I am not sure what is going wrong. I have not been using Haskell on windows. I am also copying this reply to haskell-cafe and libaries mailing lists. Does anyone know?
I get passed that error on Cygwin by installing it like this: $ cabal update $ cabal install --extra-include-dirs="c:\cygwin\usr\include" regex-posix However, when I try using regex-posix, I get: $ ghci GHCi, version 6.10.1: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done.
