You might try Digger. That will hide all the tedious bits.

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).

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 Since it's a plain install, I suspect the Wiki is outdated.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.

I think using digger in principle works and I assume the problems I got aren't Digger's fault, but ae's. Building DMD + DRuntime failed.

In my working folder (created by DUB running Digger), there's DMD.exe, but trying compiling anything results in "Error: cannot find source code for runtime library file 'object.d'"

I did nothing but follow the instructions on code.dlang.org/packages/digger :

dub fetch digger
dub run digger -- build

I tried building the current version v2.94.2 and tried --model=64, nothing helped.

The error I'm presented is when

>    work\build\bin\dmd.exe -lib -ofphobos64.lib -Xfphobos.json -conf= -m64 [..1]
>        -I../druntime\import std\stdio.d [..2]

is executed.
[..1] IMO unrelated options
[..2] following many more std modules, probably all that there are (haven't checked)

The error message is:
> std\stdio.d(16): Error: module stddef is in file 'core\stdc\stddef.d' which cannot be read

I have no idea why the import failed. The stdc subfolder isn't in the core folder, but that core folder isn't even in a druntime/import folder anyway. Something's going horribly wrong.

It seems something beyond us just doesn't want me to get D stuff done. :(

Tomorrow, I'll try setting up a dual boot and give it a shot there. (Not the dub experience  but following https://wiki.dlang.org/Building_under_Posix)

Thank you all for your answers.

Sorry about this. It was caused by a breaking change in Druntime's build script:

https://github.com/dlang/druntime/pull/3026

I pushed a new version of Digger which includes a fix.

Have you heard about WSL...WSL2? You don't need dual boot anymore. Read https://docs.microsoft.com/en-us/windows/wsl/about
