Hello there, 2016-02-07 19:13 GMT+01:00 Ben Gamari :

The GHC Team is very pleased to announce the second release candidate of the Glasgow Haskell Compiler 8.0.1 release.

For the FreeBSD users, the vanilla binary distributions are available here, along with a brief installation guide: http://haskell.inf.elte.hu/ghc/8.0.0.20160204/ Cheers, Gábor

Hello everyone,

* Compatibility with earlier Cabal versions should be a bit more robust.

Unfortunately this characterization was perhaps a bit optimistic. Sadly the errors provided by GHC when used with an older Cabal aren't any better in -rc2 than they were in -rc1. I've opened #11558 to track this issue. Users seeing unexpected missing interface file errors need to update Cabal and cabal-install from git. This must be done using GHC 7.10 at the moment as some of Cabal's build dependencies lack a build plan with 8.0. $ git clone git://github.com/haskell/cabal $ cd cabal $ cabal update $ cabal install Cabal/ cabal-install/ Cheers, - Ben

https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=arm64&ver=8.0.0.20160204-1&stamp=1454952602 I didn’t quite follow the Cabal issues on the tickets list, so this might be known, but it certainly should not happen. Or is this a problem with 8.0.1-rc1 and I should just avoid that version somehow, and it will bootstrap with 8.0.1-rc2 just fine? Greetings, Joachim -- Joachim “nomeata” Breitner mail@joachim-breitner.de • http://www.joachim-breitner.de/ Jabber: nomeata@joachim-breitner.de • GPG-Key: 0xF0FBF51F Debian Developer: nomeata@debian.org

I'm a little bit late to the 8.0.1 show, but nevertheless: Motivated by the current discussion about -Wcompat and friends I decided to take a detailed look at the warnings in my projects and hit a regression(?): Somehow I'm unable to suppress the "Top-level binding with no type signature" warnings from 8.0.1 onwards. The gory details: In my .cabal file I set -Wall ( https://github.com/haskell-opengl/OpenGLRaw/blob/master/OpenGLRaw.cabal#L618), and in my .travis.yml I set -Werror ( https://github.com/haskell-opengl/OpenGLRaw/blob/master/.travis.yml#L76). But the -Wno-missing-signatures pragma ( https://github.com/haskell-opengl/OpenGLRaw/blob/master/src/Graphics/GL/Toke...) doesn't work, see https://travis-ci.org/haskell-opengl/OpenGLRaw/jobs/109400373. Using -fno-warn-missing-signatures didn't work, either, see https://travis-ci.org/haskell-opengl/OpenGLRaw/jobs/109396738. Am I doing something wrong here or is this really a regression? I'm quite sure that suppressions via pragmas worked in the past... :-( Cheers, S.

Thank you for RC2. I finally built ghc-8.0.0 for Fedora Rawhide (quick build): https://copr.fedorainfracloud.org/coprs/petersen/ghc-8.0.1 (perf build is still ongoing). One minor thing I noticed is that docdir seems have changed RC2 to be versioned. ie the LICENSE files for the included libraries now get installed under "/usr/share/doc/ghc-<version>/html/libraries/*/" rather than "/usr/share/doc/ghc/html/libraries/*/" before. I managed to work around that by configuring with --docdir=/usr/share/doc but it took me by surprise. I should open a ticket I guess... Jens
