I encountered this problem approximately a month ago building HEAD and reported it to Ian: http://www.haskell.org/pipermail/cvs-ghc/2011-November/068562.html His fix worked - but I was doing a build from source. The problem now is that this is a -build-time- option, not a runtime option, but you're using pre-built binaries: ones that were built on Linux systems using GNU ld, not gold. So removing gold is basically your only hope for the 7.4.1 RC. Alternatively, you could probably tell GHC which ld to use by aliasing GHC to something like 'ghc -pgml ld.ld' - Oneiric installs gold under 'ld.gold' and moves GNU ld to 'ld.ld' so you still have both installed. It just updates the ld symlink to point to the gold binary by default. So if 7.4.1 final wants to support gold, this logic needs to be moved to runtime somehow. This should probably be discussed on cvs-ghc or glasgow-haskell-users with Ian et al. On Tue, Dec 27, 2011 at 4:00 PM, Michael Snoyman wrote:

Hi all,

One other little GHC 7.4 note. When I first tried building code with it, I got the following error message:

/usr/bin/ld: --hash-size=31: unknown option

Once I uninstalled binutils-gold, everything went just fine. Has anyone else experienced this? I'm running Ubuntu Oneiric.

Michael
