#624: "cabal haddock" should not break my build ----------------------------+----------------------------------------------- Reporter: AntoineLatter | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- See GHC bug 3799: http://hackage.haskell.org/trac/ghc/ticket/3799 With the package "syb-with-class" executing "cabal haddock" regenerates the .hi files and most of the .o files. It doesn't, however regenerate HSsyb-with-class.6.1.0.o. Since syb-with-class exports top-level declarations generated by template haskell, they have a different name every time we compile. So my (regenerated) .hi files exports names not in my .o file. If this happens during a "cabal install" we package up haddock's .hi files with the previously built HSsyb-with-class.6.1.0.o. I'm not sure if this is a Cabal bug or a haddock bug (or a GHC bug?). Either way I thought I'd post it here so people are aware of it. The work around is to turn off the auto-haddock option. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/624 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
