A new comment on the post #274 "Arch Linux Updates to GHC 6.12" is waiting for your approval http://archhaskell.wordpress.com/2010/01/31/arch-linux-updates-to-ghc-6-12/ Author : sargon (IP: 86.103.203.159 , 159-203-103-86.dynamic.dsl.tng.de) E-mail : danielehlers(a)mindeye.net URL : Whois : http://ws.arin.net/cgi-bin/whois.pl?queryinput=86.103.203.159 Comment: It first seems to be fine that we now have 6.12, but under the fact that many of the tools and library's haven't adopted this ghc release and the big red stop on the ghc download page for 6.12 it seems unwary. Personally, I currently develop some apps which use gtk2hs and c2hs, which both didn't build with stable releases or in the case of c2hs only with some handwork, but also parts of code running fine with 6.10 didn't build with 6.12. But enough blubbering, is there any way to have 6.10 back or maybe aside from 6.12.

ANNOUNCE: GHC version 6.10.4
by Ian Lynagh 12 Oct '13

12 Oct '13

============================================================== The (Interactive) Glasgow Haskell Compiler -- version 6.10.4 ============================================================== The GHC Team is pleased to announce a new patchlevel release of GHC. This release contains a number of bugfixes relative to 6.10.3, so we recommend upgrading. Release notes are here: http://haskell.org/ghc/docs/6.10.4/html/users_guide/release-6-10-4.html How to get it ~~~~~~~~~~~~~ The easy way is to go to the web page, which should be self-explanatory: http://www.haskell.org/ghc/ We supply binary builds in the native package format for many platforms, and the source distribution is available from the same place. Packages will appear as they are built - if the package for your system isn't available yet, please try again later. Background ~~~~~~~~~~ Haskell is a standard lazy functional programming language; the current language version is Haskell 98, agreed in December 1998 and revised December 2002. GHC is a state-of-the-art programming suite for Haskell. Included is an optimising compiler generating good code for a variety of platforms, together with an interactive system for convenient, quick development. The distribution includes space and time profiling facilities, a large collection of libraries, and support for various language extensions, including concurrency, exceptions, and foreign language interfaces (C, whatever). GHC is distributed under a BSD-style open source license. A wide variety of Haskell related resources (tutorials, libraries, specifications, documentation, compilers, interpreters, references, contact information, links to research groups) are available from the Haskell home page (see below). On-line GHC-related resources ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Relevant URLs on the World-Wide Web: GHC home page http://www.haskell.org/ghc/ GHC developers' home page http://hackage.haskell.org/trac/ghc/ Haskell home page http://www.haskell.org/ Supported Platforms ~~~~~~~~~~~~~~~~~~~ The list of platforms we support, and the people responsible for them, is here: http://hackage.haskell.org/trac/ghc/wiki/Contributors Ports to other platforms are possible with varying degrees of difficulty. The Building Guide describes how to go about porting to a new platform: http://hackage.haskell.org/trac/ghc/wiki/Building Developers ~~~~~~~~~~ We welcome new contributors. Instructions on accessing our source code repository, and getting started with hacking on GHC, are available from the GHC's developer's site run by Trac: http://hackage.haskell.org/trac/ghc/ Mailing lists ~~~~~~~~~~~~~ We run mailing lists for GHC users and bug reports; to subscribe, use the web interfaces at http://www.haskell.org/mailman/listinfo/glasgow-haskell-users http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs There are several other haskell and ghc-related mailing lists on www.haskell.org; for the full list, see http://www.haskell.org/mailman/listinfo/ Some GHC developers hang out on #haskell on IRC, too: http://www.haskell.org/haskellwiki/IRC_channel Please report bugs using our bug tracking system. Instructions on reporting bugs can be found here: http://www.haskell.org/ghc/reportabug _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users(a)haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users ----- End forwarded message -----

[Haskell] haskell documentation
by Piyush P Kurur 12 Oct '13

12 Oct '13

Hi, I am a Arch linux + GHC user. I found it difficult to download documentations for GHC and all the modules. The GHC site does not seem to have a single tar.gz file by which one could down load the entire documentation tree. Same problem for modules build via yaourt. Of course one could build it directly from the appropriate cabal package but is there an automatic way via pacman/yaourt for example ?

Linker Scripts on Arch & GHC
by Александър Л. Димитров 12 Oct '13

12 Oct '13

Hello fellow Arch-Haskellers Sorry for disturbing this peaceful list, but I only recently ran into what ultimately turned out to be a problem with Arch Linux' layout of system libraries and GHC's lacking support for linker scripts. My original bug report to the yi-devel mailing list is rather longish, so I'll just link you to it and then summarize the problem: http://tinyurl.com/6qrhnk http://preview.tinyurl.com/6qrhnk The problem: terminfo links against /usr/lib/libncurses.so, which on most distros is a symlink to something that makes more sense (like /lib/libncurses.so.5) On Arch, this is a linker script instead, which GHC cannot interpret. It thus fails with a linker error: Prelude> :m +System.Console.Terminfo Prelude System.Console.Terminfo> term <- setupTerm "xterm" Loading package syb ... linking ... done. Loading package base-3.0.3.0 ... linking ... done. Loading package terminfo-0.2.2.1 ... <command line>: can't load .so/.DLL for: ncurses (/usr/lib/libncurses.so: file too short) Gwern then kindly forwarded the Mail to Don (his response is in the above thread.) The problem with the proposed solution (for now) is that it involves manually erasing /usr/lib/libncurses.so and replacing it with a symlink. This solution has obvious flaws, of course. Most importantly, it doesn't really resolve the issue. There is at least one other package on AUR which is affected: http://aur.archlinux.org/packages.php?ID=18495 Since I have no clue about linker scripts, and no clue about GHC's linking system either, I decided to forward the issue here. It's probably unlikely that Arch will move away from linker scripts (or is it?), so the solution would be implementing (some level of basic) support in GHC? Best, Aleks PS: and thanks for your current efforts, the Haskell support was the reason for me to switch from Debian to Arch :-)

Snap web framework - not in ArchHaskell?
by Dawid Loubser 09 Oct '13

09 Oct '13

Hi all, I noticed that neither the snap, nor the yesod web frameworks are in the arch-haskell repo - is there a specific reason for this? What would you recommend is the best way to install and use snap? (since it has been made clear that cabal is not a package manager, yet snap recommends installing it via cabal... :-S ) kind regards, -- Dawid Loubser <dawid.loubser(a)ibi.co.za>

OpenGLRaw dependencies
by Mike Ledger 03 Oct '13

03 Oct '13

Hi haskell-openglraw should depend on libgl, not mesa-libgl. Since it depends on mesa-libgl on systems with nvidia such as mine, it's impossible to install, because nvidia has its own libgl. Thanks, Mike
