Problem with haskell process load file on Windows10

[tonyfloatersu]

Platform Information:

• Windows 10
• Haskell Platform 8.0.1
• Emacs 25.1

The problem is weird, when I just want to use haskell-process-load-file for a small piece of haskell code like this:

module CalcInptType ( Expr (..), Ops (..), Parse ) where

data Expr = Lit { value    :: Int }
          | Var { variable :: String }
          | Op { operate   :: Ops
               , express1  :: Expr
               , express2  :: Expr }
          deriving (Eq, Show)

data Ops = Add | Sub | Mul | Div | Mod | Def | Frc
         deriving (Eq, Show)

type Parse a b = [a] -> [(b, [a])]

Then here goes the error in the Message buffer.

error in process sentinel: haskell-process-prompt-restart: Wrong type argument: stringp, nil
error in process sentinel: Wrong type argument: stringp, nil

This kind of problem only happen on Windows, I checked in Linux and everything goes smoothly.

Then I use the debug-on-error to check, here goes the Backtrace debug buffer, a large chunk of message...

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

  string-match("You need to re-run the 'configure' command." nil)

Thank you for your haskell-mode, I like it very much, I hope I can help here.
(Sorry for my lame English since I am not native speaker... This is also my first ISSUE submitted. : ) )

[tonyfloatersu]

I guess this is something from different operation system, or different haskell-platform on different system...

[tonyfloatersu]

I checked again, with same haskell platform and same emacs configuration on my mom's computer with windows 10, it worked. I guess it is caused by the windows 10 update, maybe it is quite hard to hack.

[tonyfloatersu]

My current windows version is 10.1.15063 and it just does not work.
My mom's windows version is 10.1.14393 and it works.

[tonyfloatersu]

Roll back to version 10.1.14393, then everything get back to work again.
Weird, I leave these comments here, in case someone may need it.

[gracjan]

Did you mean to reopen it?

[tonyfloatersu]

Eh...yeah, I think we should reopen it, based on some reasons:

• The windows system have to update itself to defend the bitcoin virus.
• Just rolling back the system version seems to be escaping from a true solution.

So the problem still exists, unfortunately. '_>'
(Sorry for bothering again, I have to apologize for my closing this issue without careful consideration.)

[zelinskiy]

Having the same issue on 10.1.15063
Haskell platform version is 8.0.1

[ryukinix]

My emacs freezes on open any .hs file and calling haskell-mode. BTW, run-haskell exits too with error 66.

[vasanthaganeshk]

@ryukinix run-haskell uses inferior-haskell-mode. That mode is deprecated.

[ryukinix]

Thanks for the information, @vasanthaganeshk! But how I should call the ghci from emacs?

[vasanthaganeshk]

@ryukinix, M-x haskell-process-load-file or C-c C-l, to start the repl. By the way, haskell-interactive-mode is a little buggy and I'm working on improving it (in a fork).

Try haskell-interactive-switch.
