#12518: Allow customizing immutable package dbs by stacking -------------------------------------+------------------------------------- Reporter: harendra | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Package system | 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: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by harendra): No, the issue is at a lower level than environments. With existing GHC options, it is not possible to express what is required here. We want GHC to choose packages in a way so as to stack the dbs on top of each other (upper dbs in the stack overriding the lower ones) rather than union them which is the default behavior. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12518#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
