Anyone have GHC 7.8.3 working on OSX Yosemite?

[Tim Watson]

Since upgrading nothing seems to work for me, everything from build to runtime seems to be segfaulting and I'm proving a total pita trying to get things re-installed. Maybe my brew/gcc toolchain needs to be rebuilt? Anyone else done this upgrade and had problems?

Hi Carter,

Sorry yeah, considering I'm a seasoned question answering person, that was a terrible ask!

ghcformacosx.github.io fails for me:

<snip>

t4@iske:bin $ ghc

dyld: Library not loaded: @rpath/libffi.dylib

  Referenced from: /Users/t4/Library/Haskell/Versions/7.8.3-x86_64/lib/ghc-7.8.3/bin/ghc

  Reason: Incompatible library version: ghc requires version 7.0.0 or later, but libffi.dylib provides version 1.0.0

Trace/BPT trap: 5

</snip>

However I think I've figured out what's up, various bits that were built back on mavericks (or even mountain lion!?) via homebrew are probably gorked now I've upgraded. Re-building my gcc tool chain now and will attempt to recompile 7.8.3 from source.

Cheers,

Tim

6) use it ghcformacosx.github.io

build and runtime of distributed-process and tests, of GHC, or of
unrelated Haskell programs?

Nah, my whole haskell tool chain is borked. The only ghc that's building properly is 7.4.2 but all (and I do mean all) compiled programs segfault when run. The other two ghc installs aren't working at all.

Going to rebuild from sources and I suspect since upgrading to yosemite that I need to rebuild/reinstall bunch of stuff via homebrew (like the brew supplied gcc tool chain and a bunch of library dependencies). Certainly the brew installed GCC I was using for the CPP was broken, since running that also complains about a similar dynamic loading error:

t4@iske:ghc-7.8.3 $ /opt/local/bin/gcc

dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib

  Referenced from: /opt/local/bin/gcc

  Reason: Incompatible library version: gcc requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0

Trace/BPT trap: 5

this is not the right mailing list for getting support on how your macports + ghc setup on 10.10 doesnt work. 

i'd suggest opening a ticket on GHC for OS X github repo to get some help there.

Are you sure it's brew? Brew doesn't install anything to /opt.

Also, ‘brew install ghc’ should get you going without any problems. (And you may want to nuke /opt and /usr/local partly before that)

I tend to not recommend brew based ghc because it hasn't been well maintained historically.  But if it works great.  Opt has macports usually.  Ghc for osx is what I like to recommend andthe maintainer is very responsive.
