--------------------------------+-------------------------------------------
I get the following error when building the time library using ghc-6.6.1
and Cabal-1.1.6.2.
{{{
C:\Temp\time>runhaskell Setup.hs configure
Setup.hs:17:29:
Couldn't match expected type `GHC.IOBase.ExitCode'
against inferred type `()'
Expected type: Args
-> Bool
-> PackageDescription
-> LocalBuildInfo
-> IO GHC.IOBase.ExitCode
Inferred type: Args
-> Bool
-> PackageDescription
-> LocalBuildInfo
-> IO ()
In the `runTests' field of a record
In the expression:
defaultUserHooks
{confHook = add_Win32_dep $ (confHook defaultUserHooks),
runTests = runTestScript}
}}}
I solved it by changing the type signature of runTestScript and removing
the maybeExit function call from the body:
{{{
import GHC.IOBase
...
runTestScript :: Args -> Bool -> PackageDescription -> LocalBuildInfo ->
IO GHC.IOBase.ExitCode
runTestScript _args _flag _pd _lbi
= withCurrentDirectory "test" $ system "make"
}}}
Then, the Setup.hs script compiles but I get a dependency problem
{{{
C:\Temp\time>runhaskell Setup.hs configure
Configuring time-1.1.1...
configure: Dependency Win32-any: using Win32-2.1.1
configure: Dependency base-any: using base-2.1.1
Setup.hs: cannot satisfy dependency old-locale-any
}}}
I solved it with removing that dependency from the time.cabal file.
Last issue: at installation HsTimeConfig.h is missing (copied it from
ghc-6.6.1 source).
I don't know to which extent those problems are related to my specific
installation. Looks like the user hooks signature has changed in the
latest versions of Cabal.
