ANNOUNCE: c2hs 0.15.0 "Rainy Days"
by Duncan Coutts 21 Nov '07

21 Nov '07

All, c2hs 0.15.0 code name "Rainy Days" is out and available from hackage http://hackage.haskell.org/cgi-bin/hackage-scripts/package/c2hs-0.15.0 or the c2hs website: http://www.cse.unsw.edu.au/~chak/haskell/c2hs/ http://www.cse.unsw.edu.au/~chak/haskell/c2hs/c2hs-0.15.0.tar.gz If this package turns out not to be totally broken then I'll announce it on the main Haskell mailing list. Some notable changes since 0.14.5: * New C parser that can parse all of C99 and GNU C * Lots and lots of old code removal * Make c2hs integrate better with Cabal (1.1.7 or later) * Several bug fixes and improvements from Udo: * allowing variadic functions in structures * allowing call and fun hooks for FunPtrs in C structs * embedded arrays size calculated correctly Duncan

Subject: Problem configuring c2hs with Cabal-1.2
by Judah Jacobson 14 Oct '07

14 Oct '07

I just downloaded c2hs (HEAD version) and tried to run "runhaskell Setup.hs configure" using the ghc 6.8 release candidate (i.e., Cabal 1.2), and got the following error: > Configuring c2hs-0.15.0... > Setup.hs: Error: Non-empty library, but empty exposed modules list. Cabal may not build this library correctly The .cabal file is parseable by ghc-6.6.1 (with Cabal 1.1.6.2). It's unclear to me whether this counts as a c2hs bug or a Cabal bug (maybe the above message should only be a warning?), so I'm cc'ing both lists. Also note that regardless, c2hs will need to be updated to work with base-2.0; when I tried ghc-6.8 with Cabal-1.1.6, I got the following error: > base/state/CIO.hs:71:7: > Could not find module `System.Cmd': > it is a member of package process-1.0, which is hidden Best, -Judah
