Re: [Haskell-cafe] building unix package on windows
Those headers simply do not exist under windows. There's a reason it's called 'Unix' :P Perhaps mingw32 or cygwin could help, as those packages make an attempt at emulating (so to speak) the unix environment.

Next year I'll be working on a project for my undergraduate computing course at UNSW that will involve getting GHC to target the Nintendo DS. It'll require cross-compilation, because the DS isn't powerful enough to actually run GHC (4M main ram and a 66MHz processor). It'll also require that I significantly strip down the runtime system, as the current RTS won't fit in 4M and leave any left over for the main application. I'll be documenting the whole process, but I won't be starting until next year... Jeremy ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Think about this: map (+1) [1..10] What should it do? How about: f 1 2 3 Should that be f (1 (2 3)), or ((f 1) 2) 3?

Actually GCC will happily optimise this away in almost all cases.
