OK, I forgot the —enable-tests flag to cabal install…
However, there seems to be some strange interactions I do not understand fully with the test section of cabal.
Here is the cabal file:
name: Thermometre
version: 0.1.0.0
synopsis: synopsis
-- description:
license: PublicDomain
license-file: LICENSE
author: Black
-- maintainer:
-- copyright:
-- category:
build-type: Simple
cabal-version: >= 1.8
library
hs-source-dirs:
src
exposed-modules:
Thermometre
build-depends:
base == 4.*
test-suite spec
type:
exitcode-stdio-1.0
ghc-options:
-Wall -Werror
hs-source-dirs:
test
main-is:
Spec.hs
build-depends:
base == 4.*
, Thermometre
, hspec >= 1.3
When I remove the test-suite section and open src/Thermometre.hs I got errors highlighting which is fine. C-c C-t does not give me types however ('Cannot guess type’ message).
When I leave the test-suite section then opening Thermometre.hs gives me a package error: ‘cannot satisfy -package Thermometre’ as there is a dependency from the tests to the main library.
How can I solve that?
Thanks

I upgrade my emacs configuration with latest ghc-mod and all of sudden nothing works (again). When I try to load a .hs file from a project I got the first line highlighted with the error "cannot satisfy -package spec" and I cannot got type, info or doc from that file. Also I do not have anymore syntax errors highlighting I used to see.
As this message suggests, you need to install spec for testing.
% cabal install spec
# I don't know what the spec package is. A typo for hspec?
This is because ghc-mod obtains dependency for executables, libraries *and* testing.
In general, % cabal install --only-dependencies would help you.
