Why is --gen-script creating failing scripts?

I've been using the recent cabal from ghc-6.7.20070814 register.sh [...] haddock-html: /pr/store/5wivrfz8pmc7hpwqgxgz44i4ihf1ka09-ghc67_filepath-1.0/nix-support/share/filepath-1.0/doc/html/filepath' | /pr/store/khvbwb3whj1c15pg7jrh7w4v2vndr8i7-ghc-6.7.20070814/bin/ghc-pkg update dist/installed-pkg-config - marc@localhost /tmp/nix-10368-0/filepath-1.0 $ ghc-pkg list /pr/store/khvbwb3whj1c15pg7jrh7w4v2vndr8i7-ghc-6.7.20070814/lib/ghc-6.7.20070814/package.conf: Cabal-1.1.7, [...] Please use either echo and add - or pass the pkg-conf dist/installed-pkg-config .. or did I mess something up? If you like I can start debugging the issue and read the source.. But propably you know what has been changed ? Marc

D.Program depends on D.Simple.Utils
by Clemens Fruhwirth 23 Aug '07

23 Aug '07

Hi, I was about to extend Dist.Simple.Utils with a method called mkSharedLibName, which depends on Compiler information, hence Dist.Simple.Utils was about to import Dist.Compiler. I ran into this dependency loop: Module imports form a cycle for modules: Cabal-1.1.7:Distribution.Compiler imports: <..> Distribution.Program <...> Cabal-1.1.7:Distribution.Program imports: <..> Distribution.Simple.Utils <..> Cabal-1.1.7:Distribution.Simple.Utils imports: <..> Distribution.Compiler <..> make: *** [.depend] Error 1 After a short discussion on #ghc, Esa Ilari Vuokko explained that Dist.* is not supposed to depend on Dist.Simple.*, so it seems reasonable to break the dependency cycle at "Program -> Simple.Utils". Program imports 'die' and two program execution helpers 'rawSystemExit' and 'rawSystemStdout' from Simple.Utils. Two dependencies on 'die' could be removed easily, hunk ./Distribution/Program.hs 192 - Nothing -> die ("Cannot find " ++ prog ++ " on the path") $ + Nothing -> return EmptyLocation hunk ./Distribution/Program.hs 213 - _ -> die ("cannot determine version of " ++ name ++ " :\n" ++ show str) + _ -> return prog { programVersion = Nothing } but the other two uses seems rather ok to me (is it ok to _|_ when an API is used in an illegal way?), namely: rawSystemProgram _ prog@(Program { programLocation = EmptyLocation }) _ = die ("Error: Could not find location for program: " ++ programName prog) Esa suggested a wider refactoring, namely to remove rawSystemExit and rawSystemStdout from Program.hs. Esa, you could explain the details? Would it be ok to move 'die' and the rawSystem helpers into the Dist.* hierarchy if this takes longer to resolve? -- Fruhwirth Clemens - http://clemens.endorphin.org

#7: add --ghc-args and such to configure ----------------------------------+----------------------------------------- Reporter: ijones | Owner: ijones Type: enhancement | Status: reopened Priority: high | Milestone: Cabal-1.2 Component: Cabal | Version: 1.1.3 Severity: normal | Resolution: Keywords: | Ghcversion: 6.2.1 Difficulty: very easy (<1 hour) | Platform: Linux ----------------------------------+----------------------------------------- Changes (by ross(a)soi.city.ac.uk) * resolution: fixed => * status: closed => reopened Comment: Done in the code, but not documented in the User's Guide. A design issue: there is a difference in naming and semantics from --configure-option (and ghc-option elsewhere). The latter takes only one option, so multiple options must each be wrapped individually. That can be a bit more cumbersome, but it avoids issues with embedded spaces. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/7> Hackage <http://example.com/> My example project
