I'd certainly recommend picking up the experimental/foundation branch as Rob recommends. Its where we've been doing some additional work to get properly built into the Swift toolchain and to open up some internal APIs needed by Foundation.
Whilst I've been building Dispatch either independently or as part of a full toolchain using the buildbot_linux preset (with dispatch and install-dispatch added), I've just checked your build line and its working fine for me. It might be worth cleaning out any partial build you might have of libdispatch in your build directory, and running 'make distclean' from your libdispatch source directory. FYI, we've got some further changes to the experimental/foundation branch of libdispatch with should land in the next couple of days. This fixes some issues with the Swift overlay, and resolves a crash that we've found in the underlying libkqueue implementation.

I'm working on https://bugs.swift.org/browse/SR-710, which involves porting SourceKit to Linux. SourceKit contains a handful of references to libdispatch symbols. I have two questions: 1. Could someone share a set of instructions to build swift-corelibs-libdispatch on Linux? I'm using Ubuntu 15.10 and have installed [the dependencies listed here]( https://lists.swift.org/pipermail/swift-corelibs-dev/Week-of-Mon-20151207/000122.html ). I have tried using both `swift/utils/build-script --libdispatch` as well as the instructions in the swift-corelibs-libdispatch `INSTALL` file. Both fail with the [same errors]( https://gist.github.com/modocache/8389d5d64e39ca5a4281500f84e9ce11). Any tips? 2. I don't know much about C++, but from what I understand the C++ stdlib provides tools for asynchronous programming. I list SourceKit's uses of libdispatch in a comment on https://bugs.swift.org/browse/SR-1639. For those familiar with both C++ and libdispatch: do you think it's a good idea to migrate to C++, at least for now? Any advice would be appreciated.
