#9204: Conflicting definition in hs-boot file -------------------------------------+------------------------------------ Reporter: Feuerbach | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by Feuerbach): If I add a role annotation to the hs-boot file, this works. My guess is that since the hs-boot doesn't have the complete information about the type, it cannot infer the phantom role of the parameter. Still, I wish I didn't have to deal with this. But if this isn't possible, at least the error message should suggest adding the role annotation to the hs-boot file. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9204#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
