Re: [O] ob-haskell evaluation needs inf-haskell but it does not exist

[address@hidden]

I setted `haskell-process-type` to 'ghci.

I evaluated a simple haskell src block, but it reports I need have a `*haskell*` inferior. Then I executed command [M-x run-haskell].

Then I get error:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)

You probably need to set haskell-process-type to ghci. If that works, please let me know and I'll update the answer on SO.
