[Hackage] #820: cabal-install clobbers itself on multi-arch platforms
#820: cabal-install clobbers itself on multi-arch platforms ---------------------------------+------------------------------------------ Reporter: bos | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ On my Mac, I have 32-bit and 64-bit versions of GHC 7.0.2 installed, and cabal installs the object and interface files into the same directory. The {{{$arch}}} variable looks like it should do the right thing, but in fact it's expanded to whatever architecture cabal-install was built for, not the architecture that's supported by GHC itself. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/820 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

We need to be able to specify or discover the target architecture. I see that as of ghc-7, ghc --info now reports its target platform: {{{ ,("Build platform","x86_64-unknown-linux") ,("Host platform","x86_64-unknown-linux") ,("Target platform","x86_64-unknown-linux") }}} Can you check what it uses on OSX 32 and 64 bit? -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/820#comment:2 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
