Hey all. The GHC 6.10 RCs are out, and we're preparing the release of GHC proper. To help manage the transistion to GHC 6.10 it is now possible to actually build all the 3rd party Haskell packages, and publish their results wrt. the release candidate. For the first time ever, we're able to have all the 3rd party code tested and ready to go *prior* to the release of the new compiler and base libraries. Using GHC 6.10 RC from today, Cabal 1.6 and cabal-install 1.16, of 682 libraries and apps tried in total, 1 UnpackFailed 2 DownloadFailed 2 InstallFailed 16 ConfigureFailed 68 DependencyFailed 122 BuildFailed 469 InstallOk Since yesterday, * dependency failures have reduced by 5 * build failures have reduced by 10 * total successfully installed packages are **up by 14** These new packages now all build ok with the GHC 6.10 release candidate, Graphalyze-0.4 alsa-midi calc glome-hs harpy heap hmp3 ircbouncer mohws panda pandoc roguestar-engine type-level typeof unicode-prelude urlcheck Good work everyone! Some packages are still not ready though, if you maintain one of the following packages, and are able to fix it before GHC 6.10 is released, your users will be happy. The most common issues for these differences are, * Changes to Arrow class definition * Changes to types of Map and Set functions * Cabal changes * Changes to ghc-api * Changes to when 'forall' is parsed (add Rank2Types) * GHC.Prim was moved, * Changes to -fvia-C and headers * GADT changes, * pragma warnings tightened * Integer constructors have moved * New warnings and used -Werror The following packages are still producing different results than with ghc 6.8.2. Package maintainers are invited to look at them. I've marked the easy ones.

Pragma parsing Build reports for everything, produced today, are here, http://galois.com/~dons/tmp/build-logs-2008-10-13/ How to address these, as library maintainers, is addressed here, http://haskell.org/haskellwiki/Upgrading_packages If you'd like to try your own build of all of hackage, grab a package list (such as this one), http://www.galois.com/~dons/tmp/pkgs-6.10 Install a GHC 6.10 release candidate, upgrade to Cabal 1.6 (on hackage), and cabal-install 0.6 (on hackage), and then simply, cabal install -v -O0 $(cat pkgs-6.10) --build-reports This will construct a clever plan to install all the packages in the right order, and write logs to ~/.cabal/logs and a full structured build report into ~/.cabal/packages/hackage.*/build-report.log I'll start mailing maintainers personally tomorrow. -- Don
