Clang 3.9.0


(Ryan Lovelett) #1

Is it known/expected that Swift will not build with Clang 3.9.0? My
personal build-bot recently updated its upstream dependency from Clang
3.8.1 to Clang 3.9.0 and since then it will not build the
swift-3.0.1-RELEASE. It seems that others have noticed this
(https://gist.github.com/eyeplum/94627aac7b4fa609108fd24b960a8805) but I
don't know if it has been reported or not.

The actual build error looks like this:

swift: /build/swiftc/src/llvm/include/llvm/Support/Casting.h:95: static

I've tried updating the ternary operator into an if/else and that works.
Well that is until it hits the next ternary.

Yes. LLVM and Clang's interfaces are not stable. You must build Swift against the 'stable' branch of the 'swift-llvm' and 'swift-clang' forks.

I've tried updating the ternary operator into an if/else and that works.
Well that is until it hits the next ternary.

You’re hitting issues in the Swift source that were exposed by the new clang and have since been fixed on master but are not fixed in the sources that are tagged swift-3.0.1-RELEASE.

Is there a reason you need to build from swift-3.0.1-RELEASE?

I think (but am not certain) these fixes are in swift-3.1-branch. Most if not all of the fixes mention problems with ArrayRef or problems building with a newer clang in the commit message. Unfortunately I don’t have a list of all the commits handy.
