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

[Rob Allen]

Hi,

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.

Regards,

Rob....

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 <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 <https://gist.github.com/modocache/8389d5d64e39ca5a4281500f84e9ce11>). Any tips?

I list SourceKit's uses of libdispatch in a comment on https://bugs.swift.org/browse/SR-1639 <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?
