support for imported doubles/floats?
by Mark Wotton 18 Aug '09

18 Aug '09

maybe a known issue, but I can't seem to import functions involving C floats or doubles: 17:33[1] ~ % cat RubyMap.hs {-# LANGUAGE ForeignFunctionInterface #-} import Foreign.C.Types foreign import ccall unsafe "foo.h somedub" somedub :: CDouble 17:33 ~ % ~/src/jhc/jhc RubyMap.hs jhc RubyMap.hs jhc 0.6.2 (-n krasyupheasy-5 ) Finding Dependencies... Using Ho Cache: '/Users/mwotton/.jhc/cache' Loading libraries: ["base","haskell98"] Library: base-1.0 </usr/local/share/jhc-0.6/base-1.0.hl> Library: haskell98-1.0 </usr/local/share/jhc-0.6/haskell98-1.0.hl> RubyMap.hs:1 - Warning: The pragma 'LANGUAGE' is unknown Main [RubyMap.hs] Typechecking...

[1 of 1] Main user error (lookupExtTypeInfo: (ELit (Foreign.C.Types.CDouble::ESort *),ELit (Foreign.C.Types.CDouble::ESort *))) if this is spamming, please let me know and i'll stop, but I'd really like to be able to use JHC in Hubris. mark

install log, suggestions
by Mark Wotton 14 Aug '09

14 Aug '09

some quick notes on the experience of installing on shae's bladeserver - configure doesn't check for DrIFT (also check for other libs) - jhc/src/Doc doesn't exist in a clean install, I had to install a symlink from jhc/doc - jhc won't use multiple cores to build libs? might be a misunderstanding on my part. also, I've been thinking about a continuous integration server, both for JHC and for other projects. Shae's volunteered his machine, and I'm happy to set up a continuous integration environment, but I wanted to make sure that I wasn't duplicating work - have you got one already? Cheers Mark

dynamic library support?
by Mark Wotton 13 Aug '09

13 Aug '09

Is there a way to build dynamic libraries in jhc such they're linkable and callable from a C driver? I'm hoping to write a bridge between ruby and haskell, and GHC's dynamic lib support seems a bit sketchy currently. Cheers Mark

How to compile new libraries from Hackage?
by Mark Wotton 12 Aug '09

12 Aug '09

so I'm feeling a bit lost and lonely outside the comforting embrace of cabal-install. I've read some of the discussions on this list, and I understand that it's not very practical to try to support Cabal as is, but what's the alternative method to compile libraries from Hackage? Where do the libraries go so jhc can find them? Is there a convention of some kind? cheers Mark

bug with Integer?
by Mark Wotton 11 Aug '09

11 Aug '09

Does JHC support unbounded integers? I get different results from main = putStrLn $ show (2 * 7540113804746346428 * 2) in GHC and JHC... Cheers Mark
