#12479: build fail of commercialhaskell.com with stack build on mac os x sierra beta 4 -------------------------------------+------------------------------------- Reporter: stephenb | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.0.2 Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: MacOS X | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: #12198 | Differential Rev(s): Phab:D2532 Wiki Page: | -------------------------------------+------------------------------------- Comment (by carter): Just to be clear, the ghc work flows that are impacted are those which need the system linker. Namely any dynamic linked executables , ghci , or TH. I agree with Gershom's assessment that 8.0.2 should wait till this is validated as being fixed for 10.12 and at least doesn't trigger any regressions on 10.11 and 10.10. @ilovezfs will you be able to help us consistently test that version range for correctness and absence of regressions? I could probably help with some guidance. I guess this is the first time Mac OS X support range has come up since the cpp / clang challenges in recent years. Or the more recent issue of some object code tool from llvm, nm, not defaulting to posix format for certain outputs. I would propose that we treat at least the 2-3 most recent OS X releases as "core tier 1" of our tier 1 Apple support. At least as an informal guide post? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12479#comment:31 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
