#782: When building a plan, use installed package dependencies in preference to those from Hackage ---------------------------------+------------------------------------------ Reporter: batterseapower | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ Comment(by duncan): The dep planner does prefer installed packages to source ones, but not quite in the simple way you expect. This is a misfeature of the rather naive constraint solver algorithm that we're currently using. The solver is slated for a rewrite (to support the private dependencies feature) and hopefully this issue will be taken care of at the same time. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/782#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
