Hello all,

I know it is not probably good question to this list, but anyway, could anyone point me to some more detailed "how to" where is described building of Haskell Platform natively to 64bit Windows?

If you figure out how to do this, I would like to know as well. I could also benefit from 64bit Haskell on windows.

There is no port of GHC to 64-bit Windows yet. Various people have expressed an interest in having one, but it is a significant chunk of work to implement (plus extra work to maintain and build distributions), so we don't have any plans to do it in the short term.

You can track progress (or lack thereof) by adding your email to the CC on the ticket:

http://hackage.haskell.org/trac/ghc/ticket/1884

If you want to help out, join cvs-ghc@haskell.org and we can help with pointers to what needs to be done.

Cheers, Simon

Hi, Just to double check: that means, today it's not possible to generate 64 bit operations under Windows, including bit level .&., .|. a.s.o. (from Data.Bits), and this situation will stay like this for a while. I'm asking this because I'm currently writing a pure Haskell chess engine based on bitboards. The bitboards are 64 bit wide and the basic operations are critical for speed, which is always critical in chess engines. Then it looks I'll have to implement these operations in C and use FFI to link them. Nicu
