I use Opensuse 64 Bit and GHC 7.6.3. Compiling ends with http://lpaste.net/92023.
Probably because the version of haskell-src-exts released yesterday (http://www.haskell.org/pipermail/haskell-cafe/2013-August/108461.html) has breaking changes in its API. Install haskell-src-exts version 1.13 instead. I'll try to release a compatible version soon.
I was so stupid changing a running system :-(. After "cabal install cabal-install"I got buildwrapper errors and so I have decided to remove the whole haskell-platform-2013.2.0.0 installation from my Opensuse 64 Bit system. But now if I want to compile buildwrapper I get always the following message:
cabal: Could not resolve dependencies:
trying: buildwrapper-0.7.5 (user goal)
next goal: ghc (dependency of buildwrapper-0.7.5)".
What's the reason for this error?
Are you not getting more errors? Buildwrapper requires the ghc library, so run ghc-pkg list and ensure the ghc library appears in the list.
You are right. ghc was missing. Now it works.
New versions uploaded to Haskage, try again!
The following may be superfluous as I'm new to Haskell/Cabal and Eclipse.
Buildwrapper (Hackage) build is failing with TYPE_X (RealSrcLoc, etc.) not in scope errors on CentOS 6.4, GHC 7.04 (latest EPEL version).
Apparently a more current GHC version is needed due to API changes in GHC 7.2.1:
"The SrcSpan and SrcLoc types have been refactored so that the new RealSrcSpan and RealSrcLoc types are used when we have a real location, rather than an "unhelpful" location."
It would be helpful if you can suggest an alternate yum repo. I recently learned of "JustHub". It looks like a good source, but barring other factors I would prefer using yum.
There probably are options for supporting multiple platform/library versions, I may have over looked them while focusing on getting started. Any comments/suggestions would be appreciated.
Buildwrapper SHOULD build with GHC 7.0, we have conditional compilation enabled and I see the proper defines, but maybe we lost it at some stage and nobody noticed. Give the exact errors with lines and such...
About Centos, I have no idea, see that thread: http://stackoverflow.com/questions/5286493/is-it-possible-to-install-the-haskell-platform-on-centos.
I think CentOs is a very conservative platform, no?
