Re: Re[2]: [Haskell-cafe] Using of C constants in Haskell sources; Determining compilation environment (Unix vs Windows)

Hi

I would *guess* that hsc2hs is always distributed with ghc. I know it is on Linux and BSD -- I am not sure about Windows. It is.

If you want to support hugs as well, then they would need hschs-hugs installed. Debian includes that with hugs by default -- not sure about anyone else. Windows certainly does, I think its in the standard Hugs make scripts.

Hugs always has cpphs available, but doesn't provide a cpp. GHC doesn't ship with cpphs, probably for license reasons. However cpphs can be used used to simulate cpp on Unix (using cpphs.compat) and hopefully soon on Windows with a --cpp flag (although not yet). Cabal should take care of cpp on all platforms by using the distributed one though. Thanks Neil
