Libdispatch build failure

Compiling on a Macbook Pro running GNU/Linux, there is a lot that does compile but the build fails as follows. Does anyone know if this is a known problem?

The source code was fetched using Slava_Pestov's recommended method:

You are missing libbsd's developer package (this is documented in README.md). The package installation is specific to your Linux distribution.

Thanks. I've installed libbsd and libmd, and everything else that was missing, from what I can tell.
But the result is not much better. It doesn't know what du_link is.

Honestly guys I'm starting to worry that Swift is the Butterfly Switch of languages i.e. poorly concieved and executed. When is this compiler going to build on GNU/Linux, preferably on a Linux distro that people actually use (not Ubuntu)?

Just wondering which GNU/Linux you are using. Could you elaborate a bit i.e. where can I download / install etc.
Thanks.

I doubt that people will be inclined to help you given the snide remarks at the project. This is not a small project at all, and there are a significant number of people working on this and building the project continually. There are differences in between your setup and others, which means that there will be issues that you will need to deal with.

As to the actual issue, LIST_FOREACH_SAFE is defined in libbsd, so I suspect that libbsd is not installed in the appropriate location or for some reason CMake is not seeing it. You did not provide enough context to be able to determine that. That should be mentioned in the CMake configure output though.
