#52582: GHC RTS incompatibility with Sierra ---------------------------+-------------------------------- Reporter: shanemikel1@… | Owner: macports-tickets@… Type: defect | Status: new Priority: High | Milestone: Component: ports | Version: 2.3.4 Keywords: | Port: ghc ---------------------------+-------------------------------- Looks like we have a problem with Sierra. GHC won't build, and it looks like a problem in the RTS that doesn't account for some symbol change in some OS time library... I don't really know what's going on here, but I've found a few things that might help: https://mail.haskell.org/pipermail/ghc-devs/2016-July/012508.html If you follow through that mailing list, you'll find what looks to me like a few proposed patches.. I've also attached my build logs. -- Ticket URL: <https://trac.macports.org/ticket/52582> MacPorts <https://www.macports.org/> Ports system for the Mac operating system
