I got this error too. In my case it helped to install llvm-3.0 next to llvm (in ubuntu the executables are than called llc-3.0 and opt-3.0). I believe this error just came in the first phase, and was caused by the preinstalled ghc-7.4.2. But I am not sure. On 01/19/2013 07:45 AM, Stephen Paul Weber wrote:

Was that an registerised or unregisterised build? Did anyone succesfully build ghc on an arm system which produces non crashing executables?
Just finally got a BB10 device set up so I can test my cross-compiler on the ARM
I'm about to try a configuration with --enable-unregisterised to see if that helps.
I think I can configure it to use unregistered LLVM, so I'm off to try that, but this seems like a bug.
Trying that gives me:
[ 1 of 68] Compiling Distribution.Compat.Exception ( libraries/Cabal/Cabal/Distribution/Compat/Exception.hs, bootstrapping/Distribution/Compat/Exception.o ) Warning: Couldn't figure out LLVM version! Make sure you have installed LLVM ghc: could not execute: opt-3.0 make[1]: *** [utils/ghc-cabal/dist/build/tmp/ghc-cabal] Error 1 make: *** [all] Error 2
I'm using LLVM 3.1. This errors makes no sense to me, because when I just use "quick" and not unregistered, it falls back to LLVM and works fine, but now I've selected "quick-llvm" and unregistered and it can't find it?
