Willem A friend of mine was with this issue. We just end up using ldc2 but would be nice to know the actual fix for dub with dmd I suspect my initial issue was related to the Visual Studio 2019 installation. I didn't install the "Desktop development with C++" components the first time round. See 1m35sec in video link provided.

I just ran into this issue as well. I haven't had a chance to fix it on my end, but this is what I've found. This line Performing "debug" build using C:\D\dmd2\windows\bin\dmd.exe for x86_64. means that it is compiling a 64bit program on Windows. On Windows, if you are trying to compile a 64bit program, then it will try to link with lld if it cannot find a Microsoft linker [1]. The failure is likely due your Microsoft linker (or lld) either not being installed properly or wrong version or configured improperly. If you don't have Visual Studio Community installed, that might be a first step. Another short-term fix might be to try compiling with the -m32 dflag (need to put in your dub.sdl/json).

[GTK-D] dub run leads to lld-link: error: could not open libcmt.lib: no such file or directory
A simple example I tried to run.
#!/usr/bin/env dub
/+ dub.sdl:
name "hello"
dependency "gtk-d" version="~>3.9.0"
+/
import gtk.MainWindow;
import gtk.Label;
import gtk.Main;
void main(string[] args)
{
Main.init(args);
MainWindow win = new MainWindow("Hello World");
win.setDefaultSize(200, 100);
win.add(new Label("Hello World"));
win.showAll();
Main.run();
}
This is how I tried to run it.
C:\Users\vaida\Desktop\Command prompt shell>dub run --single gui.d

Re: "lld-link: error: could not open libcmt.lib: no such file or directory"
in case anyone else suffers from this in the future and is looking for a solution - redownloading visual studio 2017 and making sure the c++ workload was enabled fixed this for me. i'm not really sure why that worked, but i'm just happy to be able to learn again. trans rights! - moth
"lld-link: error: could not open libcmt.lib: no such file or directory"
hi all! after a long while away, i thought i'd download the latest D release and give learning it another shot. unfortunately, it looks like i screwed up somewhere big time =[ it was working fine for me before [a few months ago i think], but now whenever i try to compile i get the message "lld-link: error: could not open libcmt.lib: no such file or directory". sometimes, depending on what i'm trying to compile, it complains it can't find "OLDNAMES.lib" as well. i thought it was just that i had installed D wrong at first, but i've uninstalled / reinstalled a dozen times now and it's still not working. could i really have deleted whatever it's looking for somehow? i really want to be able to program in D, but i'm at my wit's end... please help! =[ - moth
