It's when I don't have it set, or set to 13 that I get those linker errors. Maybe this would have been obvious to a C or C++ developer, but I do all my professional development on scala and thank you for your help.On Saturday, 19 August 2023 at 21:35:25 UTC, Alexander wrote:I think that thread is where I originally found the bandaid I described: https://github.com/ldc-developers/ldc/issues/3864#issuecomment-963304679Completely new to D, and when trying to setup the toolchain,Could you please specify the versions of macOS and DMD?

I haven’t yet set aside time to report it as an issue.
