I ended up uninstalling 6.12 and reinstalling haskell platform. Uninstall is easy, there is an uninstaller script in /Library/Frameworks/GHC.framework/Tools.

I'm still using Leopard, but would like to move to Snow Leopard once I get a few things out of the way. But I see that there are (or were) some tricks in getting ghc to work on OS X 10.6, apparently. These seem to be well documented, but, I'd rather spend the time on my own projects.

Is it recommended to periodically upgrade packages that came with the platform (cabal upgrade), or is it recommended that they be left alone to avoid dependency incompatibilities. Similar question for ghc itself -- can/should it be upgraded in the context of haskell platform? (I was hoping to try Leksah, but it dies without ghc 6.12.1. I seem to have 6.10.4.)

Apologies in advance if this is all documented somewhere, but I couldn't find it on the haskell platform site/trac. BTW, I'm on Mac/Leopard -- love the fact that it didn't take hours to build everything!

Is anyone else still on Leopard who can test this? I am worried that the binaries (which were linked on Snow Leopard) are not working on Leopard.

I'm still on 10.5.8. I don't have cabal-install installed yet, but I just installed GHC-6.12.1/HP-2010.1.0.0. I can verify that ghci works fine so far. I'll check out cabal-install in the next couple days. -- Live well, ~wren

BTW, I started to try the macports method (thinking that maybe building on my machine would resolve the linker problem), but the package up there seems to be the old one: $ port info haskell-platform haskell-platform @2009.2.0.2 (devel, haskell) Description: This is the the Haskell Platform: a single, standard Haskell distribution for every system. The Haskell Platform is a blessed library and tool suite for Haskell distilled from Hackage. Homepage: http://hackage.haskell.org/platform/ Runtime Dependencies: ghc, hs-platform-cgi, hs-platform-fgl, hs- platform-editline, hs-platform-GLUT, hs-platform-haskell-src, hs- platform-html, hs-platform-HUnit, hs-platform-mtl, hs-platform-network, hs-platform-OpenGL, hs-platform-parallel, hs- platform-parsec, hs-platform-QuickCheck, hs-platform-regex-base, hs- platform-regex-compat, hs-platform-regex-posix, hs-platform-stm, hs-platform-time, hs-platform-xhtml, hs- platform-zlib, hs-platform-HTTP, hs-platform-alex, hs-platform-happy, hs-platform-cabal Platforms: darwin License: unknown Maintainers: gwright@macports.org Maybe the dependencies haven't changed? Also, not a big deal, but the instructions for the dmg version here http://hackage.haskell.org/platform/new/mac.html page say to follow the instructions, but there aren't any packaged with it. I mistakenly ran the "Haskell Platform 2010.1.0.0" installer first thinking that maybe it would install ghc as a dependency, but this crashed. Then I uninstalled everything, installed GHC-6.12.1- i386.pkg, then "Haskell Platform 2010.1.0.0", and rebooted... and then experienced the cabal problem. BTW, there's some description of linker flags here: http://discussions.apple.com/thread.jspa?threadID=2151112 but the developer claims 10.5.8 solved his problems (that's what I'm on).

If there is an issue here it'd be with the binaries that ship with the platform, not GHC; can you check /usr/local/bin/cabal to see if yours has the same issue?

I'm betting I probably have to re-link the binaries with some magic "don't break on Leopard" linker flag.

It should; there's an installation script that's *supposed* to put a symlink into /usr/local/bin/cabal from /Library/Frameworks/HaskellPlatform.framework/bin/. Binaries should be there regardless. G -- Gregory Collins

I had the same problem -- downloaded and installed the new Haskell Platform, and when I tried cabal I got the: dyld .... error. I'm also on OS X 10.5.8. Also, ghc users guide appears to be missing. I filed a bug report. To solve the cabal problem I got cabal-install version 0.9.0 using version 1.9.0 of the Cabal library from darcs, and put symlink to ~/.cabal/bin/cabal for /usr/local/bin/cabal Now I'm happy (so far) with ghc 6.12.1 and platform 2010.1.0.0 Best, John V.

Duncan, is this a known issue?

It's a known issue, and it's mine. If you (naively) just expect to link on Snow Leopard without passing any special backwards-compatibility flags, and have things work on Leopard, well, Apple has news for you. G -- Gregory Collins

gcc -mmacox-version-min=10.5.8 ?

Something like that, on both gcc and ld; I think you also need a "-isysroot /blah.sdk" GCC option (unless that's only for Cocoa-specific stuff, I'm not sure). I've been dreading it but I think I'm going to have to dig out my Leopard CD and run it in a VM. G -- Gregory Collins

You won't; the point is that the default options changed incompatibly in Snow Leopard. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
