#89: Sharing of object files between executable builds? ---------------------------------+------------------------------------------ Reporter: bjorn@… | Owner: duncan Type: enhancement | Status: new 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 StephenBlackheath): Paul - You have to use the hs-source-dirs: option and make sure you are not building your executables in the same directory as your library, because GHC will always choose source files in the local directory in preference to libraries. It would certainly be nice to fix this, but it would need to be fixed in GHC. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/89#comment:35> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

It compiles, but A get compiled three times: once for the library, once for B and ones for C. Is that "normal" ? -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/89#comment:34> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
