When trying to unit-test an unchanged phobos module from phobos/master, I get errors such as

    module core.lifetime import copyEmplace not found

and template instantiation errors. What is the correct arguments to pass to (r)dmd? I know it worked for me some years ago, but somehow, it doesn't work now.

I've looked at [1], [2], [3] which didn't work (maybe outdated?). How do you do it and what am I doing wrong?

My setup:
* A fresh DMD installed a few minutes ago.
* Clone of my Phobos fork with up-to-date changes from dlang/phobos/master.

In the clone's folder, ~/dlang/phobos, I tried the following commands:

    $ dmd -main -unittest -version=StdUnittest -I. -run std/<module>.d

and

    $ rdmd -main -unittest -version=StdUnittest -I. std/<module>.d

I have the feeling I'm missing something quite obvious.

Do you have clones of dmd and druntime too? If not, try following these instructions:

Why would I need those? I haven't needed them back then.

I typically do:

make -f posix.mak std/<module>.test

For some reason, [1] says `make.exe` would be installed by the DMD installer, but I found none. It explicitly says not to use GNU make. (I'm on Windows.)

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?

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 Since it's a plain install, I suspect the Wiki is outdated.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

I wrote that not saying "do the work for me, guys" but "please tell me what changed".

Phobos depends on DRuntime, and both Phobos and DRuntime depend on the D compiler. When you download version 2.094.2 of the compiler (the latest release), it comes with the corresponding versions of Phobos and DRuntime, and is configured to automatically include them in its import paths.

If you want to compile the development version of Phobos, you will generally need the development versions of DRuntime and DMD as well, because of the dependency relationships between them. If you try to compile the development version of Phobos using the latest released versions of DMD and DRuntime, you are liable to run into dependency issues like the one in your original post.

I have no idea what changed for *your* setup, because (a) I develop on Linux, not Windows, and (b) I've only been involved in D development since 2018. Personally, I followed the instructions on the "Starting as a Contributor" and "Contributing to Phobos" pages, and they worked for me.

The digital mars make is actually distributed with the c compiler.

Developing on Windows is such a complete pain e.g. setting it up so it can find the linker and cl. For that reason I currently just do all dmd/phobos/druntime hacking inside WSL because that way I can just press build (dmd has build.d which is cross-platform but druntime and phobos both aren't fun to build on windows unless you've done it recently)
