[Insight-developers] OS X 10.7.3 breaks kwsys

[Bradley Lowekamp]

Hello,

I think I re-produced your problem trying to set up clang for SimpleITK:

http://open.cdash.org/viewBuildError.php?buildid=2112999

I just downloaded the latest XCode, and patched the system:

$ clang --version
Apple clang version 1.7 (tags/Apple/clang-77) (based on LLVM 2.9svn)
Target: x86_64-apple-darwin10
Thread model: posix

Does ITK work mostly with this version of clang? Is this the version you are using, or some mac-ports like version?

Thanks,
Brad
