#191: Hackage should check for common QA problems in ghc-options --------------------------+------------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.1 Platform: Linux | --------------------------+------------------------------------------------- Simple test that many packages have is dodgy ghc-options, or options that would be suitable for development but not release. It should be easy to check for these. Suggestions: {{{ghc-options: -Wall -Werror}}} is a very bad combination. It means the package will break silently as soon as the next version of ghc adds a new warning, which generally does happen every major release. {{{ghc-options: -fasm}}} is unnecessary and breaks on all arches except for x86, x86-64 and ppc. {{{ghc-options: -O}}} is unnecessary since Cabal does that itself and it prevents people from configuring with the {{{--disable-optimization}}} flag. {{{ghc-options: -O2}}} may be necessary in some circumstances but people should not use it routinely for the same reasons as -O and since -O2 take a lot longer to compile most of the time and usually with little benefit. {{{ghc-options: -ffi}}} or {{{-fffi}}} use extensions: ForeignFunctionInterface. Once #190 is implemented then {{{ghc-options: -fvia-C}}} will be unnecessary too. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/191 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
