#188: file extensions --------------------------+------------------------------------------------- Reporter: guest | 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 | --------------------------+------------------------------------------------- GHC ignores Objective C sources unless -x c is passed to it on the command line before the source files. As far as I could tell there is no way to pass that option to GHC through Cabal so no .m files ever get built (well.. not completely true - setting ghc-options works but that breaks compilation of Haskell code). One way to get this to work would be to just add some extra code in Cabal to automatically pass -x c for .m files. This is probably a bad idea as someone might want or need to compile files using some other extension at some point. Another option is add some way of specifying compile options on a per-file (or group of files) basis: setting ghc-options to -x c just for one set of files. Still very limited but it's an improvement over the first option. Third option I can think of is to add a way of specifying compiler/extension pairs in Cabal so given compilers are automatically used to compile files with corresponding extensions. Depending on how much time I have I might look into adding this functionality myself but would like some feedback on which approach to take. Otherwise I might have to stick with autotools and ignore Cabal until it gets a bit more mature and flexible. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/188 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
