I am trying to create a test suite for my Haskell/Cabal package using HUnit, and am getting the following error when I run cabal test:
matthew@matthew-Gnawty:~/backup/projects/apollo$ cabal test
Re-configuring with test suites enabled. If this fails, please run configure
manually.
Resolving dependencies...
Configuring apollo-0.1.0.0...
cabal: At least the following dependencies are missing:
hunit >=1.2 && <1.4
I have run 'cabal hunit' to install hunit. To check that it has been installed I have run "ghc-pkg list HUnit" which returns:
matthew@matthew-Gnawty:~/backup/projects/apollo$ ghc-pkg list HUnit
/var/lib/ghc/package.conf.d
HUnit-1.2.5.2
/home/matthew/.ghc/x86_64-linux-7.6.3/package.conf.d
HUnit-1.3.1.1
Why can't cabal configure properly?
I have tried:
To ensure that either the global (1.2.5.2) version or local (1.3.1.1) version is noticed by cabal by specifying the build-depends as:
build-depends: base >=4.6 && <4.7,
hunit >=1.2 && <1.4
in my [packagename].cabal file.
I have also noticed https://www.haskell.org/cabal/FAQ.html#runghc-setup-complains-of-missing-packages, and did not understand the explanation given there, and how the Setup.hs is relevant.
My Setup.hs file consists of only
import Distribution.Simple
main = defaultMain
I have tried adding 'import Test.HUnit' to the Setup.hs file:
import Distribution.Simple
import Test.HUnit
main = defaultMain
running 'cabal test' with this Setup.hs gives the same error.
