[Hackage] #231: "buildable: False" should fail the current configuration
#231: "buildable: False" should fail the current configuration ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- Currently resolving configurations does not take account of the `buildable` field. It should act rather like `build-depends: non- existant`, though with a different error message. If possible the error message should relate to the guard condition expression (the conjunction if there are several nested guards). At the moment it is not considered at all and we don't notice that the package cannot be built until the build step, rather than the configure step. One problem is that it's not clear if `buildable: False` is always fatal. People sometimes do that for test executables that are not supposed to be installed. So what should the behaviour be? The lib or only exe failing to configure must be an error. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/231 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

The semantics would be slightly different to `buildable: False`. It would make configuring the whole package fail, not just disable building that executable or library. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/231#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
