#89: Sharing of object files between executable builds? ---------------------------------+------------------------------------------ Reporter: bjorn@… | Owner: blackh Type: enhancement | Status: assigned Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: Severity: normal | Keywords: Difficulty: easy (<4 hours) | Ghcversion: 6.4.2 Platform: Linux | ---------------------------------+------------------------------------------ Comment(by duncan): Replying to [comment:19 AnttiJuhaniKaijanaho]:

From what I understand, the patch above does not solve the original request: the useless rebuilding of Other-Modules shared by multiple Executables.

Right the current system does not help for packages with several executables but no library. For that we need to support convenience / private libraries as in #276. I do not plan to implement ad-hoc / implicit / opportunitsic sharing of .o files. It is too hard to implement at the moment. It requires tracking lots of information to check if the sharing is safe. It might become possible in a future build system that obsessively tracks all dependencies. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/89#comment:20 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
