Crytpo for nhc

I have been trying to write a Crypto library and so far it works with ghc and hugs. Am I right in thinking I am going to struggle with nhc? It uses Word8 and Word64 heavily. For example, cipher block chaining relies on xoring Word64. I attach the library and a test program. I'd be grateful for any suggestions on how to make it work with nhc. Dominic Steinitz

Fw: [nhc-users] Problem installing nhc98 1.16 using bootstrap-from-C method

Sorry for the second message here - I should have said I just installed cygwin yesterday and it is v1.3.22-1. Also, I'm running on XP Pro. Thanks! -- Dave ----- Original Message ----- From: David Bakin To: nhc-users(a)haskell.org Sent: Wednesday, April 09, 2003 9:10 PM Subject: [nhc-users] Problem installing nhc98 1.16 using bootstrap-from-C method I'm having trouble building nhc98 using bootstrap-from-C - the following shows the error I'm getting.

Has anyone tried this? I don't think anyone has tried it before. Aside from the basic platform differences you can already guess: * Add .exe to executable filenames * Use \ as a directory separator instead of / * PATH uses ; instead of : the main obstacles will be: * The Makefiles assume some GNU extensions * The Top-level drivers are shell-scripts On the latter point, nhc98 (and hmake) have shell-script drivers to interpret arguments and call the various stages (pre-processor, Haskell compiler, C compiler, assembler, linker, etc.). Since native windows doesn't have the Bourne shell, you either need to haul in Cygwin's 'bash' (and associated tools like sed, cut, etc) just for that job, or re-code the scripts (perhaps in Haskell?).
