#9378: Make unknown LANGUAGE pragmas a warning, not an error -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by hvr): Fyi, when you inform Cabal about the used language pragmas via `other- extensions` (which then still need to be declared on a per-module basis via pragmas), Cabal will refuse to build the project if your compiler doesn't provide all those extensions. Moreover, there is tooling to generate the `other-extensions` list automatically from the `.hs` files making up a build-target. So I'm a bit sceptical changing the semantics of `LANGUAGE` to be a mere warning would interact badly with the Cabal tooling. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9378#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
