ghc-pkg list is below, and as you can see in the user packages, it's reinstalling every and shadowing those packages everytime. I could just rebuild everything including the compiler and that should fix it, but it's kinda odd that it got in this state.
