[Haskell-cafe] Fwd: Error instaling Happstack on Windows - cabal bug?

[Stephen Tetley]

Hi all

A cursory look at Happstack.Crypto.MD5 shows it uses -fvia-c:


{-# LANGUAGE BangPatterns #-}
{-# OPTIONS_GHC -funbox-strict-fields -fvia-c -optc-funroll-all-loops
-optc-O3 #-}
--
-- Module      : Happstack.Crypto.MD5
-- License     : BSD3
........


GHC (on Windows) comes with perl so it shouldn't need installing again.

As an expedience, one could try removing the OPTIONS_GHC pragma to see
if it compiles at least (there may be other modules that use fvia-c
too).

Best wishes

Stephen
