Re: [GHC] #7359: unix-2.6.0.0 fails to install on mac os x with 7.4.* (works with 7.6.1)

#7359: unix-2.6.0.0 fails to install on mac os x with 7.4.* (works with 7.6.1) -------------------------------+-------------------------------------------- Reporter: AndreasVoellmy | Owner: igloo Type: bug | Status: new Priority: highest | Milestone: 7.6.3 Component: libraries/unix | Version: 7.4.1 Keywords: unix package | Os: MacOS X Architecture: x86_64 (amd64) | Failure: Other Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | -------------------------------+-------------------------------------------- Comment(by MtnViewMark): Upon further investigation of George's situation, which I suspect is the same as others, this is version of "Cabal hell": George's system had multiple versions of packages, including some newer versions of packages that are supplied with GHC. A line from verbose cabal output tells the story: {{{ rejecting: unix-2.5.1.1/installed-296... (conflict: cairo => bytestring==0.10.0.1/installed-9b0..., unix => bytestring==0.9.2.1/installed-004...) }}} That is, cabal rejected the installed unix-2.5.1.1 because it was compiled against bytestring-0.9.2.1 (both supplied with GHC 7.4.1, and with HP 2012.4.0.0)... and the installed version of cairo it picked (0.12.4) was compiled against bytestring-0.10.0.1 (which was also installed). The only solution cabal could find was to pick unix-2.6.0.1. However, that, as we know (and expect) is incompatible with GHC-7.4.2. So the bug is that unix should have some dependency on ghc, which in turn would cause Cabal to give up in this situation - because the compiler essentially constrains the version of unix to just one. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7359#comment:11> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
