Dear all, being completely new to Haskell I wanted to explore what DPH is about, so I tried to install it via cabal install dph-examples but the installation process stops once it gets to installing the actual examples package: --- Building dph-examples-0.6.1.3... Preprocessing executable 'dph-spectral-smvm' for dph-examples-0.6.1.3... [1 of 3] Compiling Vectorised ( examples/spectral/SMVM/dph/Vectorised.hs, dist/build/dph-spectral-smvm/dph-spectral-smvm-tmp/Vectorised.o ) exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u} exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u} exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u} exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u} exprType TYPE ghc-prim:GHC.Types.Double{(w) tc 3u} exprType TYPE (ghc-prim:GHC.Types.Int{(w) tc 3J}, ghc-prim:GHC.Types.Double{(w) tc 3u}) Warning: Couldn't figure out LLVM version! Make sure you have installed LLVM ghc: could not execute: opt cabal: Error: some packages failed to install: dph-examples-0.6.1.3 failed during the building phase. The exception was: ExitFailure 1 --- This is the rest of my setup: Mac OS X 10.7.4 Xcode 4.3.3 + Command Line Tools (from within Xcode) Haskell Platform 2012.2.0.0 32bit Why doesn't Haskell find the LLVM compiler? Is there a way to install the remaining examples without LLVM compilation? Thanks, Oliver
