Which component and where is the problem?

The Phobos build depends on Druntime and makes the assumptions that it is in ../druntime via the:

	${MAKE} -C ../druntime …

line in the posix.mak file.

I would have thought DMD, Druntime and Phobos should be buildable independently but this seems not to be the case, in which case they should perhaps be a single multi-module project.

How do GDC and LDC relate to Druntime and Phobos?

GDC and LDC both use druntime/Phobos, but integrate it into their own build system instead of relying on the makefiles in the upstream repositories.

Not much in D compiles without druntime, for the vast majority purposes it's a necessity.

Also, there are bits of the language itself that are dependant on phobos (x**y)

The 3 are pretty inextracably linked together.

Phobos must build druntime because on Posix the druntime library is integrated within the final library, libphobos.a.

That is controlled by the line:

DRUNTIME_PATH = ../druntime

in posix.mak. What would be a better default?

The order to build things is dmd, druntime, phobos. Perhaps it was not the best idea to make them separate projects, but I think we're stuck with that now.

I don't know.

I get the feeling GDC and LDC would be hard to manage if druntime and Phobos were tightly integrated with DMD so that split is actually good.

I think having DMD, Druntime and Phobos as distinct Git repositories is right, which means that using a super-project such as https://github.com/carlor/dlang-workspace with the three as submodules makes a great deal of sense. Then GDC and LDC can organize things as they need.

I didn't know there was such a thing as a super-project!

You can integrate git repositories into other git repositories as submodules.
