[swift-corelibs-dev] libdispatch on Linux, or C++ std::async?

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.

For what it's worth, I can't get the master branch to build either, but I
can get the experimental/foundation branch to build.

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](
). 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](
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. Thanks!!
