Strangely I just got similar link errors (phobos64.lib ... unresolved ...) building dynamic lib on Win11 (no errors on Win10, or with ldc). I found this thread and adding main() saved me.

Any expert can explain why and when main() is needed for dynamic, or static lib?

Oh, I'm not saved. Because now I get "only one `main` allowed" error when I link the lib.
