I have tried this with ghc 7.0.3 and ghc 7.4 on Arch Linux with ghc-mod 1.10.* . I cannot get the ghc-mod check command to produce any output. Is this a symptom of something common. ghc-mod lint works fine.

Can you try it with GHC 7.0.4? I don't have GHC 7.0.3 anymore. I would like to see if the source of the problem is from GHC version.

Tried it with 7.0.4 -- Everything seems to be fine using this version of GHC.

EDIT: I've been having problems with ghc-mod on ghc-7.4.1 and solved them. Still not sure what was the reason, but if you are having an issue after upgrading ghc, try issuing "cabal clean" then "cabal configure" in your project directory (assuming it is cabalized) and remove the cabal-dev directory, if you have it. Hope it helps.
