copyEmplace isn't in druntime 2.094.2.
My guess is that the problem is caused by trying to compile Phobos
with a compiler that uses an incompatible version of druntime.
One of the issues is, I don't know what DRuntime really is. As far as I
understand on the surface-level, it's functionality one would expect to
be implemented by the compiler, but actually implemented in plain D
code. A low-level Phobos if you want. So I'm a little confused why
there's even a need for it to be "built". Isn't it "just code" like Phobos?
Druntime is in many respects the library portion of the language. It's
the glue that allows some language pieces to work (e.g. Object,
associative arrays, TypeInfo, etc.). There are also pieces that are
purely independent of the compiler.
But it used to be that just Phobos existed, and no Druntime. Druntime is
actually the runtime portion of Tango, factored out so that both Phobos
and Tango could use the same underlying runtime. It used to be, if you
wanted to use a Tango-based library, you couldn't use a Phobos-based one
as well.
At this point, it's a nice separation of the Language features that must
be library implemented from the user library (Phobos).
I'm increasingly frustrated because, honestly, it seems I don't know
enough about the build processes or build tools used. The Wiki expects
Digital Mars make to be there, also says explicitly not to confuse it
with GNU make, but in my DMD folder there is none. Since it's a plain
install, I suspect the Wiki is outdated. How am I expected to figure
things out? It seems like everyone else knows how to do it, just I'm too
stupid.
Like any projects that are built over decades, Phobos and Druntime have
accumulated esoteric build systems, and things you just "have to know".
I honestly can't help you with your troubles, because I only ever use
Windows when I have to. But I'm sure there are ways to get done what you
want to get done. This might involve wrestling with the build system, or
figuring out the correct command line based on the build system.
