Re: build fail with latest 8.1 sources

I just pulled again and picked up a more recent patch by Ben Gamari: https://github.com/ghc/ghc/commit/ca1b986074757efff755c33c7f9a62c7eae43c7f This seems to have fixed the problem. The commit says 8 hours ago but for some reason I didn't pick it up 2 or 3 hours ago when I last pulled. John On Sat, Nov 12, 2016 at 3:19 PM, John Leo wrote:

That's exactly what I did--in fact clone a fresh GHC and try again, but no luck. I attached the full logs in my second message, which have the details--let me know if the attachment is not readable. Thanks very much for your help.

I’ve seen a very recent commit that mentioned bumping a TH bound. Maybe pull, make clean and try again?

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.
