(I noticed my reply to Mathew Mills didn't reach the GHC list, so here it is.) On Wednesday 11 October 2006 21:53, Mathew Mills wrote:
Interesting. I was unable to reproduce your problem. What platform are you running on? Are you using a binary distribution or one you built from source?
I'm running Gentoo Linux (x86). I emerged the latest GHC (6.6). So GHC is built from source. $ uname -a Linux bassbox 2.6.17-gentoo-r7 #7 PREEMPT Tue Oct 3 01:15:50 CEST 2006 i686 AMD Athlon(tm) 64 Processor 3200+ GNU/Linux $ gcc --version gcc (GCC) 4.1.1 (Gentoo 4.1.1) $ ghc --version The Glorious Glasgow Haskell Compilation System, version 6.6 $ ghc-pkg list /usr/lib/ghc-6.6/package.conf: Cabal-1.1.6, GLUT-2.0, HaXml-1.13.2, OpenGL-2.1, QuickCheck-1.0, base-2.0, (ghc-6.6), haskell-src-1.0, haskell-src-exts-0.2, haskell98-1.0, html-1.0, mtl-1.0, network-2.0, parsec-2.0, readline-1.0, regex-base-0.71, regex-compat-0.71, regex-posix-0.71, rts-1.0, stm-2.0, template-haskell-2.0, unix-1.0 BTW, why is the (ghc-6.6) package listed between parentheses? I also emerged GHC on another PC with the same architecture running the same Gentoo version and there I had the same error: $ ghci -package ghc ___ ___ _ / _ \ /\ /\/ __(_) / /_\// /_/ / / | | GHC Interactive, version 6.6, for Haskell 98. / /_\\/ __ / /___| | http://www.haskell.org/ghc/ \____/\/ /_/\____/|_| Type :? for help.

Seems like something didn't build right... You might use 'nm' to examine your libHSCabal.a to see if a similarly named symbol is present. For example, is there a leading underscore? May the version ("m1zi1zi6") isn't present?
When I 'nm /usr/lib/ghc-6.6/libHSCabal.a' and search for, for example, "Cabalzm1zi1zi6_DistributionziPackage_a_closure" I see that it is indeed an (U)ndefined symbol. I don't know what that means though. Reemerging GHC or Cabal also doesn't help. Any help is highly appreciated. Greetings, Bas van Dijk.
