[Hackage] #890: Base library build fails with detailed build reporting
#890: Base library build fails with detailed build reporting ---------------------------------+------------------------------------------ Reporter: batterseapower | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ If you turn on detailed build reports with `--build-log=foo.log` then cabal-install uses the external setup method for a package rather than the internal setup method. If you try to use the external setup method with the "base" package then compiling the setup executable like this fails: {{{ /usr/bin/ghc -v --make ./dist/setup/setup.hs -o ./dist/setup/setup -odir ./dist/setup -hidir ./dist/setup -i -i. -package-conf /Users/mbolingbroke/Programming/Checkouts/hackage-server/hackage-build /build-cache/local.conf.d -package Cabal-1.10.2.0 }}} The reason is that the base package exports a Prelude module which is erroneously picked up when compiling Setup.hs in preference to the Prelude exported by the installed base library. This manifests as: {{{ *** Chasing dependencies: Chasing modules from: *dist/setup/setup.hs Prelude.hs:38:2: lexical error at character 'i' }}} (Because the Prelude in the base module uses CPP) -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/890 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

Is there a good reason for this to be here? You probably only want it when you are compiling the Cabal package itself. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/890#comment:2 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

And anyway compiling "base" with Cabal fails even if you fix this particular bug. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/890#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

That ought to fix the immediate problem. As you say, there's bigger issues for compiling base separately from the ghc build process. It would be nice though, e.g. for creating new sets of libs for cross-compilation. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/890#comment:4 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
