-------------------------------------------- -- Haddock 2.8.0 --------------------------------------------
A new version of Haddock, the Haskell documentation tool, is out!
It doesn't install on Windows + MinGW:
cabal install --global haddock Resolving dependencies... Downloading haddock-2.8.0... : : [ 9 of 33] Compiling Haddock.Utils ( src\Haddock\Utils.hs, dist\build\Haddock\Utils.o )
src\Haddock\Utils.hs:435:8: parse error on input `import' cabal: Error: some packages failed to install: haddock-2.8.0 failed during the building phase. The exception was: ExitFailure 1 This concerns a line with a foreign import: #ifdef mingw32_HOST_OS foreign import ccall unsafe "_getpid" getProcessID :: IO Int -- relies on Int == Int32 on Windows #else getProcessID :: IO Int getProcessID = fmap fromIntegral System.Posix.Internals.c_getpid #endif Adding the line: {-# LANGUAGE ForeignFunctionInterface #-} to the top of file src\Haddock\Utils.hs helped.
