independently or as part of a full toolchain using the buildbot_linux preset

'make distclean' from your libdispatch source directory.</font>

<br class=""><font size="3" class="">Hello all!</font>
<br class="">
<br class=""><font size="3" class="">I'm working on </font><a href="https://bugs.swift.org/browse/SR-710" target="_blank" class=""><font size="3" color="blue" class=""><u class="">https://bugs.swift.org/browse/SR-710</u></font></a><font size="3" class="">,
which involves porting SourceKit to Linux. SourceKit contains a handful
of references to libdispatch symbols.<br class="">
<br class="">
I have two questions:<br class="">
<br class="">
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](</font><a href="https://lists.swift.org/pipermail/swift-corelibs-dev/Week-of-Mon-20151207/000122.html" target="_blank" class=""><font size="3" color="blue" class=""><u class="">https://lists.swift.org/pipermail/swift-corelibs-dev/Week-of-Mon-20151207/000122.html</u></font></a><font size="3" class="">).
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](</font><a href="https://gist.github.com/modocache/8389d5d64e39ca5a4281500f84e9ce11" target="_blank" class=""><font size="3" color="blue" class=""><u class="">https://gist.github.com/modocache/8389d5d64e39ca5a4281500f84e9ce11</u></font></a><font size="3" class="">).
Any tips?</font>
<br class="">
<br class=""><font size="3" class="">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 </font><a href="https://bugs.swift.org/browse/SR-1639" target="_blank" class=""><font size="3" color="blue" class=""><u class="">https://bugs.swift.org/browse/SR-1639</u></font></a><font size="3" class="">.
For those familiar with both C++ and libdispatch: do you think it's a good
idea to migrate to C++, at least for now?</font>
<br class="">
<br class=""><font size="3" class="">Any advice would be appreciated. Thanks!!</font>
