The above instructions do nada in my spacemacs, so I ignored those instructions.

The latest ghc release give errors like this:

I'm using ghc-mod and intero. What I would like to see is the actual error from ghc.

I'm using ghc-mod and intero

Wut? How is that possible in plain Spacemacs? AFAIK, they are exclusive.

[bravomikekilo]

me too
I use

1. the universal Linux Haskell platform
2. ghc-mod 5.6.0.0 build by the ghc8
3. the stack set to a ghc8 nightly build
   It is quiet wired that the warn the still okey.
   Some error can show up correctly ,for example parse error
   but when you make a new file and write |>
   module Main
   without a main function , the error become the "error:"
   I have a guessing that the missing error seem all have a \n after the error:
   so maybe this is the point because the old version of GHC produce those error message without \n

the new version seems solved this problem

I just upgrade the package from 105.21 , after the upgrade the problem seems solved , but I haven't
fully test yet

I mean I have ghc-mod and intero installed. I couldn't find any way to configure either, so Spacemacs will do whatever it wants.

I'm using 0.105.22

I had this issue after switching to GHC 8. Was fixed by upgrading spacemacs and related packages. Unless @alexanderkjeldaas still has issues we can close?

Please try to reproduce this issue using latest Spacemacs (master or dev) and latest version of all related packages (better to just update all of them 😸 ). Closing this as being potentially fixed on master / upstream. Let me know if it's not.
