Current procedure to install Hakyll (with deps)
by Mateusz Loskot 29 Jul '12

29 Jul '12

Hi, This is my first post here, so hello everyone! I'm fairly experienced with Arch ecosystem, but I'm new to Haskell. I'm going to start some Haskell hacking for Hakyll. I have shopped around, read the ArchHaskell and Haskell Package Guidelines on Arch wiki, Hakyll docs, etc. Although, it is completely unclear to me what is the current and up to date procedure of Haskell installation. My impression is that the Haskell packages are scattered between three locations: "Haskell is well supported on Arch Linux, with GHC (...) available via the official repositories, a growing number of packages made available by the ArchHaskell group (...) available in the AUR." later in the wiki states: "The [haskell] repository is the official repository of packages maintained by the ArchHaskell team." There also is "Guidelines" section which explains how to cook own Arch packages from cabal, so I'd assume it is fourth option. (It does not say anything about "Guidelines" section being dedicated to package developers/maintainers.) I guess, I can even omit Arch packages and use cabal only too. In AUR, number of packages I'm interested in are marked out of date. So, here comes my question: Considering I'm interested in Hakyll, could anyone recommend where should I grab all the related packages and required dependencies from?

X11 1.6

Any chance of getting haskell-x11 updated to 1.6? It's updated in the community repo, but I don't think I can mix the two. I'm trying to recompile xmobar and this requires X11 1.6. Thanks! - Stephen

How to install Leksah?
by Mateusz Loskot 29 Jun '12

29 Jun '12

Hi, I'd like to install Leksah [1] on my up-to-date Arch box. The only package I can find is the one in AUR [2] It has plenty of dependencies specified in makedepends in the PKGBUILD file. I have been warned about using AUR, to stay away of it if possible [1]. So, what is the recommended way to install Leksah?

Building the Haskell ABS tree

Do I need to make the PKGBUILD files (and their directories) for all of the packages in the repo before adding my own? Do I need to actually _build_ the packages that are not my own (in the sense of making the Arch Linux packages that pacman can use, with makeahpkg)? I certainly hope not! -- Gregory D. Weber, Ph.

Adding packages to cblrepo
by Alessandro Pezzoni 19 Jun '12

19 Jun '12

Hello list, I'm trying to add numeric-prelude [1] to the habs tree [2], with the intent of making a pull-request and providing a compiled package, as this seems to be what I should do to contribute to the [haskell] repo. When I try to make some PKGBUILDs, though, I get a dependency on "ghc=7.4.1-1", even if we switched to ghc-7.4.2-1 from [extra] and before that we had a ghc-7.4.1-6 package in [haskell]. How could I correct this? Alessandro [1] http://hackage.haskell.org/package/numeric-prelude/ [2] https://github.com/archhaskell/habs

Upgrade to 7.4.2
by Magnus Therning 19 Jun '12

19 Jun '12

I've been working on upgrading [haskell] to Ghc 7.4.2 for a few days now. So far no luck :( The build always fails on creating documentation. Yesterday I resorted to taking the source package from [extra], which is known to build fine... but still it failed on generating the docs. I now suspect this is due to the limited memory available on the machine I use to build (1.5GB). For the moment I've given up on building Ghc especially for use in [haskell]. In order to move on I'll instead make use of Ghc out of [extra]. If anyone has any objections to that, then please speak up. /M -- 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

Please be patient, update on the way.

There's been a new version of mtl kicking around on Hackage for a while now. I've tried to keep an eye on updating to it, but there's always been a few packages that would break on an update. Observant people will have noticed that the latest Haskell Platform includes it. And indeed, the last time I checked it was possible to update mtl without breakage (only cblrepo would break but that was easily fixed). I started doing the update, but in the middle of it the server where I build stopped accepting SSH connections. The situation is now that the admin will kick at sshd ASAP (during the day I'm told), at which time I'll be able to continue the update. I know, it's utterly embarrassing to be behind HP, but it'll be rectified post-haste. /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus Most software today is very much like an Egyptian pyramid with millions of bricks piled on top of each other, with no structural integrity, but just done by brute force and thousands of slaves. -- Alan Kay
