We are pleased to announce the first release candidate for GHC 7.8.1: http://www.haskell.org/ghc/dist/7.8.1-rc1/ http://www.haskell.org/ghc/docs/7.8.1-rc1/html/ This includes the source tarball and bindists for Windows, Linux, OS X, FreeBSD, and Solaris, on x86 and x86_64. There is a signed copy of the SHA256 hashes available (attached) using my GPG key (keyid 0x3B58D86F). We plan to make the 7.8.1 RC2 release quite soon, as we're aware of some existing issues. Please test as much as possible; bugs are much cheaper if we find them before the release! -- Regards, Austin Seipp, Haskell Consultant Well-Typed LLP, http://www.well-typed.com/

wrt existing issues, is there a list of these so we can avoid reporting them? Thanks George On Mon, Feb 3, 2014 at 6:35 PM, Austin Seipp wrote:

Just to note a problem I encountered on Windows, which may well be user error. I unpacked the mingw tarball and added the bin directory from it to my path. cabal install then failed with "cabal.exe: does not exist" after producing some other output. Running with -v3 suggested that the actual problem was that the ld on my path couldn't read the .o files produced by GHC. I changed my path to also include the mingw\bin directory from the tarball, and then all was fine. On 03/02/2014 22:35, Austin Seipp wrote:

Please note that GHC 7.8.1RC1 is also available for Travis-CI as part of the multiple-ghc-versions repository[1]. So you can start continuously testing your Haskell projects hosted at GitHub with GHC 7.8.1RC1 with little effort. Greetings, hvr [1]: https://github.com/hvr/multi-ghc-travis

Do you mean: $ cabal install alex --disable-tests no, but tried now and the result is still the same: cabal: Error: some packages failed to install: QuickCheck-2.6 failed during the building phase.

You can avoid this by installing QuickCheck without template haskell parts: $ cabal install -f -templateHaskell QuickCheck (syntax could be off). Regards, Arie

Hi Christian, the bindist is compiled on Solaris 11.0 so probably of no use for you on Solaris 10. Also I needed to provide separate tarball of compiled and installed libgmp.so as the Solaris 11's provided does not satisfy GHC requirements and GHC refuses to use that...

New subject: [Solaris bindist] Re: ANNOUNCE: GHC 7.8.1 Release Candidate 1

Hi Karel, Ok, yet I suppose that the #!/bin/sh script in ghc-pwd-bindist will still fail for me on Solaris 10, even if I build ghc from sources. Why was this script changed? (Or was it not?) Is still a (non-trivial) haskell binary needed to compute the current directory for ./configure? Alternatively, if one does not want to make "export LD_LIBRARY_PATH ..." Bourne shell compatible, one should start the script with: #!/bin/bash or (as I've seen elsewhere) better (?) #!/usr/bin/env bash Cheers Christian Am 05.02.2014 23:43, schrieb Karel Gardas:

Hi Christian,

the bindist is compiled on Solaris 11.0 so probably of no use for you on Solaris 10. Also I needed to provide separate tarball of compiled and installed libgmp.so as the Solaris 11's provided does not satisfy GHC requirements and GHC refuses to use that...

Hi Christian, honestly speaking I've not touched ghc-pwd-bindist script at all. Everything I did was Austin's recommended: get the source in appropriate way, make, make binary-dist. It produced tarball and I've uploaded it. Generally speaking if you are not satisfied with support for Solaris 10, please change it as you like and submit your patch to ghc-devs@haskell.org, people there are very friendly to merge if they see patch is all right... Thanks! Karel On 02/ 6/14 10:33 AM, Christian Maeder wrote:

In fact ./configure detects "/bin/bash" as SHELL under Solaris, so this setting could be used (instead of hard coding "bin/sh")! (Under FreeBSD a proper other SHELL might be found by ./configure.) Many configure files of libraries also set SHELL this way. Yet, for this ghc-pwd-bindist script it is easier to make the script (Bourne) /bin/sh compatible. Yet, I have not found out, how this script is created! utils/ghc-pwd/ghc.mk contains "utils/ghc-pwd_dist-install_WANT_BINDIST_WRAPPER = YES" but then I'm lost what build-prog does from rules/build-prog.mk. Maybe somehow the code in libraries/Cabal/Cabal/Distribution/Simple/Program/Script.hs is called, then the second line should be changed from: setEnv (var, Nothing) = ["unset " ++ var, "export " ++ var] setEnv (var, Just val) = ["export " ++ var ++ "=" ++ quote val] to: setEnv (var, Nothing) = ["unset " ++ var, "export " ++ var] setEnv (var, Just val) = [var ++ "=" ++ quote val, "export " ++ var] I guess that is still POSIX compliant.

With "TypeableN " I mean, Typeable1, Typeable2, etc. Typeable2 was not supported (below) by ghc-7.8-rc1. Where is the "backward compat"? In fact, Typeable and Typeable2 mean the same thing for ghc-7.8-rc1 and ghc-7.6 resp.! C. Am 20.02.2014 17:00, schrieb Simon Peyton Jones:

Not really: ghc-7.8 does still support TypeableN I think (for backward compat reasons). So it can't take it to mean two different things.

I think you need to import Data.OldTypeable to get Typeable2 and friends.
