#12091: 'Variable not in scope" when using GHCi with `-fobject-code` -------------------------------------+------------------------------------- Reporter: thomie | Owner: Type: bug | Status: new Priority: high | Milestone: Component: GHCi | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #7253 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): I know the problem but I don't know how to fix it. `let x = ...` is compiled as a statement, `x = ...` is compiled as a declaration. Desugarer dumps unused declarations if the target is not `HscInterpreted` or `HscNothing` (see `DynFlags.targetRetainsAllBindings`), but nothing like that is done for statements. Since `-fobject-code` sets target something other than `HscInterpreted` and `HscNothing`, `x` gets dumped. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12091#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
