Hi, trying out haskell. Have osx 10.7 and ghc 7.0.4 via homebrew When attempting to compile a program via cabal i get ghc: could not execute: opt I assume I have something missing / not configured with my env. Can someone point me in the direction ? Thanks
Hi Graham,
opt is the is the LLVM optimizer, so you need to install LLVM.
Cheers,
Oliver

you can use brew install llvm to install llvm. It worked for me.

Thanks, i though the llvm was part of the OS install these days. Not that I know much about OSX coding.
Will download and try it.
Thanks

Xcode 4 includes only part of LLVM; ghc has apparently found that part and is trying to use it, but "opt" is one of the pieces that isn't there. You'll need to install a full LLVM or find out how to get ghc to not use -fllvm by default (I *think* that's what's going on?). -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
