What about this?
We can build it without systemd on non-linux. :)

Good idea. Unfortunately it fails to build on darwin.

Let's hope this fixes it :D
@GrahamcOfBorg build yder

Oh, can you please have ofBorg run it on Darwin? @markuskowa
I'm not a privileged user so it doesn't build there.

Still fails on darwin.

Yes, still fails, but now during linking the test executable:

My new patch might fix it.

Alright, I think I'm close. (Thanks for rebuilding :))

Don't know why it works on Linux but not all libraries are linked to the test binary.

Still the same problem.

Even more fixes:

• Test for journald logging is not systemd specific and fails on darwin
• If the working directory is different from the build directory, the
  dynamic linker can't find libyder

You're sure you don't want to restrict it to Linux only? Without a mac it is pretty hard to test. In the end we might make it compile but that is no guarantee that it also runs reliably.

Yeah, you've got a point. But I'm so close ;) Got all the linker errors fixed and now only the test is remaining. I think I fixed that now.

I'll split my fixes and upstream those patches ASAP.
When it at least builds on darwin, other people can provide upstream with feedback whether it reliably works. Maybe even Nix on Darwin users.

Looks like it works now.
