#376: Allow constraint on using installed package versions ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Resolution: Keywords: | Difficulty: normal Ghcversion: 6.8.3 | Platform: ---------------------------------+------------------------------------------ Comment (by Peaker): The wxcore package currently has a bug that prohibits it from being installed user-locally. This forced me to install it system-wide. However, this means that it is built with only system-wide packages available as dependencies. When I want to install another package that depends on wxcore that is not system-wide, it thinks it should rebuild wxcore to make use of the better dependencies, and fails. In order to avoid this problem, I had to manually purge wxcore from cabal's cache/listing. It would be nice if I could ask cabal to use an already installed package rather than replace it, somehow. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/376#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
