#642: [ghc-6.12] support dynamic linking of executables ----------------------------+----------------------------------------------- Reporter: juhp | Owner: Type: defect | Status: new Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: Linux | ----------------------------+----------------------------------------------- Currently Cabal does not support dynamical linking of executables against Haskell shared libraries. A workaround is to configure without profiling and pass "--ghc-option=-dynamic" to cabal configure. Configuring with -dynamic and -p links to cabal builds failing with not being able to find p_dyn libraries. [It would be nice if 1.8 could be added to the "Version" selector and 6.12.1 to the "GHC Version" list here in trac.] -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/642> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #640: Cabal should warn about haskell98 dependencies

#640: Cabal should warn about haskell98 dependencies ------------------------------+--------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: low | Milestone: Component: Cabal library | Version: HEAD Severity: minor | Keywords: check, warn, haskell98 Difficulty: easy (<4 hours) | Ghcversion: Platform: | ------------------------------+--------------------------------------------- I grepped through my collection of repos, and found dozens upon dozens of uses of the 'haskell98' package (for the full list, see http://community.haskell.org/~gwern/wiki/TODO.page & scroll down). Now, either a package uses the haskell98 module names or it doesn't use them. If the package doesn't actually use any of the old module names, then clearly that's bad and it should be removed and the developer should be warned about this unconditionally. If the package does use the old module names, this is bad too: most every Haskeller got started after the hierarchical modules were made official and general, and the old module names are akin to n+k patterns - they are things that should be removed, because modules using the hierarchical module names are more comprehensible to Haskellers than the old haskell98 modules, which mingle things that have been separated (Foreign comes to mind). So use of haskell98 ought to be warned about here as well. Given that both common situations are bad and ought to be warned about, I think Cabal check ought to emit a warning whenever haskell98 is used. There *may* be some compiler or bootstrapping-related cases where haskell98 is genuinely useful, but I'm doubtful any such exist, and such would be far in the minority anyway. -- gwern -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/640> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#634: cabal-install does not recognise internal capability from Cabal 1.8 ---------------------------------+------------------------------------------ Reporter: kowey | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ If I understand correctly, Cabal 1.8 introduced a feature that lets our executable depend on a library from the same package (is this #89?). We would very much like to use this for Darcs as this would speed up our build times dramatically, but it seems that the cabal-install tool does not know how to deal with this it yet. This means we can do "runghc Setup configure" but not "cabal configure" Here is the patch that uses this for darcs: http://bugs.darcs.net/patch147 PS. I think this tracker may need to be updated with new versions (currently stops at 1.6) -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/634> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
