"Needed for compilation but not listed in your .cabal file's other-modules"

Hi!

Thank you for the report.

I think I've found the problem.

These modules are needed for compilation but not listed in your .cabal file's other-modules: is a warning, not an error (https://github.com/ghc/ghc/blob/21f0f56164f50844c2150c62f950983b2376f8b6/compiler/main/GhcMake.hs#L205). It seems that haskell-code-indexer complains because of the -Werror flag that makes all warnings fatal (https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/using-warnings.html?highlight=werror#ghc-flag--Werror).

I've removed -Werror flag from the list of options for GHC.

Can you try 67d0714?

Hmm, that commit doesn't build for me:

Hmm, of course that isn't to do with that, it's my fault for moving the source directory! Apologies.

[pwaller]

It's working! Awesome, thanks.

[alexwl]

Cool!

If you have any ideas or suggestions on how to improve the tool, I'd love to hear them.
