I have a simple vibe-d project built with dub. Running the command, dub build --force returns the following output:

Does anybody know why this happens? I am on the latest version of the dmd compiler(2.098.0.) Thanks in advance.

I'd start by running dub -v build --force instead, to see the exact commands that dub is running.

Nothing else seems to be of importance, as all other output is dub building packages.

Nevermind. I edited the source and it seems to work for some reason.

Note that dub -v does not tell you what DMD passes to the linker. I've complained about this before, but I think on discord/slack.

The way you have to see the linker commands is use dub -v to get the link command (which calls dmd), and then copy/paste that command adding the -v flag. Which doesn't always work, since dub will sometimes use temporary files/directories.

For better context, changing shared static this() to void main() fixed the problem.

Why did you use shared static this there? Oh, maybe most examples use that now when I think about it.

Take a look at this guide btw:
