Hi Thomas,

Can you check that “which llc”/“which opt” point to the the LLVM 3.0 versions?

(or just run llc —version to make sure it’s 3.0)

Are you on 10.8 with Xcode 4.6?

Cheers

Luke

Hi,

I've just followed instructions for "Building a GHC cross-compiler for Apple iOS targets (1)", and I'm getting stuck during "make" while building libffi. Specifically I get errors like "no such instruction" and warnings about junk characters. 

I was able to build libffi using the build-ios.sh script found in libffi-3.0.13.tar.gz (2), but I noticed a less recent version (3.0.8) was listed in the "tarballs" file of the ghc distribution. Not sure if that makes any difference though. 

If anyone has suggestions for me, please let me know.

Thanks in advance,

Thomas
