haskell/haskell-glade 0.12.1-1 related problems
by Peter Hercek 27 Oct '11

27 Oct '11

arch: x86_64 haskell/haskell-glade 0.12.1-1 does not seem to be rebuilt against the latest community/haskell-gtk 0.12.1-1 There was some renamin probably so conflicts appear now. My guess would be that community packages got haskell prefix instead of gtk2hs? Not really sure. Anyway the renames lead to conflicts and mixing packages from [community] and [haskell]. You probably will not have any problems if you do not use haskell-glade. I solved it by just by putting [haskell] before [community] in pacman.conf. Which probably is a good thing in general. Peter.

Broken dependencies for happstack, how can I help again?
by Fabio Riga 21 Oct '11

21 Oct '11

Hello everybody, some time ago I helped adding some package in the repo, and was just starting to understand how to do this when Peter dropped maintaining the repo in favour of Magnus. Magnus introduced this new method with cblrepo, that (it seems to me) automate the updating process, so the group didn't need my work for updating "manually" the packages. Unfortunately today pacman rejected to update my system because happstack-server now need an old version of a package already present. haskell-happstack-server: require haskell-hslogger=1.1.0 (in community there's 1.1.5) Why the requiring a fixed version, when the cabal file doesn't? Is there a way to solve the problem without modifying manually the PKGBUILD? If I do modify the PKGBUILD manually how can I make this available to the repo? I also would like to help adding some more package, but I still don't know how to do this with cblrepo. Thanks for your work, I hope this can help. Cheers Fabio

I've planned to work on adding pkgrel handling to cblrepo, but haven't gotten that far yet. Currently these cases are caught iff the person updating habs uses cblrepo properly, this isn't ideal. > AFAIK, exact pacman dependencies will detect all the problems when > installing a binary package.

Well and possibly people who want to install everything haskell > related as I mentioned below. That's a rather specialised use-case AFAIU. The ArchHaskell team only controls the [haskell] repo, so a group would only exist there. It's just as easy to install everything from a single repo using the output from `pacman -Sl haskell` then. For the use-case of installing all Haskell packages a group only be worthwhile if it existed in the official Arch repos as well. > I do not have any tool for this.

This in order to put in proper dependencies. > Anyway my call to create haskell (or ghc) group was not only for [haskell] > but also for community/extra. The Arch devs on the list will have to weigh in on this. It does seem to be a slightly out-of-the-ordinary use of a group. /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus

creation of haskell (or ghc) pacman group
by Peter Hercek 20 Oct '11

20 Oct '11

Hi, This is a call to create pacman group with name haskell (or ghc or something similar). All packages which depend on ghc would belong to the group. The reason why I would like to see this is to allow disabling update of any ghc dependency easily in pacman.conf. It would be cool if something like "IgnoreGroup = haskell" in /etc/pacman.conf would postpone update of any ghc dependency. Normally non-haskell packages do not need this but since haskell has no backward binary compatibility it can be really useful sometimes. If somebody installs everything from haskell, then this would also allow installing everything at once (using the group name). Although for this to work we might need first to make sure there are no duplicates between extra/community/haskell repositories. Not sure how trying to install whole group would behave when it hits duplicates (like e.g. gtk2hs-gtk in community and haskell-gtk2hs-gtk in haskell (well, the one in haskell is more useful since it provides glade bindings too)). Any opinions? Can we do it next time there is some big update? Peter.

mirroring arch haskell
by Piyush P Kurur 17 Oct '11

Hi, I am part of a team who run an arch linux mirror for indian sites. Does it make sense to mirror the haskell repository ? If so how do I go about setting it up. Specifically whom should I contact before starting to rsync. Regards ppk

Another update done (x86_64 only)
by Magnus Therning 08 Oct '11

08 Oct '11

I've just finished compiling the bunch of updates that were performed during my absence. 130 packages updated, and I've only had time to compile for x86_64 yet. The packages are in my private repo[1], since I still don't have proper access to the server. If some one with access would copy it over to [haskell] then I'd very much appreciate it. I'll probably get around to compiling for i686 this weekend. It would of course be very much appreciated if someone else beat me too it though ;) /M [1] [h4a]: http://www.kiwilight.com/~magnus/$repo/$arch -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus Perl is another example of filling a tiny, short-term need, and then being a real problem in the longer term. -- Alan Kay
