#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 duncan): The root problem with wxcore is that the dependencies it ends up registering with ghc-pkg are almost unrelated to those stated in the .cabal file. So when cabal-install makes its install plan it picks deps that are different from the deps it's installed with already and so it has to rebuild it. Perhaps as a diagnostic for the custom build type, cabal should check that the registered package is actually consistent with the info in the .cabal file. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/376#comment:2 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
