Re: GHC 8.0.2 status

The easiest way I found to build stackage recently was to take the cabal.config file [1] and then manipulate it to just install each package in turn. cabal install package-1 cabal install package-2 This was quite a bit easier than using stackage-curator if you just want to build packages to check that they work [1]: https://www.stackage.org/lts-7.2/cabal.config Matt On Tue, Oct 4, 2016 at 9:38 AM, Simon Peyton Jones via ghc-devs wrote:

Smoke-testing with Stackage would be a great idea. In the past Michael Snoyman has kindly done that for us, but ultimately some automation would be good.

Hi Ben,

while in the eye of the cyclone, as we're waiting for these last few OS X issues to clear up... I was wondering, do you currently have a means to "vet" release candidates before cutting a new release?

More to the point, to check that a point release like these doesn't include any breaking changes it might be useful to try compiling all of Stackage with it, even if it's just once, much like the Stackage curators do. As you may have seen a few hours ago, e.g. singletons doesn't compile using the current GHC 8.0.2 candidate (tip of ghc-8.0 branch). It did compile just fine using 8.0.1. And FWIW it also compiles okay with GHC HEAD.

Likely this has been discussed before. So I'm just enquiring about status regarding adding this item in the workflow.

Best,

Hello everyone,

The week before ICFP I was able to get the ghc-8.0 branch ready for an 8.0.2 release, which I intended to cut this week. In the intervening time an additional rather serious issue was reported affected Mac OS X Sierra (#12479). Since this issue affects the usability of GHC on the new OS X release, we'll be deferring the 8.0.2 release until it has been resolved.

While there appears to be an actionable path forward on this ticket, we will need someone with an affected machine and an understanding of GHC's use of dynamic linking to step up to implement. Otherwise it looks like the release will be delayed at least until October 9, when darchon has time to have a look.

Sorry to be the bearer of bad news!

Cheers,
