I’ve seen a very recent commit that mentioned bumping a TH bound. Maybe pull, make clean and try again?
Simon From: ghc-devs [mailto:ghc-devs-boun...@haskell.org] On Behalf Of John Leo Sent: 12 November 2016 22:48 To: ghc-devs <ghc-devs@haskell.org> Subject: build fail with latest 8.1 sources Hi everyone, I'm trying to build the latest 8.1 sources on a Mac running El Capitan. I'm getting an error I'd never seen before and wonder if anyone has any pointers of how I might fix things. I blew away my GHC, re-cloned from github, reconfigured and I still get the same error. The following are the relevant output lines; the problem is that the template-haskell version doesn't seem to match. I'm not sure whether this is coming from the template-haskell in 8.1 or in 8.0.1 (which I'm using to build 8.1), but checking the latter I have version 2.11.0.0 which I assume should be sufficient.
