#39: language-c-0.4.2.0 compatibility --------------------+------------------------------------------------------- Reporter: guest | Type: defect Status: new | Priority: normal Milestone: | Component: general Version: 0.16.2 | Keywords: --------------------+------------------------------------------------------- Hi, for Debian, I patched c2hs to build against the language-c in the latest version. The patch is purely type-driven, and not checked against possible changes in the semantics of language-c. Thanks, Joachim -- Ticket URL: <http://hackage.haskell.org/trac/c2hs/ticket/39> c2hs <http://www.cse.unsw.edu.au/~chak/haskell/c2hs/> C->Haskell, An Interface Generator for Haskell

Great thanks. BTW, it should not matter whether you uses 'fun' or 'call' hooks. What is important is that the C header file declare the calling convention using GNU C attribute syntax. Duncan

By the way, do let us know if the current version actually works now for your use case. Duncan

My intention was to point you to the darcs repo. If that's a major problem then say so. I don't think there's anything in particular holding back a release. Duncan
